I received my first delivery of Akrapovic S-Y2SO11-AHCSS slip-on exhaust systems for the 2015 Yamaha R3 yesterday (it’s the same as the R25 exhaust), but I ran out of time to post about them, so here it is… Packaging is simple and the exhaust is marvelous! I would expect nothing less from Akrapovic. The welds and seams are beautiful. It features a stainless steel pipe with the most minimal “muffler” ever, and a slick titanium outer sleeve and mounting tab. It’s basically just a straight pipe as you can see looking down it. It truly looks just like the Yamaha M1 exhaust, I couldn’t be happier! 🙂
The other thing that makes me very happy, is the inclusion of a big carbon reducer bushing to mate it to the stock headers…why does this make me happy you may ask?? Because it means that Akrapovic is planning to release a separate header that will mate up with this already oversized slip-on, YAY!!! (I confirmed this with my Akrapovic rep) No reason to wait for the full system, now we can just get this awesome looking and sounding slip-on, and replace the stock headers later as the new headers and fuel management systems becomes available. Awesome. Way to go Akra.
As for the numbers, Akrapovic’s website claims 6.2 lbs for the stock exhaust, and 2.0 lbs for this slip-on. On my scale, I see 2 lbs .4 oz with the bag of hardware, and without the reducer sleeve, BAM!!! 1 lb 15.4 oz. Under 2 lbs, not bad.
You can check out the sound difference between the stock Yamaha R25 and with this Akrapovic Slip-on exhaust here on Akrapovic’s website. It has a wonderful growl, I can’t wait to actually have a bike here to install it on, lol.
