I just got a set of pettit pulley's on as well as a Blitz Nurspec exhaust. I can't really tell much difference in power, although it's been wet out since I picked my car up yesterday from pettit. I already had the intake and d/p installed do i'm hoping for at least 250rwhp.

Two things I did notice is that the blitz is loud as hell and put out alot of heat. Is my rear facia going to melt? I never realized how much heat the stock exhaust insulated.

 

No your rear facia is not going to melt, it's going to dirty though.

 

I keep it washed about twice a week so that shouldn't be problem...

 

Just don't do a mp, it is hell to scrub that crap off on white FDs.
