View Full Version : exhaust sounds

i have a custom magnaflow exhaust but at idle when it's warmed up it makes a bad ratteling-vibrating noise. is it possible a leak in the pipes? the thing is when i first start it up and the engine is cold it doesn't make that sound. i was gonna have someone look at it soon but i was hoping someone on here would be able to help

The pipes expand when hot and something is hitting.
