I have just done a deal on a MK4 Astra Gsi. The first thing I want to change is the exhaust to reduce the horrendous ott noise!
It may have had an aftermarket type fitted, I'm wondering if it's possible that changing just the back box will help? The bore size seems huge all along the system but being new to these cars I'm not sure if it's a standard size or not...
Second question would be the air-con. Is there a weak point on these cars? The clutch isn't kicking in, so the gas must have escaped or the pressure switch is u/s.
Thanks for any help.
