Sounds great!
Perfect sound with all straight pipe from motor. Execution on design is flawless when connecting to mid pipe and bracket!! I had a cheap amazon china muffler and I can finally feel the backpressure needed! A++++
It sounds absolutely amazing. The tone for my
KTM RC 390 is just what I was hoping it would be. Down shifts growl and pop.
Alright, so I received and installed the exhaust yesterday. I took it for a ride today and it sounds absolutely amazing.
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....!!!!
