I just put my downpipe on and flash XPT stage 2. I checked everything under an car and nothing is rubing. But when i tapped my downpipe it sounded like there was something in it. The car is running fine but it is annoying and loud. Help guys, wut could it b?

grab a hold of the thing and shake it hard. I'd wager it will knock into your support frame on the bottom where it bends. This is common from helix/invidia downpipes.

Take a metal grinder and grid off some of that support piece. It won't harm anything and it will prevent the contact.

Its not touching absolutely anything. Im starting to think its my wastegate cause i needed 2 adjust it and after i was done i heard a rattle. AHHH. It doesnt stop, at idle it rattles, when i let got of the gas and it rattles but when i accelerate it doesnt. could this be my wastegate? It sounds like its right at the point where my turbo and downpipe meet. :confused:
