I currently have a 2021 GMC Sierra 1500 denali w/6.2L. I am planning to upgrade the exhaust, keeping the stock rectangular outlets. I am trying to decide upon the GM Perf cat-back 84964744 or the Borla s-type cat-back 140773. Are there any drone or other issues with either of these systems when the truck goes from V8 to V4?

I have the Magnaflow cat-back on my 2020 with the 6.2. Nice rumble and little to no drone. Have thought about changing to the Borla but don't think it will make a significant difference. Not worth the work just for more sound IMHO.

Good luck with your decision. :cool:
