I had stainless steel flowmasters on my 2002 gmc sierra with a 5.3, and duel exhaust, I put long tube headers on my truck and it was so loud I was scared to drive it thanking I would get a ticket. I put this Bola on it and to my surprise it was much quite and so much better sound, I like getting on it just to hear it. Such a deep growl, sounds great.

I am completely happy with this muffler on my 2016 RAM Big Horn Crew Cab 4x4 with 5.7 Hemi engine. I had a muffler swap done with the 26 lb. stock muffler because I wanted a more open, natural tone.This muffler made a noticeable improvement in how the truck rolls. I am not having to herd the truck forward any more with the gas pedal and I am using more brake pedal than I did before to get stopped. The engine is able to get rid of the exhaust gases much easier now compared to stock. I have a K&N drop-in air filter and reccomend that too!I have not noticed any drone in MDS operation from 0-80 MPH. I do notice a nice, deep, satisfying rumble in town and on the highway. Notice in the pictures that you can see through the muffler from the inlet through the dual outlets.I was told by Borla customer service that this muffler would drone (even if I left the factory resonators on) and that I needed to spend over $1,000 on their catback system or leave my exhaust stock. I have $165 in this muffler swap including having it installed and welded and am completely happy. The muffler shop did need to flare my exhaust pipes 1/4 inch to weld them to the 2.50 inch outlets on the muffler
Greatful.

I didn’t expect such awesome sound and so happy! Excellent performance and great price. Perfect fit for my 2017 Ram Big Horn 1500 Crew Cab 5.7 Hemi. I needed other exhaust repairs done so I had the muffler installed at the same time. Easy peasy and much smaller than the 20 gallon size OEM muffler… LOL!

Deep mellow tone, well pleased. Fast shipping. Install was $125, adapters for in and out had to be made.

Just right IMO...No drone. Smooth growl from the VK56. It's not a super loud exhaust. But it is quite noticable over stock. Anything ever happens to it, I'll buy another. Mine has been installed on my 2018 Pro4X for 3yrs now. Still looks and sounds like the day it was installed. Perfect for that 32V Aluminum DOHC 5.6L V8 :)

Arrived on time, construction was up to par. The only reason I gave it 4 stars is because I was expecting a little bit louder, but it does sound good throughout the rpm’s. I’ve only had it on a day, so maybe it’ll get a little louder after some time. It won’t get you in trouble with the law, i can definitely get an inspection sticker with it, if you want loud this is not it. Can’t comment on drone yet, too early to tell.

Fit perfectly on my Raptor, has better sound deep V8 Rumble, sounds good with stock resonator. Very great price, and cheaper option to go with compared to ordering a full catback exhaust system. Borla Muffler always High Quality. Recommend for other Raptor owners with 6.2L engine

Got it installed on my 2022 F150 tremor 3.5 eco boost . It was the right inlet and outlet size. Muffler shop had to add a small piece of pipe because it’s shorter than stock but I knew that would be the case. Added a nice little rumble to the exhaust sound but not too loud and zero drone while cruising. Part of me wishes it was a bit louder but my wife is happy it’s not. Seems like a nice muffler for someone that wants a little exhaust noise but doesn’t want to piss off the neighbours

Installed on a 5.0 small block ford in my Ranger. Each bank probably has less than 4 feet of tubing total and this muffler really helped to quiet it down, despite being a straight-through design. If you are looking for a loud exhaust this muffler isn't it, but it gives a nice deep tone and gets pretty loud when you step on it.

Nice fit and finish and well constructed. Moderate sound, with my Chevy big block it has a nice rumble at idle and opens up when you get on it. Have not noticed any drowning noise when cruizing.

Looks good, sounds great on 2021 ram 1500 classic hemi. You can hear it in the cab when you hit the gas, but barely hear it under normal driving and on the highway.
