Akrapovic Slip-On Exhaust Kawasaki Ninja 650 R / ER-6N

Our sporty and lightweight SLIP-ON systems offer a great balance between price and performance and represent the first step in the exhaust system tuning process. The muffler outer sleeve is made of titanium, which gives a special hi-tech touch to our SLIP-ON SP Series system and reduces overall weight by 4.51 kg as it is not EC Type approval and dedicated for racing oriented riders.

Power & Torque: the exhaust system modification with the SLIP-ON system results in a major boost in performance, delivering a usable 72.3 HP at 8900 rpm on back wheel. But the increased power isn’t available just at the top of the range; the system shows its quality already from 2000 rpm up through entire rpm range. The maximum power increase between the Akrapovic and the stock system is 5.2 HP at 5280 rpm. Additionally, the torque is substantially higher in the lower rpm area at 3000 rpm and in the middle of rpm area.

i liki After several months of deliberation, I finally decided to buy the Akra slip-on for my 2011 Ninja 650R. I was surprised how light this thing is - just a few pounds compared to my stock unit that is easily 20+ pounds. It is a very nice addition to my bike - the materials and workmanship are top-shelf. The instructions for the install did not match my bike exactly, and there were a few superfluous steps (loosen bolts on headers only to re-tighten them later), so it took a bit longer to install that I anticipated. I think it would be almost easier to just install the thing without any instructions. It's a somewhat tight fit on the bike, and I was really wondering if it would actually fit, but it did with one small exception: The bottom corner of the fairing was resting - pushing actually - against the unit when it was all installed - right on the sticker. I knew that the pressure of the fairing on the exhaust wold wear off the sticker, and possibly melt the fairing, so I dremmeled off a part of the fairing. See the pic below for details. A few months ago, I cut off the fender extension with my dremmel as well, so I was not concerned about making some customizations. I'd like to think that a pro installer could have made it work perfectly; but like I said - I did not really care about making the modification. It has a dampener you can unscrew and pull out. The sound is amazing! However, I'm unable to determine if there really is a performance increase. June 17, 2013
