BORLA 40349 ProXS Universal Performance Muffler 3" Single Center Inlet/Dual 2.5" Outlets 4" x 9.5" Oval x 19" Long Body 25" Overall Length Reversible Design T-304 Stainless Steel

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

Sounds pretty good. Mounted to a 2017 toyota sequoia platinum 5.7 v8. Before mounting this I briefly ran a muffler delete and quickly realized that was a mistake. The sound was really good on the outside but the drone inside the cabin was too much for me, especially at higher speeds. Hence, I purchased this to get a balance between the sound I wanted without the loud drone. This muffler gave me the aggressive tone and rumble I wanted from the start. The start up and idle sounds almost the same as the muffler delete but when you get going you really see where it makes a difference. Furthermore, compared to the OEM muffler on the sequoia, this is a big upgrade in sound quality and exhaust flow. This unit is smaller and has a straight pipe design inside meaning I could look through one end and see straight out vs the OEM muffler which was not a straight pipe design. Note: I am running an MBPR exhaust tip (3 in to 5 out), the stock pipes and resonator on my set up.

Great mellow rumble from my 5.3 Silverado. 00 drone. Running 1 in/2 out. Exiting behind the right rear tire. 90° turn down tips. No dirty looks from the neighbors yet so would seem I have struck the perfect note.

great sound with no drone noise at all.

This exhaust is on my 2012 Toyota Tundra Crewmax 5.7l. I used the factory pipes to save money. It is louder than factory than start up nice roar! Smooth idol noy really any noticable sound. Good tone if you get froggy and have a stomp. I can tell it definitely helps with the restriction that the factory muffler had. At 45mph cruzing at 1.5 rpm I'm getting 19-25 mpg that's a huge jump. But don't expect to get good mpg if you have a heavy foot this is normal driving in city will test highway and update later. Borla is the best!

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.

Installed on my 2016 Toyota Sequoia 5.7 V8. Sounds great, a little louder than stock, didn't really notice any performance gains. I also used a Borla resonator in place the factory resonator with a 4 inch tip out the back. Previous to this, I had a MF, while it sounded good, there was a lot of drone, and overall very loud- obnoxious for long drives.

The quality is great, but the sound is gonna be just a little bit quieter than you want… No drone at all.

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.

Great muffler You whont be disappointed with the seller or the product Sounds amazing 2022 ram hemi Very deep tone

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.
