The STM stainless high flow cat for AWD 3000GT/Stealth features a full stainless steel construction, tig-welded in house at STM and utilizes the GESi GEN1 ultra high output EPA compliant catalytic converter.

This cat will fit in the factory location with the stock downpipe, but will require an aftermarket cat-back exhaust with 3" compatible 2-bolt flange. STM is currently developing a stainless steel cat-back and downpipe. We will update with installed pics soon!
