Ok...I ordered my high flow cat from the group buy. Now am I correct when I say that the piping does NOT come with it? So I have to buy separate piping? And I have to get a performance muffler to complete the exhaust system? Just correct me if I am wrong please. Thanx!

 

Yes..you are only getting the catalytic converter...as for completing your piping, why not look into a cat-back system. This is all the piping (including muffler usually) after the catalytic converter. All you need to "really" have a good sounding and high flowing exhaust system after all this is done is a nice header.
