Mufflers, thinking of getting new ones.

[StevenJ]

I'm getting tired of the 18 Magnaflows. Looking for something with more noise. I know everyone is going to jump on the Super 40s. I heard what they sound like before but I'd like to try something different. Though I wouldn't mind getting them. I'm thinking of either Hooker Maximum Flow Mufflers, Edlebrock SDT Mufflers, Thrush, the Flowmaster Super 40s, or Dynomax. Anyone got any expereince with any of these, besides the Super 40s? I was thinking about the Edlebrock for a while but I read it has resonators in there to elimate noise. So I don't think it will be any louder than the Mags I already had. I also may end up going with glass pack mufflers but that may be a bit excessive. I have stock exhaust and all four cats.

[phroe]

Here's a suggestion. I've been doing a lot of inquiring about this company

http://www.aeroexhaust.com/

It's an interesting presentation - interesting technology. I've searched for objective info via google and I'm not seeing anything terribly negative.....
Anyone got any feedback?

[03MERCMARAUDER]

I have a sound clip of the flows with an X pipe. Had the 18'' mags and hated them. Get on streetfire and look up marauder. title shooud be marauder exhaust.

Thoose are way too much! Nice find though but beyond what I want to spend. I'm looking at the Hooker Maximum Flow mufflers. Only $120 a pair from Summit Racing. Sound like a nice alternative to Super 40s.

[FordNut]

I have Edelbrock RPM mufflers. I think they sound good. Louder than Magnaflows, not raspy like Flowmasters.

[Marauder386]

( cough ) Ford Racing Performance ( cough cough ) dual mode mufflers...( wheez choke gasp ) .....

:coolman:

[94_302]

I have heard the edelbrock RPM's on 5.0 mustang and I loved the sound, I also like magnaflows as well. Does borla make anything for the Marauder? You would also get a louder sound by just going with a catless x-pipe.

Holy Crap!!!! The Magnaflows are NOT LOUD enough!!!???
I guess I'm gettin' old because my Magnaflows are as LOUD as I EVER WANT TO GET!!!
As soon as I crack the throttle EVERYONE within 100 yards KNOWS that my SH#T isn't stock!

I can't get a SH#T Box Honda to bite once they hear my pipes....

[BUCKWHEAT]

I'm with Joe. I am interested in a little quieter than the magnaflows. Don't like the drone.

[StevenJ]

Like I said, I got stock pipes. I know Mags are loud on aftermarket systems but not so on stock exhaust. I'm probably going with Hooker Aero Chambred Mufflers anyway. They aren't too expensive and flow better than Super 40s without all the drone. Oh yeah, about Edelbrock RPM, all they got listed is the SDT and stainles steel mufflers on their site. Nothing about that one. I wonder how much they are.

[jim geary]

I'm going to have to agree with Joe on the Magnaflows.Those are plenty loud.
You don't want to scare off all your ricers do you?

[MarauderMarc]

I think you should spend the money on another mod, like gears, before you worry about new mufflers. A decent set will be @250-400 installed. You could get the gears for around that price. I only say this because I know you want them, youve told me. About the super 40s, I know how you dont like to jump on the "band wagon" and get what the majority has, but these mufflers rock! I get nothing but compliments about my exhaust. But if youre set on not getting them, Id say the Ford Racing Dualmodes. The only thing is price. Theyre @ 300 a pair, but well worth it.

[kartherma]

I have the Flowmaster 40's on both Marauders.
The 04 is stock except the 40's. It has a nice rumble.
The 03 is stock except the 40's and a pair of missing cats (that's legal in the state). It is ugly loud.

Heard somewhere here that they get really nasty with no mufflers and the stock tips...have you thought about that route?

be good, Curt

I have Flowmaster 40 originals with the Megs delete...it's plenty loud, and I have not run accross a Marauder that sounds like mine.

Do not take out your stock mufflers and weld in straight pipe...you won't like it.

Yep it does sound a lot better, now Marc.

Steven, I think you should get the Meg's delete tips and extend 1 inch from stock (just so you can read the megs logo, you'll see). They'll fit your budget, give you the extra sound you want and not be a re-mod (read - waste of money), but a new mod.

[FordNut]

... a pair of missing cats (that's legal in the state). It is ugly loud.

That's illegal at the Federal level. Even if your state doesn't do emisions testing it is illegal to remove the cats on a street driven car.

