Almost perfect. I've done the O2 sensor removal. fz10.org/thread/525/fz-10-ecu-sensor-removalDid the de-cat process and installed a Danmoto mid-pipe. (Including EXUP removal.) fz10.org/thread/560/de-cat-procedure-stepBlocked off the AIS using a cheap, non-intrusive method. fz10.org/thread/627/budget-non-intrusive-ais-disableSent the ECU to 2 Wheel DynoWorks for flash to remove factory restrictions and tune for the mods. fz10.org/thread/546/2wheeldynoworks-ecu-flash-review-threadThe bike runs extremely smooth. No flat or soft spots in the rev range. Not even a hint of popping or backfiring. Deceleration, even in B mode is smooth, even and less jerky than stock. Power comes faster and harder. Third gear throttle wheelies at 70 mph are effortless. The only complaint I have is that the bike is now too loud. The stock silencer has no DB killer and is just a straight through tube with perforations and baffling material. The sound is much like an open pipe raspiness, but not as loud as an open pipe. Still, not neighborhood friendly and definitely audible at speed to everyone within a few hundred yards. I'll likely get a different silencer. I hope a quieter silencer doesn't damage the current performance. |

Now with how you did the AIS block off, does your flash leave the system engaged still?

I agree great write up and information. The noise would be an issue for me too. I like to be stealthy. Let us know if you find a silencer you like.
Thanks,
Greg

I've tried Two Brothers and Hindle. Both are louder than I like but the Two Brothers with the db killer i can handle. A guy I know put a Remus on his FZ10 and it sounds great. I'll probably go with Remus but my wife is no dummy she knows I've bought two systems already.

I'll probably go with Remus but my wife is no dummy she knows I've bought two systems already. My wife is a finance director. I rarely get anything past her. That remus silencer wa the first to catch my eye when i first bought the bike. I may need to take a second look. |

I had the same mods and also felt the stock can was too loud. I swapped to a yosh alpha 3/4 system and it's much better. The note is nice and distinguishable, not just a blaring and screaming sound (nothing wrong with that if you don't have neighbors lol). Yoshi's have always been quiet in my past experiences and it was nice that this one came with a db killer.   uploadDoes this exhaust system have a removable core if you wanna make it louder? |

Do you have a dyno graph for this? I want to get this exhaust with an ECU flash but I can't seem to find anything about it. Like HP an torque? And did you completely remove the EXUP servo and install the servo buddy?

The baffle is removable, yes. Without the baffle it is almost as loud as stock muffler with decat but without the rasp.
I don't have a dyno graph yet, but it should put out similar numbers to a Danmoto decat/stock slip-on setup and ecu reflash. Apart from better fit and finish (mounting holes actually line up/doesn't rub swingarm), the midpipe is slightly larger diameter in some places than the Danmoto. It didn't change what map Nels decided to load in for me.
The exhaust is a yosh mid pipe and yosh slip-on sold together, so it deletes the exup all together. No error code because I had the exup and O2 sensors disabled when I had the ecu reflashed.

I have a question. Why does everyone take the O2 sensor out? It seems to me the ecu needs it to adjust fuel delivery for altitude if you go for a ride up in the mountains or down in a valley. Just wondering what the reason is.

This is the Yoshimura with the sound insert. It's not a baffle, it's a short tube that reduces the diameter slightly and forces the gas flow into the perforations for sound dampening. The muffler itself has a fixed (non-removable) baffle similar to the stock muffler, but with a larger, differently shaped chamber.
The sound insert tube is snugly inserted and fixed with a fastener. I'd have to take the muffler off to get it out. That's not in my current plan.

Did you completely remove the exup servo motor under the seat? I have been reading online that you can completely remove that unit and get a servo buddy to plug in. And you bought plugs for the 02 sensors correct? Just trying to figure out everything I need before I pull the trigger an buy the exhaust. Thanks |

You can simply remove the cables and leave the device under the seat. The valve in the exhaust goes away with the cat. You can alternatively buy the servo-buddy. If you have your ECU flashed, you can have the EXUP code deactivated. In that case, you can remove the servo motor without the need for a servo-buddy. Regardless. If you decat the exhaust with a 3/4 system like the Yoshi Alpha-T Race AND you have the ECU flashed, you will need plugs for the o2 sensor bungs. If you DON'T have the ECU flashed, you don't want to remove the o2 sensors. However, decatting the system and not changing the tuning (flashing) will make your bike run lean. The ECU flash corrects the fuel mixture (plus it disables throttle opening restrictions, and top speed restrictions. As I mentioned, it can also disable the EXUP. Check the tech section for the sensor removal thread and other threads for decatting, blocking off smog relief ports, and for ECU removal/install for the flash process. |

Slv has got it well covered. The reflash goes hand in hand with an exhaust like this. Made it convenient because I didn't have to buy a servo buddy. I removed the servo and cables all together, frees up a tiny bit of room under the seat. The servo is secured with a rubber o-ring so it was pretty easy, the cables were tough to get out so take your time or cut them if you don't plan on using them again in the future. Reflash also deactivated the ais system.
No need to buy O2 sensor plugs if you can source the bolts. I paid less than $5 and got mine at ace. Just had to cut them down to length because I couldn't find them short enough, no biggie.
For the plugs, you'll need (2) 12 x 1.25 x 20 Stainless bolts with (2) 12mm stainess lock-washers. Credit to operationfz. Like I said, cut to length if your hardware store doesn't have that short of a bolt.

Still not sure why everyone is removing the Oxygen sensors? They work with the ECU to adjust fueling from richer to leaner if you go up or down in altitude. I know they don't adjust a lot but what's the Benifits in removing them. Doesn't gain you more power. Doesn't save a lot of weight. Just curious if someone knows something I don't.
