Rep Power: 778

ok guys as i go through life with my SS i have noticed that when lets say i am at the track and im doing my burnout or i am reving and my rpms drop to about 2 grand there is a horrible rattle sound coming from my exhaust (stock w/ cutout) and i have also heard this from other f-bods as well, anyone else experience this??

probably a heat shield unless you like to sit and idle then could eb the internals

yeah i thought i was the cats, but the other day i removed my Ypipe and checked both of them they are not coming apart, then i thought it was my 02 sensers.....but **** i dunno i hate that sound

check the heat shields that bolt (or rivit) to teh body

yeah and my rear muffler hangers could be bad...i mean the rubber part is worn on mine so the pipes rattle a bit.

Best way to solve that problem is to remove the cat.

not if it's the heat shield

If your thinking of the same thing I'm thinking of then it should be removed as well once the cat is replaced with a stright pipe.

i had this same problem with my exhaust system, mine used to rattle at idle, real bad. I had checked all heat shields and I even took it to a shop they couldnt find anything. So i just ended up get a pair of headers with an ORY and that solved my problem!

the one heat shield is hooked to the body

I'm not sure about F-Bods, but in Y-Bods an X-Pipe fixes that. (assuming its not a heat shield or the cat)

Agreed...... but before you remove them, be sure to check your muffler bearings.

While your under the car might as well check the rotor bearings too.

make sure the blinker fluid resevoir isn't leaking
