tC spipe mod hp gain?
I was thinking about keeping my stock header and exhaust but changing the Spipe and adding the supercharger next year. Does anybody think this would be my best bet? What is the power increase w/ just the spipe change? I dont want to change my header because of the cell issue and the increase in sound so I might add a new catback later but was wondering how things would be if i added just the Spipe? Does anybody know the performance change that would take place if I had a completely stock car but a k&n intake (which i currently have) and a new spipe?

also - when installing a new s-pipe ---do you need to add any other hardware so this spipe will work? ....meaning ...like the header... are you going to throw a cel or anything of this nature?

Its not so much the header as the exhaust sytems out there are not capable of handling the extra flow and the built in rasp the engine develops. It seems that cars with the proper resonator setups arent raspy with headers at all. Nobody has come out with an exhaust sytem developed for cars with headers so they have all been raspy. Hopefully the new Draxas sytem with resonator will sound good with a header installed. Im also interested to see what the precision muffler cat back sounds like..they use a pretty big magnaflow muffler that should be able to help kill the rasp.

I like the way it sounds but have come to reality and im not going to swap out the header due to warranty issues. Since im getting rid of one of the cats I want the extra power but not going to do it. I like the video but the third one sounds a lil bit raspy (but overall it sounds nice).
i wouldnt spend $400 on a trd for 1hp. im going draxas soon as they release it.

gwtc... does your header comes with the pre-cat or not? i saw a pic of a megan header with a little pre-cat, i guess that since i'm looking to keep my car as quiet as possible, yet i want to add a header, it might be better to get the one with the little pre-cat...

I have just the CC S-pipe and no other exhuast or intake mods.
It starts off the line better, it feels smoother through the rpms with a little bit less drop. No dramatic speed increase but overall it drives better. Plus I'm ready once I install exhaust and possibly a header.
