Hi
I recently started hearing quite a loud noise when accelerating, starting at about 3500rpm. OK, I thought, the exhaust has been patched up a couple of times, let's get it replaced. I got the whole exhaust system replaced yesterday, but I'm still getting the noise (I'm not sure if it's quite as loud as before). I haven't had a chance to get it checked out yet. This is on a 98 Astra mk4. Any ideas?
Regards Keith
