Customer Reviews
Let me start off by saying you guys nailed it. Everything lines up perfectly and I couldn't be happier with the results. Adds a little more noise then the stock pipe, which was very quite, but not too much. It attached to the bike perfectly nothing was too loose or too tight. Who ever built it knew it would fit thats why they put the label on it. Again I cant thank you enough.
Easy install. Quality sound and look! I love it! It sounds better every time I ride my bike.
Easy install. Sounds excellent. Video attached is on a stock 2021 KTM Duke 390 with the baffle removed. Baffle removal was easy.
I purchased for my duke 390 2021 model in August hoping it would fit sadly it did not.Wasn't a problem emailed Steve Coffman and was answered personally advised that they were in prototype mode for 2021 model imagine that an owner answering his customers emails this company is by far the best all around for any purchases I have made in years.They shipped out the newly fabbed 2021 model within days and fit perfectly and sounds incredible with all baffles in place plan on removing one of the three due to a lot of terrible drivers in my area in hopes of a much louder exhaust note. It is with my whole being that I recommend this muffler and better this company.You will not be disappointed with quality or service my only question or request is could Coffman offer an orange anodized tip for us KTM owners with serious OCD issues lol....!!!!
Looks good, sounds good. Easy install.
