Hi,

got '08 ISF stock. Want to increase performance. Which setup do you recommend?

Do a search, there are many topics on this and dyno sheets to go with it.

Joe Z Exhaust System, PPE Headers. Intake will give u some extra hp but the Exhaust and headers will do wonders

~joe z or hps intake (last)
~sikky or ppe headers (Do first) theres lots of debate which brand is better but they both make similar power and many member are happy with both brands.
~joe z, borla, ppe exhaust (second)

~Nitrous when your ready to party 500-600 wheel depending on the shot and supporting mods

You really don't have many options - what Darbs stated in post #5 is all you really have to pick from. Most guys have a PPE/JoeZ setup for H/E. You're not really getting anything from the intake except a little change in the note of the sound.

Thanks for your replies.

Are there any videos or soundfiles of the different exhaust types? Do they sound the same?
The deeper the better.
