Exhaust Burble or Burp Sound During Acceleration

[Speedy3]

I was just wondering if anyone else has heard a "burble" comming from the exhaust when accelerating at WOT, right after shifting from 2nd to 3rd. At first I thought it was a backfire, but it sounds less intense and more like a muffled burp or burble sound. It only happens once right after shifting and pushing the accelerator back down. It seems like the turbo is spooling up right when it happens.

Someone told me that this is kinda normal with turbo cars.Im not sure why but mine does it sometimes also.

yea my car does it all the time when in low gear aroun 2k-2.5k rpms give it gas and let it go around plazas and s***...i think normal because turbo and after a while the exshaust gets smaller cuz build up...plus the turbo and back pressures

Mine did this the other day, though a little louder than what you described cause it scared me.

Ok, this is good then. I feel better when other people experience the same symptoms. Maybe the CAT-Back Exhaust will open things up a little more and eliminate this pressure harmonic.

yea it will at first but eventually the exhaust build up will get to a certain point and probably make the same noise...
