Forget buy what you like. If your not happy with it trade it off for something better..[img]i/expressions/face-icon-small-smile.gif[/img]

 

PatsRaptor I will be more than happy to post my gains or loses on the form. I hope after FSW when CrayCraft gets back we can schedule a weekend to do this.

 

Great Ernie I don't know anybody here that runs that pipe and hope to see some run on a stock raptor to see there performance at FSWs

 

What are your guys impressions of the Yoshimura full Raptor pipe? Pros and Cons?

 

I really like it - but my perspective was one of "overall quality and performance" rather than absolute power gain. I replaced an FMF powercore 4 (that fell apart) with the yosh full. The quality of workmanship, design, and performance is a very nice match. It's VERY nicely built and I think it will be on the bike for quite a while. I cant comment on the quality of the other pipes mentioned (I'm sure they are nicely built) but if they are not built well and fall apart in a season then I dont think it's worth the couple extra ponies - dollar for dollar. It all depends on your final goal.

 

I wish Graydon would do something about the headpipe design, to make thme look better.

 

Actually, the Yoshimura full pipe puts out one of the highest HP gains. So your not just getting quality without top performance. I know you get more HP with the Yoshi than with FMF and WB.

 

Yep - my "seat of the pants" dyno noticed a nice increase !

 

I liked my Yoshi when I had it and had great luck over the W/B I had. Good over all pipe system
