Take a listen to this big V8 Porsche Cayenne Turbo-S. we have removed the secondary cats and fabricated new decat pipes with new flanges and pipework for this vehicle.
The bolt in and out set up means there is no hassle in the future popping back in the standard cats for NCT or if the customer decides to sell it on. All 304 stainless.
We generally stock lots of different laser cut flanges, but sometimes a job like this comes up where we do not have the flange available. So we keep blank flanges in stock that we can cut and drill for any application.
