Here is a video clip of a cold start the day after I added a Flowmaster Super 10 to my 2020 5.3 Silverado. All I had done was a muffler swap. Original pipe with mesh resonators is still in place. Sounds great and aggressive when accelerating and starting up but not too crazy when cruising. Haven't taken a long highway trip yet so not sure about drone on a long trip but I have been on short highway trips and the drone is very, very minimal, can't even hear it when music is playing.

Hey guys I'm new to the forum but I've been having some exhaust issues, and I'm hoping someone can help. I just recently swapped my muffler for the borla XR-1 (40085) muffler and deleted my resonator. I left the valve after the OEM muffler and then dumped the exhaust after the rear axle, no tip, just pipe. Ive been having an issue with a whistle or "whoosh" sound whenever I accelerate or whenever I have a warm start. I've gone to a shop to have them check the welds for leaks/gaps and there doesn't appear to be any issues and I still have the sound. Has anyone else had this issue with this model #? Could it be a defective muffler? Also, would adding an exhaust tip to the dump after my axle fix this issue? I'm open to all options at this point since it's not a leak like I was thinking. Thanks,
