Which of these two pipes are going to give me a better performance?

 

on what kind of quad

 

Yoshi.

 

2004 Yamaha Raptor. What jetting options do I need to look at it? Will it help to buy one of those K&N power kits, that comes with the outerwear, filter, and jets?

 

I've owned both the the Raptor and I'd have to say the Yoshi makes more power and is built with better quality. Don't get my wrong, the e series is a great pipe but not for high HP. Very strong mid and low though! Also alot louder than the yoshi.

 

i got the comp full kit yosh for mine and the screws that hold the endcap on were all striped out. The dealer said that yosh would warrenty it but i didnt want to talk it back off and send it in so i taped it and put in larger. I love the pipe but think the quality could have been better.

 

Yosh, WB is crap and it sticks out way too far.

 

yosh by far

 

Where did you get your Yoshi kit from. I just bought a Raptor last week. Today was the first time I rode it and loved it. Just want to kick up the horse power a little bit.

 

Yoshimura and White Brothers shouldn't even be mentioned in the same sentence.


Yoshi is superior in every way, and then some.
