im goin turbo soon and wanted to know if i could run about 15 psi with the apexi world sport muffler??? im wondering because of its smaller inlet and outlet will it restrict my performance.. im at the point where i have a bad exhuast leak and my everything needs to be redone so need to know so i can look for another muffler or just fix this problem

 

i would say if you have the money get a better exhaust piping and keep the muffler. if not i would just fix it. that muffler will be fine.

 

Get 3" stainless steel piping and a megan racing universal muffler.

 

so when goin 15 psi do i have to get a 3 inch exhuast??? if so then i would have to get a new muffler then because the inlet and outlet of the ws is smaller then that

 

so noone else can help me????

 

just get a thermal research and design full 3"
