added Graves exhuast and HORD intake

Recommended Posts

vcyclenut

ive been a long time user of Graves.  On a motor with this configuration(inline twin) there is not going to be much difference in performance between systems but my goals with this bike include making it as light as possible so the titanium system fits this goal. 

I am also a huge fan of Graves quality and feel good about supporting a true American made system 

The easiest full system I have ever installed on a bike and the sounds is pure eargasmic!  one of the best sounding bikes ive ever owned.

very nice! sound clip?

you planning to use a fuel controller or is the stock ecu able to compensate?

That is an expensive piece!  I have heard them on ninjas and they sound awesome.

+1 on the sound clip! I've really only seen a few clips on youtube with the Graves setup but soooooo many more of the Akra pipe and the price is pretty comparable.

I have the Graves Exhaust on my FJ-09( Tracer900) and can vouch for quality and workmanship... But Graves is one of the very very few I have seen that taper/step the header pipes, midpipe vs just sliding two pipe together via a thick weld in the aftermarket world vs a hand built fancy factory rider was only exhaust piece... with Graves you get far more(workmanship, the R&D, quality, technical technology,etc) for the price vs paying a premium for the "Akra" name in my opinion...

2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW

I have a 2019 MT07 and have had the Graves complete exhaust in my "cart" since the second week of March.

+ 2 for the sound clip! I'm ready to pull the trigger on it... BUT...I know you need to tune/flash the ECU after changing the exhaust.

I think that one of the on bike flash kits or bench flash kits would be the way to go seeing as how all O2 sensors interact with the ECU in real time to make adjustments these days(Ruling out the self learning or self adjusting O2 sets).

 

I have a few questions for you on what you used post installation and would love any + all feedback from other people who have done research on this.

What brand/style did you use, how do you like it, what would you go with if you could do it again?

 

Thanks!

I used an ecu flash,  the o2 sensor does not give feedback like you think.  It is purely an emissions device and is only active at light throttle and lower rpm.  for best results it should be disabled.   The stock o2 sensor is narrow band and is not capable of doing what you think it is doing.  Do  not compare modern automobiles to motorcycles.  Modern cars have wideband o2 sensors and work like you are thinking the bike does.

 

the flash tune software does not support o2 disable but the woolich software does

I was really torn between the Graves and the Akra Ti when I bought mine. In the end I went with the Akra purely due to the underbody position of the muffler as I feel it makes the bike look cleaner.

Vcyclenut - You're spot on with the confusion. With a background in automotive, I assumed the bike O2 sensors operated the same way.

208MT07 - I was considering the Akra because of the clean look but ultimately liked the sound better from the Graves clips I have seen.  I was on the fence as well.

 

Thanks for the feedback and I'll post a clip of the exhaust once it's all done!

I don't have any sound clips available right now as I'm on business travel, but since this post was made I have purchased and i nstalled the Graves exhaust on my 2019 MT.  Along with the install I removed the snorkel and did the 2WDW ECU flash. Concerning the exhaust alone - I'm an engineer and over analyze every big decision...i looked at the 3 main companies in extreme detail. I cannot explain how happy i am with the purchase of the Graves unit. The quality, weight, design, fit/finish - but above all else the sound. I have the baffle out and its not much louderr than stock. I dont do track days (yet), and don't find it to be annoying at all.  I've head several friends and family with motorcycles check out/ride the MT and are shocked at how good/better it sounds. I cant recommend the Graves system enough!

As an aside, after those 3 upgrades, it's a completely different bike. The sound, the smooth and increased power delivery - totally worth the investment. It's shocking really the difference to stock.

Thanks a bunch, that’s what I was hoping for as far as a response. I pulled the trigger today on the Graves and will sell the M4. I also have snorkel delete and 2WDW flash and they recommend me sending my ECU back for a re flash so that’s what I will be doing. I also did a lot of research and your findings just confirmed what I have found

Real happy to hear about the sound. Just what I am looking for. Thanks for the review!

@watarski Thanks much for the post. I’ve done the snorkel delete on mine (it’s a ‘15 I got used a few months back) and decided to wait on the @2wheeldynoworks until they have their Black Friday sale this year (hopefully they will!!) and have been trying to decide on an exhaust. I have yet to see any other FZ-07’s here in the Charlotte NC area let alone one with an exhaust, so all of my research has been here and YouTube. With the “big three” I’m assuming that you are talking about Akrapovic and Yoshimura, but who is the 3rd ? Any more details on why Graves over the others - especially considering the price of the Graves system (I know you get quality with all 3 of the above manufacturers). 

Lastly, where did you end up getting the Graves system from?

thanks!

Please let me know your impressions vs the M4 when you'll have the Graves exhaust and the (re)flash done!

