New under tail exhaust

bikefriendzy · Oct 23, 2008

Hi All. Just stumbled across a new under tail exhaust that really looks cool. As in FANTASTIC !!! From what I heard, (short you tube video clip at Fastfreeks) it has a very nice sound, looks virtually crash proof, looks lightweight. I'm going to try & find out where to get one. Anybody seen it yet? Know where to buy? If you find out, please let everyone know. This is what I've been waiting for. Bikefriendzy

Nice find!

Would like to see pipe runs, and how the brake light went with the heat.

Those mufflers are TINY.

I'd like to see a close-up of the plumbing on this. Just how much room do you have left between the tire and the inner fender ?

Bikes that are produced with the exhaust under the tail are usually that way because the exhaust ports are facing opposite of ours, and so it makes sense to run it under the seat and tail.

I love the way it looks on the bike, but the tubing has to have many bends. As far as performance goes, the more bends in the system, the worse the flow...and less power.

Looks like any bump would cause the rear wheel to hit the mufflers!

i don't think thats so much a problem psike, but i definatley think that on a long trip, the brake light might start to melt.

rockstar4christ · Oct 24, 2008

Yeah, even on some of the zx6's! I have seen the paint and rear melt away! Great idea>!

Anybody know how that indonesian guy modded his?? From just remembering the pictures I dont belive his hedders came outside of the farings. Im way to lazy right now to go look for the pic...haha Just a thought.

nice! look pretty sweet! do u think heat wrapping the piping could save a bit of the paint and rubbers?

Felix · Oct 29, 2008

Pretty sure your right weth56... its somewhere in the 'best exhaust' thread.

it looks dope but yeah too many bends, id say if you do undertail its not for performance but for style and looks and thats cool too!

Hi All. I am selling this bike with or without the custom exhaust. It only has about 400 real easy miles on it. It also has just about everything & anything you could do to make it one of a kind 250R. It was to showcase a whole line of products that we were going to market, but the timing was all wrong for the economy. I live on the central coast of CA and will gladly show the bike to prospective buyers. We built the exhaust more for looks & exhaust not more than power. We never had it dynoed. I personally think that a bike that puts out so little power, to begin with, isn't worth the expense of dyno time. The project far exceeded out expectations & I have been stopped at every place I have ridden with numerous questions. Other notable mods are Dash 2 Braided SS front brake line, Dash 3 for the rear. Drilled rear rotor. Alloy side stand 1/2 the weight of the original. Safety wiring throughout. Dzus fasteners on part of the body work. Tall gearing for mileage & lots of TLC. I've never seen another 250 like this one. Please no low ballers. Thanks

I posted up pics of another under tail exhaust. Its made by sportisi motor...im waiting on word to see if I can just buy the mid and tail section if it will mate up to my sportisi header...

the exhaust is quite god but i think it is too close to the braking lights. so the pattern should be changed accordingly.
