How much horsepower or performance difference can you expect by going to Kooks headers with the stock exhaust from the mufflers back, on a Trilogy equipped Marauder? Who has the best deal on the Kooks?

I may be up for some too. Maybe a group buy?Originally Posted by JoeB

I would think that the best deal on a Kooks exhaust system can be had directly from Kooks, but I could be wrong. But since my car is only puting 400 HP to the wheels w/the Kooks system and the Trilogy set-up is intended to put 385 HP to the wheels w/an otherwise stock Marauder, then I'd say that I've only gained about 15 RWHP from the Kooks system once my car was S/Cered. But the Kooks system does make the car sound sooooo NICE!!!
My car is Trilogy/Kooks equipped.
It made 426rwhp/407rwt.
I have a plasma booster module and a smaller pulley...so my educated guess is that it should be around 400-410rwhp depending on other minor mods...intake, etc.
A Kooks exhaust on a Trilogy machine makes an amazing sound.

Yeah, he lost me w/that "plasma booster" comment too. is that like a blood booster? Anyway, Dave, you probably already know this, but incase by chance you don't, let me suggest that you check w/Lidio to ask him if a chip re-burn is needed w/the Kooks exhaust since your car is S/Ced. It might require a different air/flow ratio setting.Originally Posted by MI2QWK4U
Well this is the first time I've posted it but since adding the Kooks and a few other goodies from Lidio my Horse power has gone from 407 to 460 and my torque is has gone from the high 380's to just shy of 440. I thought my car was fast before but now it is scary. My best 1/4 mile times with the new power are 12.02 @ 117mph.

I think that even though the Kooks system has given your car some more power, much more of that extra power is due to the high boost pressure your pushing w/that smaller pulley you've chosen. You went from 9.5 PSI to 12.4. A 3 PSI gain in boost is quite a significant jump. So I think that if you did that even w/out the exhaust, you still would've been at 445, or 450HP.
It is an ignition spark enhancer. When I tried it I didn't get any increase in hp/tq at the peak numbers, but picked up about 10 ft-lb tq at lower rpms.Originally Posted by MI2QWK4U

So then you're saying that your car gained 53 HP at the wheels from the Kooks exhaust alone? Can that be right? I've never heard of that on a S/Ced engine. If that's true, then maybe the headers and freer flowing exhaust benefit the 4.6L engine more once you get to a certain boost level. Is your 460RWHP figure on pump gas just like your 407HP figure was? And were both of the 407 HP and 460 HP dyno runs calculated in "S.A.E. corrected" figures?Originally Posted by JET

Best I can tell is that Kooks are worth about 20-30 RWHP on a MM that has a Trilogy making the stock 9.5psi of boost.
This is of course putting the Kook’s on a Trilogy MM that already has a better then stock MM muffler. And when we’ve done Kook’s… It’s been Kook’s and a 2.5” X-pipe with two high-flo cats plus upgrading the rest of the system to 2.5” as well. So to some extent it’s more then just a long tube header that’s being added to the car.
And on Trilogy cars that are upwards of 12-14psi, the full exhaust deal with Kook’s will net even greater gains at rear wheels.
Most of the Trilogy equipped MM’s that I’ve done now that are in the 13psi range, full 2.5” exhaust with Kook’s, good mufflers, better MAF will make about 450-470 RWHP and near 500RWHP with 100 unleaded race fuel tunes in them. This with 4.10’s and the stock, tight torque converter makes these cars go low 12’s, high 11’s with good traction and cool air.
Thanks
I may not be at the top (yet) but definitely on top of things.

I found a 24 hour station in my town that has 93 octane. Also found another station (non 24 hour) that has 104 unleaded racing gas
Might be calling next summer for a few minor changes!
