Simple question in title. Looking for a decent exhaust system for my mostly stock Z, came across many reviews saying these SLP systems are some of the best systems for stock manifolds and cats. It has both of my needs/wants: HP gain and great sound.

My question is if it will fit, with no modifications, on a LT1 based engine. Everything says they are for LS based, and I have seen a few videos of LT1 cars with this exhaust system, but I just want to know if anyone can absolutely confirm this system fits like a glove.

Thanks!
