    Call me tomorrow on my cell to discuss.

    I personally would never run LTs without a tune. A few hundred bucks is much cheaper than a new engine.

    Tune tune tune to take advantage of new flow characteristics. At the very least need the primary O2 sensor response time requirements increased to account slower system response due to lower gas temps. I installed "spark plug anti-foulers" (haha) for the secondary O2's to fix the catalyst efficiency CEL. Other than that, Im Eaton swapped so my $0.02 is really only worth like $0.015
    2004 Silver Birch w/moonroof. "Isabelle"


    Eaton swapped summer/fall 2015 with all the gooddies, tune by the one-and-only Marty-O +2psi pulley, Steigemeyer stage 6 port, SWLT, custom ss exhaust, Borla ProXS, Addco sway bars, TCE s/s brake hoses, Hawk HPS pads, Zack big brak kit, J-mod, battery in trunk, full custom audio (never used, blower whine sounds better)

    To do list:
    HID headlights, LED interior/exterior, courtesy "3-flash" turn signals, widen wheels, rear deck wing, marauder stencil on cmhsl? bumper cover inserts? deck lid, steering whee, hood liner godshead, more power!

    "O2 transport delay" needs to be raised in the tune for optimal efficiency. Unless there's something wrong or you're already running on the ragged edge, it isn't mission critical. Talk to Marty, he'll steer you right!

    No, with LTs, it actually takes longer for the exhaust pulse that left the engine to get to the O2 sensor than in it's original position.. It's a distance thing. You can actually turn the O2 internal heater up if you want also.

    I did a bunch of bolt on's and custom exhaust (not headers) and had my Marauder dyno tuned many years ago and it was well worth the money. Real seat of the pants improvement in performance.

    Talked to Marty on the phone today...got some good info and think I may go with the no-cat headers (I am emissions exempt), factory H/muffs/res tips, and mail tune for now.

    Just need to make sure my holiday bonus check isn't a 'jelly of the month club' membership before I pull the trigger.



    Based on what I'm reading, a lot of the pros seem to like reusing the factory studs...mine are sorta rusty. Seeing conflicting info - some hating on the SW-supplied bolts, others saying it's fine. Some like the FRPP locking bolts, others hating them. Advice here is appreciated.

    Will definitely be using factory gaskets.

    Mine has the supplied bolts installed. Haven't had any backing out issues or anything like that. I also didn't install mine.

    I’ve done a few header installs and have had great luck just using new 8mm studs and factory lock nuts. They sell 10 packs for about $12 at all auto part stores, either Dorman or Help brand, that’s all I use. You could also splurge on Stainless studs online, I just didn’t bother because of easy to grab locally. Besides, mine isn’t driven in snow.

    You will need to cut a couple down on the passenger side but that’s easy. So far I’ve yet to break an old stud. Been lucky.. When they snap in half it’s normally right at the face of the manifold. Plenty of meat to double nut it and remove. Helpful hint, try to tighten it till it cracks loose, then walk it on out.

    And yes, factory gaskets.

    On a side note, I went cat less for a year or so and couldn’t take the stank! Tbone tried as well and went back to cats! These engines wreak..

    I used these, I highly recommend factory style studs, no reason to get overly fancy here.

    If you do snap off the EGR line I'd recommend replacing with this:

    Worked like a charm when I put SW headers on my car and is much cheaper/easier to work with compared to the rigid factory one.

    Noted on both suggestions; thanks!

    Unboxed the headers yesterday.

    I am not a welder, but the EGR bung weld has me a bit annoyed. This may not be the proper term, but there is 'spatter' on the inside of the pipe (basically just looks like metal got hot and sprayed through open gaps into the inside of the pipe...yeah...like I said I'm not a welder so I don't know what this is called!). I can and will file it down, and it's not going to prevent the install from happening, but for the price, I don't feel like I should have to do basic finish work.

    Otherwise they appear to be as good or better quality than the Kooks on my Vic (which doesn't have such spatter inside).

    Ordering from Marty was insanely easy, and a pleasant experience. Thank you again, good sir.

    I used these stud kits as well.

    I've also reused the factory gaskets on both my marauders with no leaks. If you're a stickler for new parts, buy new OEM gaskets, they work great.
    You "feel" the difference because you want to "feel" the difference. Since you just spent money on the upgrade you "have" to feel the difference

    I'm looking to eliminate the double pump process I have to follow right now to get the pedal hard

    I actually installed new OE gaskets about 30k miles ago when I lost compression on 8. I bet they'd be fine. But...cheap as they are, though, I think I'll skip reusing and buy new ones.
