i get a slight buzzing noise under load around 2500-3000 RPM. All bolts are tight and I can’t locate where it’s coming from. Any ideas? Don’t know if it’s coming from the exhaust or loose bracket. Ita very minor and doesn’t happen every time. I usually drive with PSE on anyway and don’t hear it, but it’s irritating when I do hear it. .

tighten all your bolts and claps for exhaust.

Are you hearing it only with the valves closed?

I notice what I am assuming are my exhaust valves rattle under load in various conditions.

Check your license plate frame

This will sound odd, but, if you have a sunroof... check the wind deflector when your roof is in the closed position.

Are you running the OEM exhaust tips? If so, they may just need to be adjusted. When I first installed my system I was still using the OEM tips, and they were making a buzzing sound between 1-2k rpm. I loosened them up and adjusted slightly a few times, and the sound stopped completely. It took me quite a while to figure out that's where the sound was coming from.

Nice tip (pun intended)! Would have never thought to check those.

Good call.
