Now available in a round body, these straight through style mufflers feature a 409S stainless steel case and the quality you would expect from Flowmaster. Features Straight through design Durable fully welded 409S stainless steel case Moderate exterior performance tone Flowmaster quality Please Note: Universal Muffler - Not a direct fit. Some adaptation required. Review: Amazing sound - Had an exhaust shop put one of them on my wife's wagon. It really gives it that classic muscle car sound. Only droning that shows up is while accelerating but while at cruising speed virtually none! Review: Nice, but louder than expected :) - They are loud and more so than expected. I went with the glass pack style to gain clearance on the vehicle, that worked. Was surprised as to how loud they are on a stock old 6 cylinder truck. OMG if I put them on my muscle car V8 with a good street cam. fit and finish looked good. ## Features - Fully Welded 409S Stainless Steel Case - Moderate Exterior Performance Tone - Straight-through Core Design - Compact Design - Package includes: 2x FlowFX 2.25" In/Out Round Body Muffler ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BGZ3B7G2 | | Best Sellers Rank | #110,582 in Automotive ( See Top 100 in Automotive ) #90 in Automotive Replacement Exhaust Mufflers | | Brand | MAPerformance | | Brand Name | MAPerformance | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.6 out of 5 stars 126 Reviews | | Item Dimensions | 21.7 x 4.8 x 4.5 inches | | Item Weight | 6.26 Pounds | | Item dimensions L x W x H | 21.7 x 4.8 x 4.5 inches | | Manufacturer Part Number | 71415-2 | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model Number | Stainless Steel | | OEM Equivalent Part Number | 71415-2 | | Part Interchange Info | 71415-2 | | Shape | Round | | UPC | 675505443135 | | Unit Count | 1.0 Count | | Vehicle Service Type | Car | ## Product Details - **Brand:** MAPerformance - **Item Weight:** 6.26 Pounds - **Item dimensions L x W x H:** 21.7 x 4.8 x 4.5 inches - **Material:** Stainless Steel - **Vehicle Service Type:** Car ## Images ![Flowmaster Flowmaster FlowFX Muffler (2 Pack), 2.25 In/Out - Round Body - Moderate Sound by MAPerformance - Image 1](https://m.media-amazon.com/images/I/71aiU7BYODL.jpg) ![Flowmaster Flowmaster FlowFX Muffler (2 Pack), 2.25 In/Out - Round Body - Moderate Sound by MAPerformance - Image 2](https://m.media-amazon.com/images/I/513udJNuHoL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing sound *by D***A on March 2, 2026* Had an exhaust shop put one of them on my wife's wagon.

I went with the glass pack style to gain clearance on the vehicle, that worked. Was surprised as to how loud they are on a stock old 6 cylinder truck. OMG if I put them on my muscle car V8 with a good street cam. fit and finish looked good. ### ⭐⭐⭐⭐⭐ Great Quality mufflers at a fair price *by H***R on January 3, 2025* I heard sound clips on You Tube and I was down to two choices this was one of them . I'm not disappointed I'm Running them on a Ford 390 PU with no Cats they are not to loud not to Quiet . They sound better with Tailpipes instead of dumping a turndown right out of the muffs I also installed a H pipe in the system the Mufflers have a stainless type finish and look High quality made its basically a glass pack with a large body . ## Frequently Bought Together - Flowmaster Flowmaster FlowFX Muffler (2 Pack), 2.25 In/Out - Round Body - Moderate Sound by MAPerformance - EVIL ENERGY 2.25 Inch Exhaust Clamp,2 1/4" Butt Joint Band Clamp Sleeve Coupler Stainless Steel for Pipes,Mufflers,Catalytic Converters 2PCs - TECTRUC Exhaust X Pipe 2.25 Inch Inlet,Stainless Steel Universal Exhaust X Pipe 2.25" Inlet 2.25" Outlet 12" Long for Smoother Exhaust,Dual 2 1/4 Inch Crossover X Pipe Exhaust Tip --- ## 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.ie/products/546053810-flowmaster-flowmaster-flowfx-muffler-2-pack-2-25-in-out](https://www.desertcart.ie/products/546053810-flowmaster-flowmaster-flowfx-muffler-2-pack-2-25-in-out) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-07-04*