I may do that too. Just so you know, and I pm'ed Mark this, I just bought 4.10 gears along with a new performance T/A Cover and the stud and girdle kit. It just needs to be installed. I'm just thinking of ideas right now. Though, the Hooker mufflers don't sound too bad, I can pick them up locally at Murray's Speed and Customs in Miami for $145 a pair after tax. Delete tips isn't a bad idea though. I thought about doing that.

How about waiting until evething else that you bought gets installed? The RPM difference (about 500 more) may change the pitch and tone of the mufflers that you have now.

Of course I'm going to wait for the gears to be installed. I'm just thinking out loud.

IMHO, It's all a matter of personal taste and how you use the car. Four or five of our local members have had the mufflers removed and pipe welded in, myself included. After about six months I had Magnaflows added back on. I'm the only one to add mufflers back on so far. The difference? Our Marauder is our main transportation - everyday to work for me, all weekend running around, long out of town trips occaisionally. For several others the Marauder is a "play" car. They still love the sound! I love it too, but not all day every day, so I went back to mufflers. If you don't like insane loud when you stomp on it, then, no, it's not for you. Just FYI These are some low quality vids I recorded back then.

So does this mean that everyone who has switched to the Kooks or DR exhaust has violated this? Those cars come out with 2 less cats than stock. I am interested in this because I know that the 2 rear cats are not monitored by the cars computer and i was thinking of gutting or dumping them altogether and throwing the magnaflow X pipe in behind there. I cant afford a full exhaust and I think that if that is doable it will throw a wicked sound...:D

[Marauderjack]

RedMerc...

I gutted the cats on a 5.0 Mustang once and it sounded a bit louder but the empty cat housings ring like a bell when I accelerated.....sounded crummy!!:argue:

I would suggest just cutting them out and putting a pipe in place.;)

Very good ^^^^^ advise.

[LVMarauder]

I just replaced my 40's , I was thinking super 40 but when I went and asked for them I was told they are quieter than the 40's. They had a cut out of the different series and the super 40 had 3 baffles, flow 40's only had one. Sounds really good again.

[TAF]

So does this mean that everyone who has switched to the Kooks or DR exhaust has violated this?

In a word....Yes.

uh...yes they are...you've been misinformed...

depends on how you define "wicked"...if wicked to you means LOTS of drone and ringing? Then you just may accomplish your goal...but I'd high advise against this.

Folks either do exhaust mods correctly...or leave it alone...I tell folks this everyday at the shop...."Any idiot can make an exhaust loud with a sawzall...it's about making it sound GOOD and free flowing for performance that counts."

[mpearce]

IMHO, It's all a matter of personal taste and how you use the car.

True, it's all personal taste. But to me, you can tell when someone has a nice performance exhaust set up on a MM, and when someone just cuts their mufflers out. Cut out mufflers doesn't sound like performance exhaust IMO. Our cars have distinct exhaust sounds...and when all you do is remove the mufflers, you lose the powerful tone, and change it to a "somethings wrong with my exhaust" tone.

But, thats just my personal taste...like you said.

:D

[Joe Walsh]

Yep, Removing any Cats, UNLESS they are malfunctioning, is illegal per the Feds. Even if you replace the functioning OEM Cats with new Cats.

[RedMerc04]

Thanks, I certanly wouldnt want a trashy sounding exhaust. I was just under the impression that they werent monitored and since I dont have the cash to buy a full exhaust such as the Kooks or Reinhart I figured that cutting them out would do something for me in the sound and possibly power department. So Ill just leave the cats alone and do the magnaflow X pipe into my current Delta 40 Flowmasters. I think that should be more than sufficient. :baaa:

Thanks again

I agree with Mat. I did the straight pipe. The drone is unbearable, but i thought what the heck, I'll try a cheap mod.

I had some interest in Dual Modes, and thought I'd try the straights for the hell of it first.

The wife didn't like it....So she said get it fixed for whatever $$$, so there is some benefit to experimenting.

[mrjones]

Has anybody gone "old school" with just plain old glasspacks? I've gone with the delete tips and it's still pretty quiet. I've thought about trying the glasspacks. They sound pretty good on my F150, and they're cheap to boot.

