Dynomax Cat-Back Systems 39516 Editorial Review
The Dynomax Ultra Flo 39516 Exhaust System Kit for Jeep Wrangler has generally received a warm reception among customers who appreciate its deep, throaty sound without excessive cabin noise. Users describe the installation process as straightforward, although many warn that removing the factory exhaust can be a laborious and challenging task. Newcomers who have managed to tackle the project report a completion time of roughly two hours, but advise coming equipped with specific tools and sometimes making modifications, such as cutting parts of the existing exhaust for easier removal and proper fitting of the new system. Many customers rave about the performance of the exhaust, highlighting its ability to deliver a low, grumbling tone that enhances the driving experience without being obnoxious. It's noted for its resonance that is particularly pleasant at startup and diminishes nicely at cruising speeds, which contributes to a more enjoyable ride. Compatibility with the Jeep's style is also frequently mentioned as a positive aspect, as it aligns well with off-road aesthetics while maintaining functionality. However, some issues have arisen regarding missing parts critical for installation, leading to frustration among customers who were unable to install the system without those components. Additionally, the exhaust's positioning was noted by some users as potentially problematic, as it hangs lower than the transfer case skid plate, raising concerns for off-road durability. In summary, Dynomax's exhaust system delivers on sound, performance, and aesthetic appeal while presenting installation challenges and occasional quality control issues. **
