After thinking about it over-night, I realise that both Micmac & BillRoss77 have the 20/21 model N1K, so there is no ECU flash yet available. Please disregard my previous comments, and just but the slip-on muffler of your choice.If all you are interested in is an "improved" look & and "improved" sound, then just buy the slip on muffler. The Delkevic headers are just as restrictive as the stock OEM headers, so IMHO, you are just wasting money buying a full Delkavic system.
I would suggest that a Akrapovic headers + a Delkavic muffler is a better solution, but it will require a ECU flash. My suggested shop is BCPerformance in Sydney who did mine using Woolich software, or Ivans in the USA who uses his own software.
That is the one I went with as it is a very nice piece and the price is hard to beat. It also allowed me to use swingarm spools that would not work with the stock exhaust. My original plan was to go with Leo Vince black but it has been hard to come by as it has been out of stock for awhile. I am glad I went with the Delkevic as I think it fits the style of the bike quite well.Anyone have any fitment or quality experience on Delkevic muffler for the 2021 n1k? Specifically, I am looking at the 13.5" Titanium oval. I really like the Yoshi carbon fiber, but the Delkevic seems to sound pretty good and is close to half the price.

Did either of you look at or consider the 10" version? If so, why did you think the 13.5" was better?That is the one I went with...
The sound is just slightly louder than stock but it looks a heck of a lot better.
Fear not. The Delkevic components I've had were top notch and there have been lots of testimonials of folks on this forum to that effect. Just do a forum search for "Delkevic".I did look at quite a few on their YouTube channel. To me, the 13.5"/14" was the sound I liked best. I'm not big on super loud exhaust, as I am old AF and my hearing is bad enough already. Performance wise, this bike is so much more than what I am used to from my HD, I don't know that I need anymore power.
I guess my concern was about the build quality of the brand.
The stock slip on is unrestricted on the 2020. A db insert would actually be more restrictive and increase back pressure compared to stock.I myself prefer a long can to keep my bike quiet, capped with a dB insert to keep back pressure as similar to stock exhaust as possible, precisely because I don't care for a retune.
That is the case if you just change to aftermarket slip-ons. On a lot of bikes these days, that underbelly resonator chamber is the muffler, which is why I said what you install downstream of that won't make as much difference in the overall sound.The stock slip on is unrestricted on the 2020.

The fueling is perfect with the Delkevic slip on. Better than any other bike I have every ridden, which is a lot.
I bought the 14" CARBON FIBER OVAL MUFFLER TO FIT NINJA 1000SX (2021). It went on like a glove, fit perfect and looks/sounds great! With the baffle out, it is not too loud, but you can feel and hear it. The guys behind me say it sounds soooo smooth, especially with the quick shifting.Anyone have any fitment or quality experience on Delkevic muffler for the 2021 n1k?
