So basically my car has started to be louder,if that makes any sense and I think it’s revving itself just a tiny bit.
The back box is way louder than it should be and I have no idea why
It’s never usually this loud
Engine is fine
No dash lights
No other problems apart from the loud exhaust at idle
Drives lovely

Any ideas? Lol

exhaust could be full of holes

I would say Backbox is starting to blow....looks like it gonna be replacement time soon as it will get louder and eventually fall off
Forget Kwikfit, they quoted me over £100 for a replacement, i got one off Ebay for £20 and fitted it myself....works just fine and i begrudged the thought of giving Kwikfit nearly £90 for the privilege of fitting it for me
