Customer Reviews
I love the way the blacked out exhaust looks. Sounds great and I’m definitely happy for the I spent. I will say the only thing I’m wondering is if I was suppose to get a black clamp since I’m pretty sure I seen on thier page that all “black out” exhausts come with a black exhaust clamp but I could be wrong
I installed this exhaust about a week ago and I love it. I got help from the support team to make sure it fit my bike. I wish it was a little louder so I may end up taking out the baffle, but for now it is just fine.
Please make it clear that this exhaust is for the Generation 2 Duke 390 and will not fit the 2024 model. I will look for your Generation 3 exhaust when it gets developed.
This exhaust looks very elegant and minimalist compared to the bulky stock exhaust on my KTM Duke 2022.
I've bored out the baffle (db killer) in my stock exhaust and will say the Coffman exhaust is slightly on par in loudness in comparison and that is with the baffle inside the Coffman exhaust. Running the Coffman exhaust without the baffle sounds just a little quieter than having no silencer at all on this bike.
The exhaust sounds good, looks great, and got here quick.
