Ok i have a 2005 GT conv, I have put the procharger 1-sc1 kit on, 373 rearend, and just installed a cryokit... looking for the next step... right now i have stock exhaust mainly cause i want to keep it a sleeper... Any advise would be helpful!
Thanks again for help on earlier post with out wouldn't have gotten this far...!

 

dynotune if you don't already have one. you might also start thinking about a clutch for sometime in the next year or two, depending on how much you beat on the stocker.

 

Forget being a sleeper......longtubes, h pipe, flows, and cams.....wake the dead!
But that's just me......lol

 

+1. How many Mustangs out there have louder exhaust, it's almost common place! I say American Racing Long tube headers and a good dyno tune.
