Akrapovic Racing Exhaust System Yamaha FZ09 /  FJ09

Akrapovic is proud to introduce a stunning Racing Line exhaust for the Yamaha FZ-09. The FZ-09 is a bike with a strong focus on riding emotion and represents a new direction in sport-bike evolution. A bike designed to give homage to the darker and unconventional side of Japanese society can now be made even more mean, moody and exciting with the addition of Akrapovic's offering.

The Akrapovic Racing Titanium system is constructed from high quality stainless steel with a titanium alloy outer sleeve on the muffler body. A  ‘slash-cut’ outlet section has been designed to retain the narrow lines of the FZ-09 and has a removable baffle plate, which features three stylish exit ports. Peak power gain of 5.4HP at 9900 rpm and peak torque of 3.9lb-ft at 5000 rpm. Increased power-to-weight ratio with weight reduction of 5.3 lb compared to stock exhaust.

The Akrapovic Racing Carbon Fiber system, with its striking carbon fiber outer-sleeve and stainless steel headers, suits the naked design of the Yamaha bike and this exhaust will certainly bring the best out of the high-torque 3-cylinder engine that beats inside the heart of the Yamaha. Producing an extra 4.7lb-ft of torque at 5,150 rpms and increased power output of 6.8HP, the Racing Line (Carbon) will produce powerful and thrilling performance in everyday conditions, as well as help to improve the overall experience of the machine thanks to a weight saving 8.4lb from the original system!

The Akrapovic Racing Line has been designed specifically for demanding riders and represents an ideal balance between price and performance. The exhaust systems are dramatically lighter compared to stock exhaust systems and feature exceptional production quality and increased engine performance combined with pure racing sound output. The headers and mid-pipes are constructed of high-quality stainless steel conical tubes with precision handcrafting. A special process known as hydroforming is used in the manufacturing of the exhaust pipes. This process injects pressurized water into each tube to form the ideal shape for optimum exhaust flow without causing creases or compromising the strength of the steel.

Akrapovic Exhaust’s unique design enables them to obtain the maximum output for each specific model of motorcycle, while significantly reducing overall weight. It’s not just about peak power - Akrapovic exhaust systems deliver increased performance throughout the entire RPM range. Increased power and torque result in a much smoother ride. All Akrapovic exhaust system measurements are formulated on in-house computer-controlled flow benches.

The Racing Line is identical to Akrapovic’s top range Evolution Line exhaust systems, with the major difference being the material that is used for the headers and mid-pipes. The headers and mid-pipes of the Evolution Line are constructed exclusively of titanium while the Racing Line uses stainless steel.


  • High quality stainless steel headers and mid-pipes
  • No fuel remapping required, but for optimal performance RevZilla recommends use of a fuel controller
  • A combination of beautiful machine and hand welds
  • CNC machined muffler inlet cap
  • Optimized to maximize lean angle
  • All carbon fiber parts are produced in-house
  • Air-tight quality controlled production means your exhaust will be perfect
  • High-quality, silicon-shielded stainless steel exhaust springs

Akrapovic Racing Exhaust System Yamaha FZ-09 / FJ-09 4.7 5 43 43
Full Titanium System I bought the full titanium system for my 2016 FZ09, and love it. I removed the DB-killer before I ever started it up, so I don't know what it sounds like with that in. But without, it is extremely loud in a good way. I am used to having my bikes loud and prefer it. I find that it is much safer to ride this way. After the install, the bike would die on deceleration because it wasn't getting enough fuel. I don't know if anyone else has had this issue, but I figure I should include that. I had to put in a power commander and raise the fuel output to keep this from happening. I already had the power commander, and I wanted it to run as smooth as possible, so it wasn't a big deal. Side note: I highly recommend the power commander anyways. That being said, the exhaust without the DB killer is very close to too loud. Some will not prefer it, but I love it. Yes, it's very expensive. When you compare it to the cost of an M4, or some other cheap slip on, it can seem hard to justify. If you buy an M4, and never hear the Akro, you will probably always be happy with your M4. But if I pull up next to you with mine, you will be sad that you skimped and went the cheap route.

looks great but reserved sound high quality, install did not take long at all. love the look. sounds a lot more aggresive than stock pipes, but wasnt terribly loud. You can take the DB killer out on these pipes but once i actually looked up the process of getting it back in, it looks a little more involved than i feel like dealing with now. All in all great high quality product. August 16, 2016
install advice alright dudes this exhaust arrived at my doorstep today and I was stoked! unboxed it feverishly and marveled at the craftsmanship and quality of the welds and carbon fiber bits, this system truly is masterful. long story made longer, the 3 things your must heed very carefully while installing this setup is your LAMBDA or 02 sensor the stock copper crush washers (in the header ports) and the small carbon fiber strap they give you to secure the exhaust when the system is on.. Install was a breeze but like most excited installs you are bound to make mistakes as I did, nothing major but maybe you can learn from me. Unbolt the head pipes from each of the three cylinders ( i made a mistake here and did not disco my o2 sensor not thinking the stock exhaust weighs near 25 lbs.) this nearly ripped the o2 sensor wires out of the harness NOT GOOD) number 2 be sure that the copper crush gaskets for the exhaust do not fall out of the ports or youll not see it and forget it bolt everything up and see it on the floor and slap your palm to your forhead with frustration as is what I did. number 3 the strap that holds the exhaust has aluminum bungs that hold the bolt that mess with they eye, make certain that bolt is straight as an arrow or you will strip out the aluminum threads with the grade 8 bolt provided, this one lead to alot of cursing at the moon but I got it.. take your time, the install is 30 mins tops if you dont do what I did hope this helps, the exhaust wakes the bike up huge and its a head turner, its like an angry jumbo bee in a paper bag ready rip up enjoy :D ps. I knocked the finish because there were burr marks and sharpie cut lines on my setup no worries tho nothing major. July 28, 2016
Could be louder Don't get me wrong, this pipe makes my FJ-09 sound like it should have off the factory floor, I just wish it was a tad louder. I know you can pull the baffle out, but that sounds ridiculous. My only real gripe with this pipe was that it was advertised for fitting FZ-09/FJ-09 yet the instructions make no mention of having to remove the centerstand on the FJ. Removing it was easy enough, but getting that *%&$ing spring back on was a pain. July 19, 2016
Sounds great, looks great, and way lighter than OEM *Carbon Version* Install took maybe a couple hours, and I was being careful to not miss anything. Instructions were easy to follow. I could not believe my ears when I started it up. I left the DB killer in, and it is plenty loud. The sound is incredible, and you really can feel it. I saw a FZ-09 with the M4 slip on, and I was considering going with that one. My stock headers were discolored, and I ultimately decided to replace the whole exhaust. I couldn't be happier, and I haven't even had it tuned or blocked off the smog pump yet. It does pop a little on decel, but not too bad. I will take care of that soon. June 29, 2016
Do not waste your money I had this system professionally installed on my 2015 FJ-09. It is barely louder than my stock system. I mean not noticeably louder. Sent emails to the manufacturer and asked what might be able to be done to enhance the noise level...no response. No noticeable increase in performance only dynoed at 106 HP.... total waste of money Save your money not worth the expense. June 28, 2016
Best looking after market exhaust out there, in my opinion Straight forward, easy installation, Sounds great w/ DB killer left in. Not to loud, just a bit deeper than stock. I removed the AKRO stickers so it doesn't look so after market. More stealth looking too. I'm glad I chose this one. June 28, 2016
Great looking and sounding exhaust The exhaust is a breeze to install and sounds great. June 21, 2016
