## 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.

### ⭐⭐⭐⭐⭐ Borla muffler has the best sound
*by A***R on December 2, 2025*

great sound with no drone noise at all.

### ⭐⭐⭐⭐⭐ Gives off that aggressive sound without drone
*by S***N on July 11, 2025*

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.
