Borla Stingers question/issue?
Just had them installed on my C5 z06 along with an X pipe. At a specific RPM range(not sure what range, need to look)), I get a "buzzing" noise inside the cabin, almost as if the exhaust is vibrating/hitting somewhere. It's not drone. Could this be normal interior resonance?
Thanks

After a closer look, it happens between 2-3K RPM's when hitting the gas(in gear). Definitely sounds like it's coming from the passenger side. I think something needs to be adjusted.

Check for alignment of the xpipe near the gas tank metal heat shields. My XS Power xpipe was a bit closer to the drivers side than the passenger side and it would put off a slight buzzing vibration at a certain RPM as well. I had to do some fine tuning of the install and push the heat shield out of the way a bit.

I have Borla S-Type II mufflers on my '01 coupe and have the same problem. Around 2.5k RPM when the car is warmed up there is a buzzing coming from the drivers side that is definitely resonance related. I have not been able to eliminate it or pin point it. At first I thought it was the heat shields, and it still may be, but I tried bending them and contorting them such they they held a different shape with no luck.

Buzzing
Apologies for waking an old thread, but was there any conclusion to this? I'm having exactly the same issue, C5 coupe with Borla S-Type II, loud resonating / buzzing noise between 2.5k and 3k rpm. Really annoying, and quote vocal outside the car too. It sounds metallic, so I'm wondering whether it's the Borla muffler itself. I also checked heat shields and there's plenty of clearance there.
I'm going to mount a camera with speaker near the exhaust tips to see whether it's more 'back there'.
