I have a 2013 2LS.
I just had a shop install a magnaflow xpipe and GM performance exaust.
When the car is in idle it sounds great. When you hit the accelerator, you get some pretty loud vibration/humming noise, to the point where your ears feel muffled. Maybe I'm just not used to it.
From inside the car, it sounds like a Honda after someone adds a performance exaust. Kind of obnoxious. Maybe there's an opening near the weld points.
The only engine performance upgrade part I have is a K&N CAI Typhoon.

Going to take it back to the shop that installed it just to be sure the pipes are not making contact with the frame.
Any other ideas to what may be causing this ?
