maybe 5 rwhp in your application.

SLP LM II's + o/r X pipe = 233rwhp on an 01' GT

I timed myself 0-40 and 0-60 before and after installing the SLP LMII's. Only a minor decrease in time, but OOHHH the difference in sound!!!
I just ordered the SLP Catted X-Pipe, and expect the sound to become OOOOHHHHHH so much better yet.
