The only thing bad is that the band clamp has a tiny exhaust leak even after repositioning it a couple times. I ended up purchasing a regular exhaust clamp to stop it. A good trick to remove the old exhaust from the rubber hangars is to sprat them with a little WD-40 and then use a medium to large pair of slip joint pliers to squeeze them off.The exhaust has a nice aggressive deep sound. ### ⭐⭐⭐⭐ Very pleased *by J***D on June 24, 2024* Installation was straight forward. Most of the install time was spent cutting the pipe for my short wheel base application and sticker removal. All info for cut was clear in the instructions. Sound is great. You notice it under easy driving but isn't obnoxious. Heavy acceleration brings it alive and is pretty loud. Freeway speeds is very low noise (again it's noticable but not terrible) and will work fine for daily driving. All in all I am pleased. ### ⭐ Great product, terrible manufacturer. *by J***E on December 30, 2014* The Exhaust Is great, Dynomax however has the worst customer service I have ever had to deal with. I went with Dynomax mainly because of the price and a rebate offer at the time, I never received my rebate. Trying to get my rebate was a waist of time, the Customer service representatives I talked to were super rude and argumentative.It is an exhaust so it's function and install are simple. I have a 2008 tacoma access cab long box, I had to trim about 8-10 inches off the exhaust. The hardest part of the install is removing the rubber exhaust clips. I used WD40 and wedged a screw driver in to pry it off, the rubber clips have alot of play so don't worry to much about breaking them. The exhaust has a nice idle sound and does not make your V6 truck sound like a car from the Fast and the Furious at higher RPM's.All and all i really liked the product before i talked to Dynomax, I would hate to have an issue with one of Dynomax's products and try to get it resolved with a customer service of their caliber. Spend the extra money and buy from a manufacturer that is % 100 behind their product and company. I plan on looking for another Exhaust so I can get the Dynomax Logo off my truck. --- ## 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.us/products/28807892-ultra-flo-39447-exhaust-system-kit-for-toyota-tacoma](https://www.desertcart.us/products/28807892-ultra-flo-39447-exhaust-system-kit-for-toyota-tacoma) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
