there's a super annoying buzz coming from under the car after i installed my downpipe. anyone know what it could be? is it the downpipe resonator itself?

One: I have an anoyying buzz after a certain RPM. I have a header, test pipe, all the way back to a shitty APC muffler. It's just the exhaust resonating.

Two: My exhaust sometimes come in physical contact with the shield underneath the car due to the angle it was welded at. That makes a buzz two.

it's kinda wierd. my front brakes also sound like they're click against something when i'm on a hill and roll backwards with my foot on the brake.

check ur piping under your car like towards the front of the car directly under the center console of ur car there is a bend in there that could be rubbing against the body of the car

i found out what it was. the muffler i just put on has some sorta shield on it and it's buzzing on something.

arggg it's not the muffler after all. it's the downpipe itself like i originally thought. Is this something everyone else gets?
