My 1 currently runs a full Hayward and Scott decat system with an Andy Forrest twin boost map.
I would like to return the car to something like an original exhaust system as the Hayward and Scott is a tad noisy.( albeit a wonderful sound )
So would like some advise on which system to go for without compromising power if possible.
Appreciate that I may need to get the engine re mapped to suit.
Any advise gratefully received.
Carl.
