running straight pipes

[Evilution]

i am putting together an exhaust system for my xb9r. it is copied after the xb race kit. no it says on there site it is for offroad strictly, why is this. i mean after all its a hopped up sportster motor and i have owned many cammed out high compression stroked 883's with striaght drag pipes. is it just because of the noise? the only reason i ask is this is m first sports bike.

thanks guys,
Marty

 

[twoguns]

its just because of noise and EPA regulations.

 

[Evilution]

oh ok thanks man. thats what i expected.

I have a straight pipe on my xb12. LOVE it!

 

[Evilution]

what ecm do i need to run with straight pipes? or will it work with the stocker? If anyone could through my a part number that would be cool. All advice appreciated.

what ecm do i need to run with straight pipes?

stock with a custom mapp

 

[Evilution]

do you have a recommendation on who can do the mapp? I email EBR and they said they do not make an ECM for straight pipes, they said their race ecm may work but would not be optimal. i miss the days of just running drag pipes re jetting the carb and you were done ....

If someone would design a drag pipe for the 1125s, I'd jump on that quick! With the help of theoctocpus, the bike wouldn't run near as lean and the worry about burning valves would be lessened drastically!

There is a Drag pipe for the 1125s sold by EBR Its just pretty pricey.

Yeah, I've seen that kit for sure, but I refuse to pay that kind of money for a pipe with a few bends and curves in it lol.

All a guy would have to do is be slightly creative on how to design a midpipe that runs along the bottom of the bike. Dean Adams has already come up with a great design utilizing a muffler. His Keda RT-2 has a dual outlet. Someone needs to do a drag pipe just like that and then tune it with theoctopus. I'd love to run straights and I would, but I don't want to possibly burn my valves and hurt my engine. I would run them with a proper tune though!

You could always run a carb, like the guys do when they build there mutants. You would probaly have to take a section out of the frame to make it fit.

Thanks vtech

Quick question about the straight pipes. I have a xb9r. What's the affect of getting rid of the o2 sensor? Any motor issues? Like many I'm used to older harleys and this is my first bike that came with a computer cable.

a friend of mine ran no muffler on his buell because he liked the sound lasted one summer,start of this year it jetisoned rear piston, tried to warn him
