Will 2.5 inch piping bolt directly to the stock cat or will i need to buy a new one? Thanks in advance.

Im pretty sure that if you buy a cat-back that is made for our cars then it would bolt up.

Ok thanks for the help. Maybe this should be put in the Things we've seen before section for more newbies like me.

my pacesetter one bolted right up. you wanna throw in a new gasket, and usually it comes with the system.

i would definately ask the vendor b4 buyin

Well... a 2.5" pipe and flange won't bolt up. When you buy a bolt on exhaust they actually start the pipe at 2" (stock diameter and increase out to 2.5" so buying a bolt on no problem. Making a custom one you will need the reducer down to stoick size
