The Z32-generation 300ZX Twin Turbo’s VG30DETT rewards a free-flowing catback, and the aftermarket for this 1990s JDM icon is smaller than it once was but still very real. These are verified catback systems built specifically for the Z32 2-seater platform (which is the only body style the Twin Turbo was ever sold in), from race-proven Japanese brands to a budget stainless option.

Buying tips
- Confirm 2-seater vs. 2+2 before buying – the Twin Turbo was only ever sold in the 2-seater body, and several catbacks (including budget CXRacing-style units) are cut specifically for the longer 2+2 chassis and will not fit.
- A catback alone won’t unlock the exhaust’s full potential on a modified TT – it’s most effective paired with a matching downpipe/mid-pipe, since the factory Y-pipe is a known restriction point.
- Stainless resists the rust that’s common on 30-year-old factory exhaust hangers and heat shields; budget for new hangers regardless of which system you buy.
