i just put a corsa catback system on and i'm really happy with the way everything fits and looks, the problem is the sound? at idle everything is great, driving down the road i'm getting a grinding sound? took it back and was told it was coming from the weep hole. is that possible or could it be something scraping the axle or a bad muffler?
has anyone else had a loud weep hole problem?
if it is the weep hole, is there a way i can fix?


thanks,
rob

 

The over the axle pipe is probably touching the upper panhard rod or the floor board.

 

No grinding from mine. That was the old 10 bolt. The Corsa is relatively quiet at idle. But, go wot and it roars.
