i have a sparks big core and i was wondering what the best drag pipe would be for my yfz. i have heard a lot of good about the fci/mmad pipe. i just would like some info on all the pipes inframe(exug) or oof.
that RIS pipe looked really good to me.. the jsr pipe looks just like the nmotion rappy 700 drag pipes and they sounded really good. not sure if stallworth was building the duals for the rappy also. not all that sure who built the nmotion raptor drags??
There is no one best pipe. You need to buy them all and dyno them all back to back. Then you will have the one that works the best on your build. Expensive yes, but do you get the most out of your bike you dang right you will end up with what works best with your build. You can then sell all the other exhaust.
