his piston return springs are too powerfull, what he's hearing is the piston rods banging against the crank.


but yeah the reason i redid my exhaust was cuz the calmp that was right behind the flex bit rusted through and broke off, so it was just down pipe

 

as everyone said you probably have an exhaust leak....you could take this as a chance to get aftermarket exhaust

 

You have a leak mine did the same thing. No audis do not come stock sounding like that lol.

 

hey, ITS OK. i have samething!! people actually complement my car, cuz its not like aftermarket and its not silent.it has pure power sound - NOOOOOOOOAAAAAATTTTTTTTT
