I just installed a budget/lss b-pipe with a resonator on my 02 6spd. Its not loud at all but when I rev I hear a rattle as the rpms drop. I tried moving the exhaust around and got no rattles. I was wondering if it could be the flaps in my stock muffler making the sound as its backfiring a little. Its not a loud rattle but just wasnt sure if that was a common thing. Second question..... Are the only 2 rear sections available the stillen/hks and cattman? I was either going to get a rear section or have an exhaust shop fab one up with a magnaflow. I tried searching for rear sections and those are the only 2.

 

bump????????
