Hi people, recently fitted an afterburner de cat section to my 01 sport.It's been on for a couple of weeks now and the sound has improved, but i get a really funny air rushing sound. I know without the cats on it it may make some sort of a different sound, and thought it would improve when it gets coked up a bit, but it hasn't changed that much. Also i fitted a std tailpipe off a turbo version, which now makes a weird rattly type (ish) noise when you come off power or turn the car off?? It only started doing it the other day, and was wondering if anyone elses does this, and is it normal???
Apart from the noises it is quality
