Got a new cat back by pro tuning(complete ****, said bolt on but wasn't) it sounds great in neutral, i can rev it up to limit with no rattle. But as soon as i put it in drive i get a rattle when it goes over 2k rpm.
I have no idea why and this is crazy annoying. Please help with any suggestions. Currently not running a cat(it is legal in my area).
