I have a Two Brothers Exhaust off 2014 CanAm Spyder RT. It’s a Standard Carbon Fiber S1R with a extra tip that supposed to reduce the sound by 3-4db. Still a little to loud for me. I put less than a 1000 miles on it. Went back to stock. New the S1R was 599.98 and tip was 29.98 plus shipping. I’ll sell for 450.00 shipped lower 48 US only. Call Fred. 254-913-1286
