Mazda MX5 Mk1 1.8 GT25/GT28 Turbo Exhaust Manifold & 2.5″ Downpipe

This is the manifold, downpipe and decat pipe for the Mk1 1.8 MX5

It has been designed to run using a Garrett GT2860RS or GT2871R or any hybrid using the same dimensions. This gives you the flexibility to choose to go for a cheap eBay version, a second hand unit from a Nissan 200SX with the compressor side adapters , a Garrett GT2860/GT2871 or even the much loved Disco Potato.

Once fitted this will bolt up to the standard catback system found on the cars with either the 370mm or 440mm cat fitted, these exhausts are found on cars made between 1989 and 1996.
