91-94

Looking to buy a set of cats for my 93 NSX. I don't really care what CELL count they are. My original cats are old and rusted out, and I am tired of having my current test pipes on. Thank you.

Hi guys, If you have an ecu laying around good or bad please PM me. My friend needs an ecu for his NSX he's putting back to stock. Thanks! Brian

These came off my 1991 NSX with 97k miles. Works greats, passed Ontario emissions with ease. They are missing the heat shields as they got butchered when they were removed. $200 + shipping. Pick up available in the GTA.

SOLD - please lock Bought them used, but never had a chance to install them. I switched to Prospeed HFC. $100 + shipping. Pick up available in the GTA.

I bought a set of 91-94 stock cats and I noticed that they are hollow inside. Is that right? I was expecting some form of honeycomb structure inside. How is this different than a straight pipe? Inside view
