guys i have got the most annoying exhaust vibration sound in the world. my truck has a 4 inch silver line exhaust. i just put a muffler delete pipe on it. before the delete pipe it would always make a vibration sound when i put the truck in gear and it changed the idle. when i put the delete pipe on i had to cut the welds on the original exhaust hangers. instead of rewelding the original one back on i put a hanger from auto zone on it ang anchored it to one of my bed rails on the bottom. when i did that it raised the exhaust maybe 3/8 of an inch and the sound quit. the damn screw on the hanger came out yesterday and the sound is back. any help? any ideas on what to do? o ya and i put a new screw in and it still does it Thanks i appreciate any ideas

 

check the system font to back you most likely have a spot rubbing somewhere. and when you moved it, you got it off where it was hitting at.

 

most times it will be rubbing on the tranny cross member

 

Or at the down pipe up next to the bell housing.

 

Might check the transmission mounts and motor mount while someone pulls it in gear. You'll find the vibrations . Just make sure the parking brake is set and wheels are chocked. I know it sounds stupid but anything can happen and it only takes one mistake. For instance a guy we have worked with for years, that's been around big jobs and was well trained in job site safety was killed by a truck moving less than 2 mph . It's sad but it happens.
