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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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. 90Β° 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. ## Frequently Bought Together - 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 - EVIL ENERGY 2.5 Inch Exhaust Clamp,2 1/2" Butt Joint Band Clamp Sleeve Coupler Stainless Steel for Pipes,Mufflers,Catalytic Converters 2PC - BORLA 40358 ProXS Universal Performance Muffler 2.5" Offset Inlet / 2.5" Center Outlet 4" x 9.5" Oval x 14" Long body 19" Overall Length Un-Notched Necks Reversible Design T-304 Stainless Steel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/81801843-40349-proxs-universal-performance-muffler-3-single-center-inlet-dual](https://www.desertcart.com.kw/products/81801843-40349-proxs-universal-performance-muffler-3-single-center-inlet-dual) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
