yosh doesn't make an underseat exhaust do they?? but i cant find shit on ebayThey all sound good. If cost is your main concern, pick up a used slip-on of whatever brand is the cheapest at the moment on eBay. Probably get a stainless Yosh or something like it for a couple hundo.
all in all, was about $200. got the pipes off craigs list, then ordered the baffles off ebay. i was going to get the yami baffles instead of the zx, but the yami ones sold before i could get them. the zx ones are almost identical to the yami ones, only thing is i they are held in diferantly, so if i could have gotten the yami ones it would have been less work on my part.that's a bad-ass pipe helo, how much did you pay for all the parts?
