The Cat-Back should not require new hardware...... The stock exhaust has hangers with studs for the X/H pipe to muffler connection that need to be reused to properly support the exhaust system. The only other connection is to the cats and the cats have 2 studs and 2 bolts that can be reused. If the hangers with the studs break, you should buy new nissan hangers. I live in California so I never see the hanger studs break. I am sure in other parts of the country that could happen though. We supply new hardware with test pipes and down pipes because they are needed, But the Cat-Backs should not have regular bolts and the hangers should not need to be changed in most cases.
