Borla 40086 XR-1: High-Performance Stainless Racing Muffler for Sports Enthusiasts Review

Exactly what I expected. Put it on a 2021 Ford F-250 7.3L and it sounds like a real truck! Not too loud, but not quiet either. Perfect.

This muffler makes a lot of noise in the cab of my 2015 6.0L Chevrolet Crew Cab. Almost to the point of buying another muffler for my truck

Fits my 2010 Chevy 2500hd. Sounds amazing. Bold and loud. But still pretty much idle. Only gripe is that the drone in the cockpit at RPMs around 2000 RPM not doing well Love it even though people hear you!

My son wanted this for his 2019 Dodge Ram 2500. He wanted his truck to sound louder. This muffler did just that, but waking your neighbor up loud isn't crazy. It has a nice rumble, like my old Corvette. I love the sound of his truck!

Great exhaust for the money! Looks good, sounds good, great rumble that's not particularly loud on my 2007 GMC Sierra Denali 6.2L V8 Truck. My only complaint is that I wish it was made to clamp down, I had to do a bit of tweaking to get another wise great muffler to work!

I think it's perfect. Very aggressive, loud but not too loud. When you get in you know it's there, but it's quiet when you're on the freeway. I left the resonator and simply replaced the muffler and added a chrome tip. I hear something confusing, but I can't tell if it's a spike or a resonator. Overall great product and great sound.
