Hey guys,

As alot of you know im building up my 70 as we speak. Right now it has a yx 150 and a ported v2 head. The stock pipe isnt cutting it anymmore. lol. So my question is whats the best pipe for this setup. im willing to do a little fabrication here liikke making a new mounting bracket or something. i reallly want either a carbon 4.1, an ultima, or a yoshi pipe. what do you think is the best for the setup?

Just talk to some of the SSR dealers on this site, and see how much $ they will sell the exhaust for. i'm pretty sure it would be a direct bolt on, and give you the flow your lookin for. (my 2 cents).

Is it still a 150? Don't you have a BBK kit in there?

What size is your engine and we can help you with your decision or you could just build one.

It's not that hard.
