    • Quite
I would only use this muffler if you plan to cut your cats off or running long tube headers to give it a nice sound, otherwise it’s too quite.

    • NO DRONE!
Great muffler for my Chevy 5.7 V8. As per the headline, absolutely no drone whatsoever throughout the entire power band. I could barely hear myself think between 40-70 mph with my prior setup (local generic muffler install.) Nice throaty tone, not too loud, and definitely not the muffled stock sound. I wouldn't hesitate to recommend this Borla to anyone given my experience! ... show more

    • Bad drone in 2023 Suburban 5.3
Sounds good but bad drone at 1800-2200 rpms after I replaced stock single exit muffler in 2023 Suburban 5.3.

    • Quiet!
I changed from a flowmaster to the borla because of the drone in my truck. It was horrible. The borla made a huge difference.
