Review: good deep sound - instal instead of rear mufflers on Challenger V6, got a good deep tone, not loud, no drone. this is what i wanted. Could be more rumble, but it is fine. More loud- more drone, had experience. Review: I have the Colt exhaust on my 2001 Grand Cherokee WJ that comes with 14" body, 9" wide single chamber muffler (a common size EVERYBODY makes). I liked it but over time I got fatigued with it's volume. If I was 21 I'd have probably left it. This Dynomax was a direct replacement for the (or any) 14" muffler. Almost bought the #17747 which is a 20" body of the same muffler and close to the oem size muffler. Glad I didn't because that would have likely been too quiet. This one is already hardly louder if any than stock but it sounds good all the time and at every rpm. Can also hold conversations and listen for other noises in the vehicle (it's a 24 year old vehicle, that's important lol). This is about as civilized of a performance muffler you're going to find. ## Features - Large internal flow tubes improve exhaust flow and reduce backpressure - Exclusive patented flow director design channels exhaust flow and eliminates turbulence - Fiberglass matting technology to absorb unwanted interior resonance while maintaining a mellow performance tone - Dyno proven to flow up to 700 SCFM - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00029J3BG | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #226,503 in Automotive ( See Top 100 in Automotive ) #59 in Car Center Mufflers | | Brand Name | Dynomax | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.5 4.5 out of 5 stars (337) | | Global Trade Identification Number | 00086387177313 | | Included Components | Per Item Description | | Inlet Connection Size | 3 Millimeters | | Item Dimensions | 52.8 x 25.9 x 12.2 centimeters | | Item Weight | 9.45 Pounds | | Manufacturer | Tenneco (Dynomax, Walker, Thrush) | | Manufacturer Part Number | DYN17731 | | Material Type | Alloy Steel | | Model Number | 17731 | | OEM Equivalent Part Number | 17731 | | Shape | Oval | | UPC | 086387177313 | ## Product Details - **Brand:** Dynomax - **Item dimensions L x W x H:** 52.8 x 25.9 x 12.2 centimeters - **Item weight:** 4.29 kg - **Material:** Alloy Steel - **Vehicle service type:** Car ## Images ![Dynomax Super Turbo 17731 Exhaust Muffler for Jeep Wrangler - Image 1](https://m.media-amazon.com/images/I/61X-6KwPGmL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good deep sound *by A***S on 23 February 2022* instal instead of rear mufflers on Challenger V6, got a good deep tone, not loud, no drone. this is what i wanted.
