Hey all, I just got my borla TD catback installed, and now driving im noticing that when im in first gear or reverse (like as I accel into it) I am getting a shaking/rattling sound from the exhaust. None of the other gears do it, and I can't hear anything on bumps or anything like that. Any ideas as to what may be the problem?

Thanks.

 

I'm guessing it's your sway bar rattling on the right side exhaust piping. I know when I installed mine it had to be spaced and twisted just so to clear the bar. In fact, mine is not spaced and twisted just so, and at around ~2k rpm and decelerating I get a rattling/grinding noise. I need to put my car back up on a lift, loosen up that section of piping, and twist it around so it can adequately clear the sway bar. Just my $.02
