Used for less than 300 miles on my 2017 Duke. Just found it a bit too noisy for my taste, though performance was noticeable in low RPM's in particular. Purchased new fall 2020 and in excellent condition. Easy bolt-on replacement removes stock pipe, cat and sound (pre-muffler) chamber.

Will need a piggyback ECU or similar to remap fuel delivery to achieve proper operation. Sticker states 2017-2019, but website shows through 2020 for this model # 16381CJ520

$350 for local pick up or let me know zip code for USA shipping rate. PayPal accepted. PM me or post below for details.

Yoshimura states: "When heading to the race track, everything counts, with either muffler option you lose half the weight of the stock system and gain 2.5% max H.P. and 3.3% max ft. lbs. of torque."

Check the Yoshimura site here for more details and installation instructions: 390 DUKE/RC390 17-20 Race R-77 Stainless 3/4 Exhaust, w/ Stainless Muffler
