wtf indeed, i have a question now..
my exhaust has a massive tin can buzz in it. it sounds like the noise is from the cat or fexi pipe? its pretty loud buzz aswel i thought by getting the twinloop muffler i wouldnt have this problem?

noise is only there under acceleration, and i have no resignator is that my issue?

Edit: im just so hoping that sound just needs to be worn in *fingers crossed*
