Yoshimura R77 Race Exhaust System Yamaha FZ-07 

The Yoshimura R-77 Exhaust System was designed with the needs of the racer in mind. Using the feedback received from the Yoshimura Road Racing Team, their designers came up with a muffler that is constructed from lightweight materials, grants a significant boost in power thanks to its high-flow trapezoidal shape and gives your bike a great sound without being excessively loud.  When combined with the stainless steel headers and mid-pipes, the muffler will help your engine make even more power and reduce weight. The end result is a complete exhaust system that will let your motorcycle reach its maximum potential!

Features:

  • Superbike technology and styling
  • Trapezoidal-shaped sleeve
  • Large volume of packing material
  • Straight baffle for ample flow
  • Innovative end-cap
  • Stainless steel header and mid-pipe
  • Made in the USA

My experience with Yoshimura has been that it is a quality product for a fair price.

It fits my bike. I saw many videos on this system and they all had great reviews. It's past time to get this awesomeness. It wasn't the most affordable, and I sacrificed things, but I didn't trust any other seller to get it from. SO, here I go.

SEA Caliber on Mar 14, 2016
Yoshimura and Yamaha go hand in hand. Owned a Yosh pipe before for my '04 GSXR 600 and loved it. Keeping the tradition going with a clean exhaust setup. So far love the performance and looks in every way!
Geoffrey Y on Feb 26, 2016
After reading reviews of this system on revzilla I felt that this would be just what the doctor prescribed!!! Thanks revzilla
Ryan W on Nov 21, 2015
Great look, price, and preformance
Kyle H on Oct 27, 2015
Great reviews on fz07 site
eric n on Oct 10, 2015
To improve performance and mainly to improve sound and make myself more audible and thus visible to other motorists. Also, I wanted something different from the Akro that everyone wants and less expensive as well. The baffle is also removable, allowing for more variation in sound.
Jimmy B on Aug 24, 2015
Great sound, great value for the money
Miguel D on Aug 2, 2015
oem muffler not loud enough
Donald E on Jun 28, 2015
The awesome sound and price brought me here
Eric W on May 20, 2015
Did some research and liked the sound the best out of all exhaust I heard. Plus you cant beat the price

Christmas gift

i chose this exhaust system to replace the heavy stock exhaust with a lighter, great sounding and much cooler looking system
David B on Nov 21, 2014
Factory exhaust was too quiet. Now the sound is exhilarating, throttle response is smoother when transitioning on and off. Plus, now cagers can hear me approaching.

Does this exhaust have a catalytic converter? I live in California, will I get pulled over for having this exhaust? Has anybody in California purchased this exhaust? Thanks.
Tri N on Feb 3, 2015
BEST ANSWER: I've always ran race exhausts on all of my motorcycles in California for 30 years and never been stopped for it. Just be courteous and don't annoy people. Actually, I've never known of anyone riding responsibly to ever have a problem. Keep those revs low around populated places. This exhaust, without the baffle, is quieter than the pipes on my HD at low rpm.
Does this exhaust has a catalytic converter?
A shopper on Feb 3, 2015
BEST ANSWER: Sorry no catalytic converter...it's straight pipe other then the slip in DB killer
Will this pass emissions in Utah?
JeppMatt on May 8, 2016
BEST ANSWER: I asked this question but found out that Utah does not require emissions testing on motorcycles, only a safety test. Just thought I'd answer it for any others wondering.
does this come with headers or do they have to be purchased separate?
Mike D on Jan 19, 2015
BEST ANSWER: Hey Mike, these do indeed come with headers. Everything about this kit is top notch. No I'm am not paid for my reviews I just am so happy with the quality of this kit, you cannot go wrong with Yoshshi. I also recomend taking out the small rubber grommet out of the side of the muffler before you fully install it is really hard to get at it when its installed. I ended up tearing mine, but no worries Yoshimura will send you a new one for free. Hope I was a help, take care, Weston B.
Did you guys have to re-map your A/F ratio? I'm curious if the bike will run to lean without a re-map.
A shopper on Apr 19, 2015
BEST ANSWER: As I have not taken an AF reading just looking at the tail pipe I can tell it is running rich, also the smell is rich. My bike runs perfect without a tune with baffle in, although I cannot speak for with baffle out.
Yoshimura says with baffle in that a tune is not required, but I can imagine the bike could always benefit from a tune to squeeze out better throttle response as well as hp.
Does the FZ 07 full system come with a DB killer?

Does the FZ 07 full system muffler require repacking?
A shopper on Nov 18, 2014
BEST ANSWER: Not sure about repacking. It does come with a db killer, but its kinda a joke. With the db killer in, it is still ridiculously loud. Almost too loud. With the db killer, if you are half or more throttle, you will attract cops attention like crazy. I'm absolutely unable to ride without ear plugs and I have the db killer in. My last bike had a delkevic straight through exhaust which was loud but not nearly as loud as this beast!
Did you guys have to re-map your A/F ratio? I'm curious if the bike will run to lean.
A shopper on Apr 19, 2015
BEST ANSWER: I havent yet, if anything the bike seems to be running a bit rich/overfueling. Under 4k revs youll get the occasional popping of unburnt fuel in the exhaust, but above 4k it purrs like a kitten due to yamaha's fuel cut programming.

A fuel controller(dynojet's PC-V, Bazzazs' zfi, etc.) Is a very good idea if you intend to make any alterations to the engine whether its something as simple as an air cleaner, exhaust, or a full top end overhaul. I would certainly recommend getting one if you plan to upgrade the exhaust
So, I bought this system, and it's wonderful. That being said, I slid my motorcycle yesterday and the end cap took a beating so I need to replace it. Is there a slip-on that would fit the system for the FZ-07? Or do I need to buy it with the pipes and just toss them?
Michael L on Jul 6, 2016
BEST ANSWER: I would contact Yoshimura directly and order whatever replacement part you need from them. They will sell you only what you need.
Do the headers interfere with the figment of the OEM lower sub cowl accessory from Yamaha?
Matthew H on Sep 4, 2015
BEST ANSWER: Hey Matt, these shouldn't have any interferance issues with this kit, I plan on getting a sub cowel later on also. The headers didn't seem to change any from oem fitment.
Does this kit has a connection to the lambda (oxygen) sensor? im planning on buying one of these, but im not buying any fuel controller for the moment
A shopper on Dec 6, 2014
BEST ANSWER: Yes the header comes with the bung already welded in for the O2 sensor.
