I have an Astra 2.0 sport (1996) And its going for its MOT on Monday. If and when it passes I'd be looking at getting a decat pipe for it. The thing is, I've had a Scorpian s/s catback system put on, with a twin monza style tailpipe put on, and it doesn't sound quite how I expected, will a decat pipe make any difference to the sound? I know power should increase etc, just wondering if they are worth investing in??
Cheer for any help
