I am stuck bewtween kooks longtube headers and stainless works. I am trying to decide if the kooks are worth the extra 200. For those of you with them or have heard/sen them care to comment it would be appreciated.

I'd say go with Stainless Works... Fitment is 100% perfect... I got 24.7RWHP from the exhaust
Hit me up with a PM if youre interested in a SW system. I got mine from Speedtech, I can get you a good price!
Here are the gains of before/after the exhaust. No tune changes
No hanging below the frame...

I got 19.4 wrhp from just a lethal OR/X and a set of Corsa axle back ....so it looks like headers are only worth 6 wrhp !
I know our cars benefit from a good set of LT headers but for me the stock manifolds are working out great.
with CAI and tune my car made 406rwhp/387rwtq thats real close to a LT only car and not far from a car with LT,CAI,tune
also this is with a mild 91 oct tune I could squeeze another 10 hp out of my set up easy.
here in Cali Longtubes are illegal so that was my main reason for not installing them.I would really think about where I'm going with my car as far as future mods before doing longtubes.
my car with HF cats/X-pipe and Magnaflow comp series catback can easily hang with a car with longtubes in any type of race.The stock cats are the bottleneck in the exhaust with this 5.0
Who makes and sells just a set of high flow cats????
once I went to the HF cats and full 3" exhaust this baby came alive
If you have the money and dont have to worry about smog etc.then Longtubes are a good option and will make good power but you should check out a car with stock headers and bolt on's and see the bottom end pull they have!!!!
