5" Down Pipe-Back Full Exhaust Delete | GM/Chevy 6.6 Duramax 2017-2023

The Diesel Dudes is a family owned business in Montreal, Canada. Our mission is to serve diesel truck owners with high quality parts and software, while providing excellent customer service along the way. 

If you have any questions about our products, or if you are wondering what kit is best for your truck, please reach out. 

Since our inception, our entire goal was to answer any and all questions our customers have. 

We get it, tuning can be complicated, and getting it wrong can damage your truck. That's why we went out of our way to find only the best tuning options for each and every truck model and year, and when we couldn't find a good enough option, we made our own. 

That's right, while we are the authorized dealer for many tuning companies, such as GDP and Proven Diesel, our technicians make many of our tunes in house. 

So either way, we have in house technical support on all of our products, in case you get stuck on the installation. But our installation guides and videos should be more than enough to get you going. 

Just remember, if you ever have questions, just call us at 888-830-2588 and our team will help you out!
