the 2nd gen 4in down pipe will fit but it get tight by the fire wall i took a porta power and pushed it back a inch for clearence but a bafh will work to just not as clean of a look

 

alright, thanks, ill have to do some shopping around, would you guys recomend against a used turbo? the s300 came on c7 cat motors right? when i do the turbo upgrade, i think ill do the intercooler at the same time, since my truck is 2wd, ill probably do it this winter when i dont need it all of the time :P and ill do some research on that timing spacer, thanks again
