Review: تم التركيب على سنتافي ديزل الصوت طررررب ومناسب جدا ماهو مزعج ابدا Review: Sounds good. Light weight. Easy install for a welder or exhaust shop. Saves around 80lbs over my stock lexus gx470s huge muffler I replaced it with. Its still relatively quiet but sounds good when you get on it. No drone at any speeds for me. It also feels like I gained some power. Easy upgrades. ## Features - 409SS Stainless Steel Construction - Aggressive Sound - Flowmaster Chambered Technology - Premium Quality - Easy Installation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003BZ7ME8 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #13,024 in Automotive ( See Top 100 in Automotive ) #1 in Car Rear Mufflers | | Brand Name | Flowmaster | | Compatible with Vehicle Type | Car | | Configuration | Offset/Offset | | Customer Reviews | 4.7 4.7 out of 5 stars (2,506) | | Global Trade Identification Number | 00700042023929 | | Included Components | Flowmaster 842518 Super 10 Muffler 409S - 2.50 Offset IN / 2.50 Offset OUT - Aggressive Sound | | Item Dimensions | 16.5 x 24.1 x 10.2 centimeters | | Item Type Name | Flowmaster 842518 Super 10 Muffler 409S - 2.50 Offset IN / 2.50 Offset OUT - Aggressive Sound | | Item Weight | 5.25 Pounds | | Manufacturer | Flowmaster | | Manufacturer Part Number | 842518 | | Manufacturer Warranty Description | 10 Year Limited Warranty | | Material Type | Stainless Steel | | Model Number | 842518 | | OEM Equivalent Part Number | 842518 | | Outlet Connection Size | 2.5 Millimeters | | Part Interchange Info | 842518 | | Shape | Oval | | UPC | 700042023929 | | Unit Count | 1 Count | ## Product Details - **Brand:** Flowmaster - **Item dimensions L x W x H:** 16.5 x 24.1 x 10.2 centimeters - **Item weight:** 5.25 Pounds - **Material:** Stainless Steel - **Vehicle service type:** Car ## Images ![Flowmaster 842518 Super 10 Muffler 409S - 2.50 Offset IN / 2.50 Offset OUT - Aggressive Sound, Black - Image 1](https://m.media-amazon.com/images/I/61mk4Ua5LfL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***. on 17 April 2021* تم التركيب على سنتافي ديزل الصوت طررررب ومناسب جدا ماهو مزعج ابدا ### ⭐⭐⭐⭐⭐ Review *by T***M on 2 May 2025* Sounds good. Light weight. Easy install for a welder or exhaust shop. Saves around 80lbs over my stock lexus gx470s huge muffler I replaced it with. Its still relatively quiet but sounds good when you get on it. No drone at any speeds for me. It also feels like I gained some power. Easy upgrades. ### ⭐⭐⭐⭐⭐ Review *by B***Y on 8 January 2026* This exhaust is awesome. It took my nissan frontier v6 and made it sound like a completely different truck I'd recommend it to anyone looking to make your truck down right sound mean. I've had it on the truck for about 2 weeks now and am loving the change. The deep rumble is so satisfying while driving and it definitely opened up a little power. ## Frequently Bought Together - Flowmaster 842518 Super 10 Series Chambered Muffler - EVIL ENERGY 2.5'' Exhaust Clamp,2 1/2in Lap Joint Band Clamp Stainless Steel for Pipes,Mufflers,Catalytic Converters (2PCS, 2.5 inch) - EVIL ENERGY 2.5 Inch Exhaust Clamp,2 1/2" Butt Joint Band Clamp Sleeve Coupler Stainless Steel for Pipes,Mufflers,Catalytic Converters 2PC --- ## 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.ro/products/253442963-flowmaster-842518-super-10-muffler-409s-2-50-offset-in](https://www.desertcart.ro/products/253442963-flowmaster-842518-super-10-muffler-409s-2-50-offset-in) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-04-24*
