even with my 709 whp target, I'm stock after the cat, and it is the base system too
crush pipes and all. I spent my money on more fuel and E85. My exhaust is just about right, not too loud, I do wish I had a slight bit more cam sound.
Oh I really like Cunningham's progression:

1) supercharger tune
2) supercharger cam headers tune
3) supercharger cam headers E85 tune
to me this is easier on the stock pistons then just upping the boost. base, base plus breathing and fuel, the e85 with about the same or just a tad bit more boost.
I know the cam change is expensive, I'm just saying to my mind this is the most logical sequential build.
