The 200 CPSI high efficiency/flow sports cat is unique in that it is removable, flange mounted at each end between the GTT manifold and the exhaust system . This allows quick and easy changeover without removing or disturbing either part. Why would I want this? Two reasons ,one is it allows our optional GTT ‘cat bypass link pipe’ to be easily substituted for track days & racing, releasing more power and reducing weight in the process. And secondly it gives provision for simple & cost effective cat replacement i.e. you don’t need to purchase a complete new manifold too we have seen some aftermarket sports cats failing after just 30000 miles. This shows as fault code P0420 ‘catalyst system efficiency below threshold’ and can cause mot failure and emissions test fail. With our system should the cat eventually become contaminated, you can purchase just a replacement cat, much cheaper & much easier to fit.
To make this the best available we have a few tricks up our sleeve. This takes a lot longer to produce, but we think the Mini deserves proper engineering!
The flange plate is machined to the exact profile of the OEM manifold gasket; no steps & no restriction. Manifolds with round holes on the top flange plate are no good at all, they however much cheaper to make.
Fits: all Gen 1 petrol models with our GTT spec manifolds.
