Magnaflow exhaust rattle at low rpm question....
I searched this but really didn't find an answer....anyways, I have a Magnaflow exhaust and when motor is cold or just started, at a low rpm (2000?) I have an annoying rattle vibration sound until I rev it up and move on....but it only does this when the motors cold, once warmed up it goes away.....anyone familiar with this? maybe a heat shield or mount...not for sure...any help is appreciated

Re: Magnaflow exhaust rattle at low rpm question....
Figured it out...crawled under the rig this evening and realized the gentlemen that installed my exhaust didn't put one of the clamps down on the flange so that it actually "clamped" them tight...he put it on too far back, therefore it wasn't doing it's job, so I loosened it and moved it down so it actually tightened them together..NO MORE RATTLE! ...anyways wanted to post this so if anyone has a similar problem, they have something to possibly point towards..
