i heard that on a newly rebuilt engine you have to break it in with a stock exhaust is this true?Also if i buy an exhaust i think i'm just gonna buy a used one does it have to be built for my bike or can i just get anything that the head pipe will fit into and make brackets to mount it,also i know it should be an exhaust from a 4stroke and from the same CC's range,so does this sound alright??

 

you can break it in with any exhaust you want............And your theory on the slip-on pipe is dead on...you may need to make brackets but no biggy.

 

good stuff thats what i wanted to know,sothe exhaust from a yamaha beartracker(230cc's) would be a good match for my ytm225dr..

 

In my opinion.......Yes!

 

thanks
