Re: sick of my exhaust.
ok, im dragging this one back up. im back to square one. the exhaust has not so much a rattle, but a possible vibration. the last sports cat i had fitted was knackered due to paste infront of it..may have been my fault, may have been the fitting garages, not sure.
the new one seems fine, only "vibrates" under load, really really sounds like a blow, but ive used 4 whole gaskets between downpipe and cat, plus flange sealant suitable for manifolds, and i dont think it is a blow. i cant feel any air escaping while im under it with the engine running. anywhere.
if anything, it sounds like this vibration is infront of the cat, in the manifold downpipe, which is a supersprint one.
im a little lost. it annoys the hell out of me. changes tone depending on whether cold or hot, and depending on gear, and only seems to be coming from the left hand side of the car, which made me think it was a blow.
really wanting some suggestions as to what to do. would heatwrapping absorb some of it? what can i do? the exhaust has cost me roughly £1000 in parts, plus god knows how much in paste/sealant at £5 a time.
