No back pressure is a myth anyone who tells you otherwise has no understanding of engines and exhaust.the valve is there to control exhaust reversion every engine has a certain area where the engine is trying to suck air in from the exhaust and is quite noticeable and will give poor throttle response and feel flat this can be tuned out if you know what your doing.if you take the valve out and not bother to adjust afr ign ext of course it's gonna feel like it lost some but tuned you will gain.no back pressure is needed past the collector only velocity and length play a role.longer mufflers do not increase performance because of more back pressure it is only because of the length added to the system a muffler itself will actually give you less back pressure than a straight pipe

From how it looks I'd think you would reattach the cables to the exup the way it came off the stock unit and run it that way

that graves bit looks amazing but I find it hard to justify the money. Mid pipe blockoffs and flash seem by far the best mod

Just curious if anyone had a bike on a dyno with the new Graves EVR system and proper AFR setup? Would like to see the potential "smoothed out" power and torque curves throughout the rev range. More interested in the complete curves than max numbers.

Dyno numbers and curves can be funny sometimes don't put stock in it.i think the one way to really tell is to have two r1's one with valve one without identical weight rider and do a roll on from 5k up

Take the stock exup cables and attach them to the Graves exhaust > Use an activation code inside FTEcu's software to unlock the EXup parameters to Graves' setup

Yes, correct

woolich uses the Exup plug for their hookup for the blipper and qs.

I wouldn't use the woolich stuff you get what you pay for. There's enough FT deals and packages with exhausts that you can find a good price

They aren't on the site yet. I have R1 with 200mm Ti silencers (what our superbike team runs) instock. MSRP is $1749.99 (Part # EXY-17R1-CVTT). One of the hold ups is the FT map card activation codes. Anyone that wanted the pipes early we contacted everyone that used the website to question. We did allow pre-release orders and some custom silencer type builds. If you weren't wanting to purchase at that time no big deal. We don't release parts just to appease customers. Our R&D work both product and electronics is extensive on and off the track


Teaser Video of the titanium R1 cat eliminator exhaust with 200 mm Carbon slash cut silencer. These systems will be available in set lengths and custom build sizes (200mm , 265mm and 300mm). The exhaust valve race uses the factory exup cables alongside the Graves EVR valve to fine tune low end and mid race power along with throttle response to create and better powerband and ride. This is particularly effective on exhaust systems with shorter silencers that can rob your bike of power and be extremely loud.

Shane, I just installed your 3/4 graves pipe on my 17R1 with the unrestricted FTECU flash.When will the Grave flash be available for the 17.

Just use the file from the 2015 R1 that's in the list, it's the same thing unless you have an R1S. Nothing is changed unless you want to get your bike dyno tuned or run the FTECU Activetune.

sorry to burst your bubble but the woolich auto tune is quite a bit better than FTECU. many many more settings. one of the most important of those is the ability to change the header length and diameter for exhaust gas offset. which gives it a more accurate reading. along with many more settings for the qs/blipper than ftecu. I could even take the wideband setup off and use it on my car if I want. I'm not stuck with a useless unit that only works on my bike. http://www.zeitronix.com/

and they don't need 2 qs sensors because they're not retarded and know how to make a 2 way sensor.
don't get all super proud of that exup. just months ago you would have told everyone exup sucks get rid of it.

You don't need to be nasty to support the product you like, however you should consider what your going to say before you say it.

You didn't even bother to articulate what the 2 systems do differently.

Everyone knows the FTECU system is more effective for the everyday user.

As for the Graves EVR - hands down the best pipe on the market in terms of build quality and performance. Graves is way ahead of the curve in this!😊

go on youtube and ask marcel irnie his opinion of his graves full exhaust header blowing apart in a race. Skip to 9:15

both FTECU and woolich are about the same. neither one of them is any better than the other. one does some things better and the other does some other things better. woolich went with an odd way of using the exup plug for the blipper and QS. so yeah if you really want/need the graves new exup setup I guess you can't use it with the woolich stuff. who cares if ftecu has a bigger following and more pre made maps available. that stuff is actually useless if you really want your bike to be correct you can't rely on that crap.
you need to have one done for your bike on the dyno.
the graves and ftecu guys on the forum act like the products they sell are the only viable worthwhile options out. and that's not the case. in fact I bet most of the racing world has never used a graves or ftecu product (wsbk, bsb motogp etc). ftecu is a decent product of course. but it's still not all that the vendors make it out to be. if it was it would work without wifi. have fun at a track you absolutely need to make a change to the bike and you cant because ftecu in their infinite wisdom decided you can't use the software unless you're online. and lets not forget the sneaky update they did to the old system and bricked the older devices on guys and told them tough shit. now hows that for "getting what you paid for"? lets here spiderman ss explain that one...

while you're out of luck packing up for the day I'll be over here using my woolich to tune on mine offline. you know, because I bought it, i get to use it wherever whenever I want...