[KillJoy]

Hmmmmm..... Superchargers change the sound of thd exhaust :D

I actually contemplated doing that but glass packs burnout over time and lose their noise reducing ability. Plus, I hate to say it but they are hillbilly mufflers to an extent j/k. Just kiddin about that last part but you can pick up a pair from most auto part stores for $60. I'm better off waiting until I get everything else I ordered installed first though.

[Marauderjack]

KillJoy....

You are right....My blower made my exhaust a good bit quieter....but only in boost!! The first thing I noticed though was NO INDUCTION NOISE AT ALL!!:shake:

I had the PHP cold air kit before and the induction noise was louder than the exhaust......now just a slight whistle that cannot be heard inside the car.:burnout:

I'm talking with TAF about an exhaust upgrade but don't want any drone.....Stay tuned!!:beer:

[SergntMac]

My MM exhaust system was installed in Oct. of '03, and my Magnaflow 18s and Megs delete tips are still going strong. No loss of tone over time, and never any overbearing cabin drone.

Before I did this, I checked with Illinois authorities on removing the cats, because Illinois is pretty hard on this point. Testing of cars every two years, and sting operations on "muffler chops". Almost got caught up in one a few years back.

Illinois' law mirrors the EPA rules, removing them is illegal at state and federal levels, but replacing broken/worn/damaged cats, is not. As long as EPA certified cats are in place, you're cool in Illinois. Your local laws may be different, please check? If you have no local law, you are still bound to the federal statutes.

IMHO, you should install the Megs resonator delete tips before you change mufflers, no matter what muffler is in place now. The OEM resonator negate a lot of tone and volume. Try this mod before changing out any aftermarket muffler, you may like what you already own much better than you think.

Also IMHO, when installing the delete tips, extend them outboard past the rear facia as mentioned ^ there. This is very effective in lowering/avoiding cabin drone. Here's a pic of the results.

http://www.mercurymarauder.net/showcase/showimage.php?i=1295&c=3&userid=392

BTW, I was told a long time ago by Jerry W, that the SCT tune for the Marauder indeed shuts off the rear 02 sensors. However, the wiring harness is still active, so, if you do remove the rear sensors, you'll prolly need to add adapters. Since all the popular aftermarket exhaust kits come with four 02 bungs installed, just bring the sensors over to the new setup?

Just my .02C, gents. Carry on...

[Big Joe P]

Having had several Panthers, I love the sound of the stock system by just replacing the mufflers with straight pipe. The cars have 4 cats which is more than enough to muffle. That was one of my first MM mods, eliminating the mufflers. With or without the supercharger it sounded great. Things changed after the KOOK's headers. I ran them with the supplied mufflers, straight pipes, glass packs, finally settling on Dynomax 6" rounds. Similar to glass packs but lasting much longer... Sounds great at WOT, and a bit more civilized just cruzin..........

I had straight pipes on my Crown Vic for a month or two, back in the day. I liked the WOT sound but on mornings driving home from friends' houses the drone would make me sick...then again maybe the night before was to blame.

I have Spintech Sportsman Streets right now, if you search you'll find my video clips. I like them, sometimes they aren't loud enough. I can't get enough of Big Joe P's exhaust setup, it sounds great.

And I say again...with 2.5 inch original configured SS pipes out to the Meg's deletes or the original resonated tips...

I dont know. Hopefully someone else will chime in......

[STLR FN]

The rear cats are monitored a little further downstream from them.

[supa_carrot]

Well, I don't know if you have made up your mind yet or not but tomorrow I will be having my Flowmaster Super 40s installed with everything else being stock. When I get home and I've heard them enough to make a good decision I'll give you my thoughts.

Curt,
The rear O2 sensors monitor the front cats. They are the primary catalyst and are most prone to failure. I hope that clears up the confusion. Also, as stated before, OE or equivalent cats are federally mandated no matter which state you live in!

Jerry...hope you didn't think I was knocking you. That wasn't my intent. If you decide to fix your "mufflerectomy" I'd suggest combining a new set of mufflers of your choice with the resonator delete tips at the same time. Very nice exhaust note change, for not a lot of money. Do what Mac suggested also if you get the Megs, bring them out from under the bumper a bit...but not far enough where it looks bad.

I didn't take it as "knocking", if I did, then I have issues that only medication would resolve. :) The hardest part of all this is trying to get to listen to all the choices and mods that have been done. I'll have to ride/sit in some more MMs and listen inside and outside. I can window shop at Barry's this June.:D
