We suggest to verify with your closest muffler shop. Thanks **Q: Will this feet on a jeep grand cherokee laredo 2012** A: It should as long as you get tge right diameter pipe for your exhaust. **Q: Will this fit a 2015 dodge challenger sxt** A: With a pipe bender, welder, and some extra 2.5" and 3" pipe, it's possible to make it fit your car. Mufflers like this are not an easy DIY installation. I recommend seeking advice from a custom exhaust shop to get what you want. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top Ware *by T***. on 9 December 2025* Top Verarbeitung und toller sound ### ⭐⭐⭐⭐⭐ Amazing *by A***A on 19 August 2025* ### ⭐⭐⭐⭐⭐ Pretty decent muffler but a tad loud for my liking *by D***N on 7 August 2023* ## Frequently Bought Together - Flowmaster 71419 FlowFX Muffler 3" Inlet/Outlet - Round Body - Moderate Sound 409 Stainless Steel - EVIL ENERGY 3.0 Inch Exhaust Clamp,Butt Joint Band Clamp Sleeve Coupler Stainless Steel for Pipes,Mufflers,Catalytic Converters 2PCs - 3" Inch Exhaust Clamps Stainless Steel Muffler Band Clamp for 3" Inner Diameter to 3" Outer Diameter Turbo Downpipe Tip Car System Connection (2 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/463757902-flowmaster-flow-fx-chambered-muffler-3-00-center-in-3](https://www.desertcart.co.uk/products/463757902-flowmaster-flow-fx-chambered-muffler-3-00-center-in-3) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
