    MNNTHBX Underbody Exhaust

    Now shipping via http://www.mnnthbx.com/product/dual-underbody-exhaust/

    About the MNNTHBX system... The design goals were to provide the best "race" level performance exhaust we could, and in that, I'm confident with what we've achieved. Testing against the Yosh tells me this is a VERY good performing system. That said, in the near future, I'll gather some solid dyno data to back that statement up. It has twin cores, although they are small. In terms of volume, be aware it is louder than most, but holds a great tone, and is nowhere near the insane volume levels of my Ruckus systems. The impact on handling is huge. Not only are you dropping lots of weight off the bike, but you're taking the remainder from high on the bike, to the lowest possible point. Ground clearance remains fantastic, and the overall lines of the bike are substantially streamlined. For those wanting to self tune, I have stainless bungs specifically for this pipe on site.

    I think I have decided I want to go with a low mounted exhaust. I would be interested in this one but (and I kind of hate to admit this) I REALLY want to keep the noise down. Stock is 80 DB and the Moriwaki is 86 DB. So.... if you can make it tunable for noise/performance much like the old Supertraps that would be a HUGE plus in my book.

    If its anything like the other pipes he makes.... They aren't..... Quiet really... Lol. Stupid nice and well built, but not quiet. But on this bike, I like that idea. On the ruckus... It was kinda funny because this thing was making soooo much noise and not really doing anything. Lol.

    From testing, the tone (of a single can) has a far less twangy sound than the Ruck. The duels expose it to twice the baffling, and it's pointed at the ground instead of the side of your head like the Ruckus, so they should be worlds apart in terms of sound.

    Have you guys considered a semi-helical header for that setup? Just a little more distance from piston to tip? Could help with mid range torque....
