Mazda MX5 Mk2/Mk2.5 1.6 GT25/28 Turbo Exhaust Manifold + Downpipe + 200 Cell Sports Cat

This is the exhaust manifold, downpipe and centrepipe with 200 cell sports cat for the Mazda MX5 Mk2/2.5 1.6.

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.

What’s inside?

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.

There is a 200 cell sports cat which can be run permanently as long as the car is mapped well and you are not using any feature which causes excessive flames, for example anti-lag.
