I am strongly looking at going with the Kraftwerks SC kit, but want to maximize my output as long as I going for it. I will be driving on public roads so I must retain the cat., but was wondering what else I could do with the exhaust that would be most beneficial. Do you see more with a cat-back vs axle-back, or is about the same as you are still dealing with the cat? Does an aftermarket header help or just a waste of money?
I am really hoping someone from Kraftwerks will pick this up and respond, but if you have had a really good, or bad, experience with the subject, feel free to chime in. Thanks all

 

I would suggest going with a megan header and megan cat back. For other power adders Id read more into the KWSC threads.

 

OSR said the Megan 4-1 Header gave good gains while the tri-y WeaponR street header actually killed some power. So, any quality 4-1 header will probably bump up output a tiny bit w/o leaning it out much.

 

i have j's racing header and t1r b-pipe and j's racing axel back. i had these on when i put the KWSC on before so i can't tell you the difference but im pretty sure it made a difference.

as far as bad experiences i was so lucky to have something go under my car and destroy the rotrex oil filter and seize up the rotrex. i'm the only one that had this happen to. you shouldn't worry to much about it or you can just get the beatrush underpanel
