## Description

Borla Pro-XS 3", 2-1/2", 19" x 9-1/2" x 4" Oval Cen/Dual Turbo XL Muffler

Review: Nice upgrade to 2016 RAM with 5.7 Hemi - 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
Review: Gives off that aggressive sound without drone - 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.

## Questions & Answers

**Q: Is the inlet and outlet 3”?**
A: No, this is either 3” in and dual 2.5” out or dual 2.5” in and 3” out. There is someone named Larry saying this isn’t a reversible muffler, but he is wrong, I asked Borla!

**Q: Anyone know if this muffler is the correct size inlet and outlet etc for a direct replacement in a 2017 gas Nissan Titan?**
A: Got it on a 2014 Silverado

**Q: What type of metal is it made of?**
A: Stainless Steel 1,000,000 mile warranty

**Q: Is the 40349 by borla the pro xs?**
A: Yes. I put it on my Ram 1500 5.9L v8. I previously had 2 flowmasters and they don’t last long before they rust out. The sound is better than the flowmaster and it is quieter at cruising speeds. Borla definitely has my business for a system on my new Silverado when it is time.

### ⭐⭐⭐⭐⭐ Quality built/00 drone/powerful rumble
*by T***Z on June 5, 2025*

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.
