Dual Exhaust on my 700xx

So if you're paying attention, I have my quad apart right now... Entire exhaust is off as well. I'm looking around and i'm PRETTY SURE I could put duals on it, with a little bit of custom pipe. It would have to come from a single pipe, then "Y" off to duals but...

My original unorthodox way was with a single 07 GSXR pipe as seen below.




Now i'm thinking I can come up under the airbox, through the chain and up over the frame rail to the other side. I think my questions are... what do you think of 2 mufflers this same size will do for performance? Sound? Efficiency? I know one thing... that single short muffler was pretty freaking loud. You could hear me from a LONG way off, i'm not opposed to using longer mufflers, other manufacturers, even stock mufflers off a sport bike, but i'm pretty sure this could be done fairly easy. What do you guys think?

I am trying to do something similar. If you know someone with a Twin pipe CRF250r, that's what I basing the idea on. 2-1-2 , my way of having a full power and 94dbs. That's the plan.

How would it be 2-1-2 when it starts off with a single exit exhaust? Wouldn't it just be 1-2?

I bet you noticed the crf have a smaller exit on one silencer: the left side is longer than the right side so this is for balancing flow.

I did notice this but if I can make it work with the "RR"( XR head) then I'll make it fit the "XX"
It involves a new airbox and some stuff.

Oh yeah i'm in the thinking of this because of the same reason, noise restriction here we get 150$ ticket...I thought of battery relocation and shorten the intake tube. By the way ltr450 people use crf throtle 50mm http://www.kmsperformance.com/shop/item.aspx?itemid=4, so I just can believe no one here tried it:/

I don't believe you. Pics or it doesn't exist.

edit: since this is my thread, i'll allow a LITTLE off topic.
