Can't believe how much quieter it has made my car.
I took the Cat off the car about 3 years ago when I fitted the RPW downpipes & did the de-cat at the same time. A couple of months later I got a cat back system fitted to the car & it has run like that since.
The members who have seen my car will know its loud. The last 2 Japfest's it came in at 99DB at the sound test.
The car has passed its MOT the last 3 years with the de-cat on but the rules have changed & the cat has to be on the car. MOT is on Tuesday so wish me luck
