DIY Installing your slip on (Leo Vince used for this example)

[Micah / AF1 Racing]

More Tuono V4 porno pics...

so this is what happens if you decide passengers suck...and decide to install the structural carbon bracket that is included with the Leo Vince slip on exhaust...so ugly...hideous...cannot look away...fuck I love this bike...must save money...airplanes....look away...




Now back away a bit, it may look worse from a distance right...



Better check the other side...oh hell, it looks even better! I am not single, why do I need passenger pegs again...

Did an Akro Carbon slip on on a Tuono V4 this week too, very friggin' nice pipe and shaped the way I like...and of course there is the sound issue, it is perfect baffle in or out, not too loud with db killer removed.

Here is the bike:




This is a closer look at the pipe. A Lot of people seem to think the Akro pipes look too "old" now, they just look "right" to me...which probably means I am getting old....




Now from the rear, my preferred position, oh wait, that sound bad...




Opposite side of whole bike...this one had mirrors removed and replaced with Rhino Moto bar end sliders and fancy CNC alloy bar end mirror on throttle side. I was a bit surprised I could actually see pretyy well behind me with this little bit of kit installed.



I am unabashedly pro Akro. My reason vary from perfect fit and finish to little details like this spring hanger. This is like the most precision non aviation band clamp I have ever seen, that is the Akro one forward of the centerline of the EXUP valve in this pic. Little details like this go a long way with me!



Since this thread is about pipes I will keep the bar end mirror talk and bar slider stuff to a minimum, out of focus should do it right?

What's with the bolts and wires sticking out of the license plate? Is this something you do with temporary dealer plates or something?

[falkdal]

How does the sound compare between the Leo Vince and the Akro? The Leo is stubbier so does that make it louder? The Akro looks a lot longer in comparison.

[Micah / AF1 Racing]

The Akro is quieter than the Leo with the DB killer out. With DB killers in place I would say both pipes sound about the same. If running open though on boh pipes the Amro sound is a bit deeper, more muffled bass than the screaming cresensdo of the Leo. Shorter pipes typically sound a little "sharper" and this is no exception. Both made lovely noise.

Man those pipes are UGLY, prefer my Austin Racing can and doesn't need support off the rear pegs

I had an RSV4r in recently for a "make run" project with the AR can like yours. Too loud for my old ass. Also worthy of note, that bike required race mapping just to get it close to ok with AR can. It was definitely small and MotoGP looking but I think I have heard quieter MotoGP bikes. I buy suppressors for my guns though, I am just plain noise averse.

That said I installed a generic set of DanMoto cans on an Akro race system yesterday to replace damaged Akro cans. Those things are a bitch to install, apparently 60mm in Chinese translates loosely to 59.45-59.95mm in English.

Actually I find the AR can fine with the baffle in, I have also had the scorpion GP-1 can. BTW, I hope everyone realizes I wasnt being serious about the ugly cans.........

Having test ridden a US bike with the stock pipe I didn't find the low rpm fueling to be bad in the city. It was a lot better than my old MV Brutale 910 for sure and seemed about the same as my V2 Tuono with 2-into-2 Akro race pipes. So from an initial impression it didn't seem like it needed the race ecu/slip-on combo to make it usable. Micah you've spoken very passionately about this mod though, is it really a big enough difference that it's worth doing even if the stock setup seems fine?

Also, as I am trying not to wake up my twin toddlers if I come or go late at night (currently I have to roll my V2 down the block before I can start it up), will either of those slip-ons with db killer in be significantly louder than the stock pipe or is it more that they sound better and fuller, not necessarily louder? Because the stock can was still pretty loud when I rode it yesterday!

[Micah / AF1 Racing]

I knew it was a joke about the ugly mufflers...no worries.

Yes and no on whether or not it works for YOU. I do not personally like the look of the stock muffler and the Akro looks right to me...so on mine it would probably be the Akro. Most people seem to like the "newer" looking stuff like the LV or AR and there is no fault with this. Buy they one you like the looks and sound of. I buy Akro because they have an entire building with nothing but R&D dynos running around the clock, they make their own tubing, hell the list goes on an on for me, Akro is first an R&D company and second a pipe builder the way I see it, and that is the way I like it!

The weight of the stock pipe is not too heavy, the sound is pretty damn good but, you will see a power increase through the middle and up top with most aftermarket systems and in some cases the fueling is much better than with the stock pipe and required feedback loop to keep a catalytic converter alive!

[falkdal]

Yeah I'm starting to lean towards the Akro actually. Weight and power aren't so important, but if the fueling is improved then that's worth doing.

Micah,

I know this is a pipe discussion but I like that bar end mirror. Any reason that would not fit my '09 Tuono? Is that Aprilia or aftermarket?

Pablo

[Micah / AF1 Racing]

It is standard Rhino Moto bar ends (for use with bar end mirrors) for pretty much all Aprilia twins. Same part used on earlier bikes, no worries there. I think those were Rizoma mirrors but might have been a CRG product, looked way to sculpted to me to be CRG however. I should have taken a pic of the box they were in!

[scott2ride]

I just received the very cheap, chinese made 'Danmoto' GP exhaust. Installed it yesterday but havent been able to ride the bike as I have no forks on it as they are getting a revalve.

Looks pretty well made actually.

Link pipe is a little sub standard but not easy to notice as it sits so low.

The bracket is totally shit and I wont use it, But am adapting a better solution

But the actual pipe s nicely made with superb tig welds.

Sounds ok at idle but probably quite loud when riding.

Looks great...

Will take some photos.

[Micah / AF1 Racing]

Yeah, when you first see the DanMoto "straps" you will about die. BTW, the rubber used is FAR from heat tolerant, turned a set into molten glue in 5 minutes on the dyno...but this is indeed a case of getting what you pay for. Scott, please add pics when you get it all finished up to fill in this thread with pipe options.
