Where exactly does the Yoshi pipe give the most gain on a Raptor? What about the Sparks x-6?

 

Yoshi is a good all aroung pipe when jetted right

Sparks X-6 is the just better everywhere low mid to top

 

Anybody else? I need as many opinions as I can get. I have proof that the yoshi system is really good, but I never see any Sparks exhausts in magazines???

 

The big proof was at Four Stroke Wars the Curtis Sparks bikes killed ALL

 

Pat- Did you notice the exhaust that sparks was running on there quads??? I do not see any running around with the end cap like they were running??? Looks like they gutted the can and welded a 2 inch opening onto it.

 

the FSW's pipes had larger stamped perforated cores. cheese grater style instead of holes.

 

Sparks Hands Down !!

 

Yes Mark i asked Sparks about that and if i could get the same end cap they ran instead of the turn down that I have and they said the ones for FSWs were 1/4 bigger hole and straight out and made for those bikes ONLY and They told me the can and cores were the same
