Noticed on about a 70 mile journey last week that my exhaust note changed from what it originally sounded like.
The exhaust sounds like it blowing slightly, it isn't overly loud, just a little bit raspier. Anyway, took it down to my local exhaust place and the guy said all was ok with no holes, he let me see the exhaust system with the car up on the ramp. Again no holes etc. He covered the exhaust backbox tips to show me no holes were present.
He said it sounded like the something internal in the backbox had gone but not too worry about it, and that it wouldn't fail an MOT or anything like that.
Sounds like everything is ok after this but the noise is just annoying me. Anyone else had this? Or could it be something else?
