Mazda MX5 Mk2/Mk2.5 1.8 GT25/28 Turbo Exhaust Manifold + Downpipe

This is the exhaust manifold, downpipe and centrepipe for the Mazda MX5 Mk2/2.5 1.8.

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.

On the hot side, the manifold supplied is a 3mm-thick log type, this will flow enough for over 300 BHP. The downpipe has an M18 boss welded in for a wideband lambda sensor and connects to the standard exhaust just after the diff.