I currently have the 2WDW flash for/and the M4exhaust (since last 2 years), and snorkel out (but only since +-2weeks ago, and it is indeed worth it!), so basically the exact same setup as you AND also looking into swapping my M4 for quite a while (don't get me wrong, I like the M4 sound without the baffle, but without it, it is fu***** loud, even with earplugs!  And with stock db killer, still too loud for me, but with Q2 db killer, decibel-wise it is fine, but looses a bit of those deeper tones, and gains a bit of "braaaapy"ness sound, which I am not a fan of...)

At the moment, leaning towards Akra Ti (as it seems to fit my bill), but curious to hear from you before I pull the trigger!

Those gains are impressive! An extra 10hp peak and a crapload in the midrange.

I'm running the Akra Carbon baffle in with no tune, everything else stock. I love the way the bikes performs as is and have no issues with it at all. But if I can get your gains (or similar) with a HORD intake and a custom tune I might actually consider it.

Hords intake really let's the motor breathe in air vs the OEM airbox ( granted it was made to meet various regs/rules- but it works for what's it's made for)... This intake style should have been used from day one in my opinion... Hords intake with aftermarket exhaust will yield very similar results as the exhaust themselves are fairly (+/- 2hp/TQ approx) close in Dyno graph overlays/numbers...

I will have exhaust on tomorrow and ECU back Thursday and will shake it down and report my “butt dyno” results as well as sound. 

I liked the M4 okay too but wanted a Ti system and I have not heard a bad review or seen bad dyno results. I am also running a big mouth intake but this Hord has me 🤔

Got all back together and took for a quick spin at lunch and I really like the Graves a lot more than the M4. I installed the Graves without the baffle and the note is awesome! Not as loud as M4 (I like) but is not quiet by any means. Hard to describe but sounds more “tuned” if that makes any sense. I didn’t wear my earplugs and was not bad at all.  I know the Akra is a favorite but I am more than happy I went with the Graves. 
Butt dyno can’t tell a big difference and still pulls real hard in the midrange (love this bike 😁) and no popping on deceleration thanks to 2WDW!  I couldn’t go balls to the wall due to where I am at but will get out of town this weekend and will be able to pound on it more. 
Overall I am super stoked and pleased!

@1tondriver

Thanks very much for your mini review!  Good thing to know that it seems (much) quieter than the M4 to the point that you don't even need earplugs, even wihout baffle! 👍

The only downside from the Graves exhaust that I saw (on my end) is that it is even more expensive (1400$ CDN + taxes, which are 15% here in Canada, so would come up to 1600$ !!...😱) than the Akra Ti (1200$ CDN + taxes), which I tought was THE most expensive of all FZ07 exhaust...

But at least, now I have a good idea of the Graves vs the M4 thanks to you!

@kylerhsm

Do it!!  This ^ + the R6 tube (I know you're considering it as well ;) !) and for sure you will feel you'll have a whole new bike (for the better), a kinda FZ07 - v2.0, and you will NOT regret any of it!

Minimally, I would at least strongly suggest you to do the 2WDW flash since you already changed your exhaust because the bike (stock exhaust + ECU) is already a bit on the lean side, so with your exhaust it's already leaner, which you dont want (not good at all for the engine) and as is, your bike in it's current state most probably lost a bit of torque with your stock ECU + your exhaust (lots of posts on this).

I know you love the bike as is and have no issues with it (exactly like I did before the few mods I did), but it really does get that much better with all those tweaks,  the only thing you'll regret is waiting that long before unveiling her true identity and full potential!

Stop considering and start buying! ;)

welp, I have somewhat a different setup...

Yoshimurs full exhaust

DNA filter, modified the Top myself...

ECU  Flash by 2WDW

and it's really very nice....lot more power, and it makes the same power with, OR without

the  Insert...(according to 2WDW).....I run with the insert in, sounds great but not tooo loud...

I also switched to 520 chain, (RK GB520GXW), and a 17 front and 42 rear, (both Supersprox steel)

they re-geared it from 2.6875 final to 2.470...not a huge difference, but nicer on the straighter roads

did the rc throttle, love it..

Have a Ktech RCU Razor-R Lite shock coming, and a Corbin Gunfighter.....

that oughta do it....cept for the front boingers....

You are in a conundrum with the price difference for sure. I don’t think you can go wrong in either direction. That CA tax is brutal. I am very impressed with the craftsmanship on the Graves, it is impressive. The can also goes a little more rearward than the M4 (it’s longer) and I think that helps with the noise to the rider also. Going to take some pics tomorrow for the insurance company and will post a few up. Good luck with your decision EZrider, it’s not an easy one.

A couple of pics of the new system. If there is a better sounding one I would like to hear it. I am considering the Hord but can’t find any good info on installing. Any help with that is appreciated.
