This muffler sounds pretty good, deep rumble, not thin or raspy. It's been on my truck for 2 winters (salt and de-icer exposure) and it still looks good. It has the typical Flowmaster drone but I don't think it's nearly as loud as I remember my previous truck with a Super 40 being. For the price it sounds pretty good and is holding up well so far. ## Features - Durable Fully Welded Bright 409S Stainless Steel for good looks and long life - High Temp Interior Sound Absorption Material Offers Great Sound Control - High Flow Straight-through Design for Great Performance - Moderate Exterior Performance Tone - Mild to Moderate Interior Tone ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08D9RVBBT | | Brand | Flowmaster | | Brand Name | Flowmaster | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.7 out of 5 stars 288 Reviews | | Global Trade Identification Number | 00090127088463 | | Item Dimensions | 63.8 x 25.1 x 10.9 Centimeters | | Item Shape | Oval | | Item Type Name | Flowmaster 71249: 3.0 Center In/Center Out, 4X9X18, Flow Fx Muffler | | Item Weight | 6.14 kg | | Item dimensions L x W x H | 63.8 x 25.1 x 10.9 Centimeters | | Manufacturer | Flowmaster | | Manufacturer Part Number | 71249 | | Material | Plastic | | Material Type | Plastic | | Model | 71249 | | OEM Equivalent Part Number | 71249 | | Shape | Oval | | UPC | 090127088463 | | Unit Count | 1.0 Count | | Vehicle Service Type | Car | | What Is In the Box | Flowmaster 71249: 3.0 Center In/Center Out, 4X9X18, Flow Fx Muffler | ## Product Details - **Brand:** Flowmaster - **Item Weight:** 6.27 kg - **Item dimensions L x W x H:** 63.8 x 25.1 x 10.9 Centimeters - **Material:** Plastic - **Vehicle Service Type:** Car ## Images ![71249 FlowFX Muffler - Image 1](https://m.media-amazon.com/images/I/71Ed2nc3u5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Affordable and reliable *by X***Z on 14 February 2026* If you’re looking for a good muffler to replace one that is worn out or rusted out, this is really a great muffler gets the job done and it amplifies the sound of your car ### ⭐⭐⭐⭐⭐ Great sound but not loud enough to annoy your neighbours. *by B***N on 25 April 2026* Installed in place of the stock muffler on an F150 with the Gen 2 Coyote 5.0L.
