Or there isn’t any back pressure with this mini muffler?** A: I doubt it adds much, if any back pressure. It is straight through with some mesh around where it bumps out. **Q: So is this a muffler or a resonator?** A: I would call it a resonator. It will round off some of the harsh sounds, but almost nothing to make the exhaust quieter. **Q: What is the outside diameter of the inlet? Description says inside is 2” but I’m needing the outside dimension please?** A: Mine was 2.25 **Q: Are the inlet and outlet id different?** A: -Inlet is 2.5” INNER diameter -outlet is 2.5” OUTER diameter -yes the inlet and outlet id are different ## Frequently Bought Together - TOTALFLOW 6644 Mini Race Exhaust Muffler | 304 Stainless Steel | 2.5" Inner Diameter Inlet - 2.5" Outer Diameter Outlet - EVIL ENERGY 2.5 Inch Exhaust Clamp,2 1/2" Narrow Band Muffler Clamp Stainless Steel for Pipes,Mufflers,Catalytic Converters 2PCS - EVIL ENERGY 2.5'' Exhaust Clamp,2 1/2in Lap Joint Band Clamp Stainless Steel for Pipes,Mufflers,Catalytic Converters (2PCS, 2.5 inch) --- ## 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.us/products/203310472-6644-mini-race-exhaust-muffler-304-stainless-steel-2-5](https://www.desertcart.us/products/203310472-6644-mini-race-exhaust-muffler-304-stainless-steel-2-5) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-24*
