    aftermarket performance exhaust basics

    yea, it has a lot that could be replaced and looked at, i just took it home and plan to give it a good once over and catch up on overdo maintenance left over from the PO. I wasnt planning on buying a new pipe but it needs replacing so its a good excuse.
