Two of my friends have YFZ's. One is stock and the other has the GYR-T slip on. The one with the stock YFZ want to get a pipe, but wants the one that will give him the best hp gain. He said that he read about one called a "protech mach one" (that might be spelled wrong). He said it's supposed to give it like 11hp's vs 6hp's from the GYR-T. Can you guys help?

 

You're going to get a different answer for every pipe on the market. I have the GYTR and very happy with it. Didn't get beat by any YFZ's at dumont a month ago up the hill.

I think overall they are all close. Doubt you will see any major difference like 5hp though. Seems a little off.

 

I would get whatever is cheaper

 

From what I have heard, The GYT-R pipe and the Sparks pipe are leading strong.

 

anyknowlege as to where to order sparks?

 

www.sparksracing.com

 

dduurr lol
i wanted to find other places to buy from..shop around

 

I believe you can only get the sparks from sparks only...you have to call.

 

you can actually ask for one of their distributors closer to you than their main office........
that is what I did .............and I got a better price..........
481 for the stainless pipe and jets/needles to my door
retail is 519 plus jets and shipping........
