Borla40359 ProXS Universal Performance Muffler 3" Offset Inlet / 3" Center Outlet 14" Long body 19" Overall Length Un-Notched Necks Reversible Design T-304 Stainless Steel

good deal an product..cut out alot of the drone in cab when i was running flowmasters,,nice decent rumble at idle...an nothing too loud or obnoxious when u step on it but u know its there...perfect for me...

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!

This Borla muffler outshines my old Flowmaster on my 95 Chevy K1500 Silverado 350 engine. It is quieter than the flowmaster, however I think in time it will open up a little. In my first city/highway drive it actually seems to run smoother than before and maybe with crossed fingers a tad better mileage and power. Time will only tell! The sound is really nice and not annoying. This is our third Borla purchase as our first two are on our 73 C10 350 that has headers with 3” out to the dual Borlas and surprisingly it is much quieter than we thought. Sounds truly awesome. If you want more noise pick a different version but this style is great. They look so nice and our hopes is they last for many years to come. We have more Chevy trucks in the family that will be needing exhaust coming up and Borla will be our go to brand!

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

Everything's good

Hope these sound as good as they look. They look well made.

I have an 04 gmc sierra 1500 with a 5.3 liter v8. I was worried that the sound would be too loud because the borla muffler is much smaller than the factory muffler, and the borla has a pretty much straight thru design. My exhaust pipe is 2 3/4 and this muffler is 3 inch, so after making my cuts there was a small gap to fill. I used two 6 inch long exhaust adapters which I could sleeve to any depth which made up for the shorter muffler size.after installing the new muffler, I was very satisfied with the sound. Its a nice deep low sound which doesn't drone out on the highway. I can listen to music on low volume and not even notice it. However, when I romp on it, it puts out this low tone, throaty, almost shredding noise yet it doesn't carry all over town and echo off of buildings like you see on other trucks.It provides that very traditional borla noise that I was hoping it would, and for the price I would definitely buy it again. This is my second borla product and I am very satisfied with the results. Hope this helps!

Reduces drone while still sounding good
