Fitted my decat the other day which sounds great! But I’ve noticed what sounds like rattling during cold start and when pushing on coming from where the decat is. V bands are correctly fitted and tightened as well as exhaust bracket. Anybody had similar issues before? Also I never got a gasket with my decat and there wasn’t one on he original downpipe, am I supposed to have one? Also a slight chance it could be a blowing sound but not sure and I really can’t be bothered taking the decat back off again to check as it’s a pain in the tits as some of you may know!
