Damn vibrations! My Beautiful SS runs strong EXCEPT I'm getting these nasty vibrations from what seems like behind my car around where my exaust pipes end!? No rough idle, no loss of power, runs fine but when I'm close to 1000 rpm, it sounds like a HUGE mutant bee is sitting on my trunk.. It stops when I'm over 1500rpms tho. Or at least the engine drowns it out by then.

not really, i notice it stops as soon as i leave the 800-1k rpm range. (idle) im really thinking its the exaust pipe rattling against something. its really annoying. my car is too low to do anything so im kinda limited as far as getting under it. i can get a lift but shop isnt open until wed.

hah glad to toss a laugh your way sweep..
but back to the rattling, i was talking to another LS1 driver at the gas station yesterday and he said that the resonating chamber wields in my flowmaster could be deteriorating causing everything in the muffler to rattle. My next muffler will proabably be a MagnaFlow or SLP loud mouth unless you guys think otherwise? BUT before i spend $$ im going to check that axle to see if it is hitting. if it is, what should i wedge in between that wont melt or fall off?

Yeah it could always be the "death rattle" in your muffler. I had a custom chambered flowmaster on my car when I first bought it and after a few months it rattled like ****. Bullet muffler is the way to go 
Hope you get it fixed

Thanx for the help guys, turns out it was an exaust pipe weld that broke and two pipes were vibrating against eachother. Just tapped it with a arc welder and was good to go! thank got i didnt have the rattle of death. If i did, i would have just went and bought new exaust all together.
