Headers . . .

Boy am I glad I didn't just go out and buy headers impulsively (like I do just about everything else).

I don't want to get a great deal on some KOOKS headers and then get a stupid 'check engine light' message after spending all the loot.

I also don't want to feel good about getting a great deal on some KOOKS headers and then be told I have to spend another $300 + to get rid of the light (while at the same time buying another mod in the Dashawk).

Can anyone tell me a simple way to research a list of available manufacturers that produce quality header kits for our great vehicles that will not produce errors and require additional mod purchases to offset quirks?

I'm all ears . . . please . . .

2007 Grand Cherokee SRT8 black
2000 Ducati 996 Red biposto (modded out)
2000 YAMAHA R1
2005 Big Dog Ridgeback - Mono Metallic Silver
2003 Honda Oddysey Burgundy -hers
2006 Jayceman - (July 2 model) little boy (Jayce)

Search button is your friend, but since I'm bored at work right now...


There are two choices of headers for the GC SRT8 right now. Kooks which you seem to already know about and Stainless Works.

Other thank Gotstroke? I don't think anyone else has a set of Stainless Works on their Jeep right now cause they're new to market. SW did the right thing by using a higher cell cat and locating the O2 relative to each, so it doesn't set a CEL. I'm pretty sure they'll make good power too (~20 to the wheels).

IMO SW is the way to go for headers right now. Bang for the buck there might other areas to consider, but again that just my opinion...

I was trying to figure out which set of headers is the best. I dont care about CEL that much since I have dashhawk. Obviously I would rather not have.

I want the best bang for the buck

As stated above, you have two choices other than going custom ($$$), Kooks and Stainless Works. I don't think you can beat the GP/Sale pricing for Stainless Works products right now (Southern Hotrod) and their quality is second to none.
I have over 700 miles on my Jeep since the full Stainless Works exhaust install and no CEL/MILs. In all fairness though, while the light is annoying, the headers will still make power regardless.
There should be a few threads on the first two pages of this forum with more info on the Stainless Works/Kooks systems.

Are you making 369WHP after or before those mods in your sig?

I made the same before the full exhaust as after on the same dyno. The Jeep had around 6 miles on it between fitment and the dyno, and it bellowed black smoke when strapped down. It was obvious it was way too rich and timing was being pulled. I've yet to redyno since I've put more miles on the system, but it no doubt feels faster at this point than after I initially got it back.
I plan on redynoing after the B&G or Diablo tune at which point I think the full value of the exhaust will be realized.

No CEL's yet? After I installed my headers it took a while to get the first CEL, do you have hi flow cats also?

Did your guy say that you would get a CEL or not?

Tony,
Knock on wood, no CEL/MIL from either the full exhaust (with 3" metallic substrate cats) or the 176* T-stat. LOL, maybe my dashlight is burnt out
I don't think the SWorks guys knew for sure whether I'd trip one or not to be honest. The good news, as you know, is that the secondary 02 sensor MILs can't hurt performance.
