Has anyone ever seen underbike exhaust on an RC51?

I'm curious if anyone out there makes a good underbike system. The weight savings would probably be substatial, and the weight would be lower which would help handling.

I'm thinking of something like this.

I've seen people do it, but it's always crappy custom fabbed stuff with absolutely no sound muffling devices, so it sounds like ass. It'd be neat to have one pipe coming out each side, as long as there was no real compromise in sound.

There's so little space behind the sump , below the linkage, in front of the rear tyre and inside the fairing (panels ) , that it is even hard to connect both headers .
Why people ask questions like this without having a closer look before .
so you would charge an arm and a leg for an exhaust like that? totally understandable, but that is truly art. amazing work sir:rockon

Briliant Thorsten, The work you do is Second to NONE,.. IMHO Second to friggin> NONE I say!

The "Under engine exhaust" you've pictured here, is the Most Awesome, Coolest under engine exhaust, I've ever seen!.. ALL others and I mean ALL Others look like Cow Shit, in compairison! FYI and FWIW... I do NOT like any "shorty\MOTO-GP exhaust" and or any "Under engine canisters", of any kind... Well, that is until You posted your pictures here!

Thorsten: Acouple questions Please... as it seems to me,.. Those big ass, long as Shit Headers,..... WILL make a Whole hellva alot of Heat behind the fairings brother! So,..


#1) Why NO "Exhaust Wrap" on those Beautiful Headers?

#2) Your "mono Tail section\sub-frame" Super Sweet Job too by the way, (Looks like "Bimota SB6" design here, has really peaked your interests to creat Killer tail sections... IS this infact where you first saw "Tail sections" of this Caliber and Quality or? This is the question inside a Question LOL)... So,.. this tail section\sub-frame, she looks like a older(maybe) 05 CBR1000RR tail section... Yes\No?

#3) Do I see, you're actually using RC51 Coils on here?!? LMAO...


#4) For acouple years now, over 3 anyhow... I have noticed on your Web-Site.. When you make your own castings Engine covers and Oil pans and whatever else you want to make:notworthy You in your castings have "HRC" in a mirror imagine come out in said engine covers.. Years ago, I thought that maybe you just screwed up;) LOL... but over the years You keep making them in a mirror imagine.... Why?

Peace Jeff



PS. First picture, there's a little:rolleyes: green tractor behing the MC... Just wondering... Are you doing any Performance mods. on her?! Making her lighter, Boosting engine Bore and Stroke maybe,.. any "Carbon Fiber Small Batt. relocation mod." in the works? :woot:

Yeah, probably a 1098 considering the upper trellis tube looks a bit thicker, the valve cover is bronze and not silver, and the fact that T has been working on those one piece subframes for a while. It looks like he fabbed up a 1krr shape into the rear of the self supporting tail/subframe.




What's odd is it appears to have HRC scribed backwards on the left side of the motor.

You could always do something like the RC8
