must you really ask?
Barker makes a GREAT pipe for the YFZ
I have used Yosh, Doma, and GYTR
none come close in quality
the packing, the welds, the workmanship, and the customer support..
Really, Barker has them all beat
Intakes .. it boils down to the FCI and the Ron Woods
both good, the FCI makes slightly better numbers on the dyno
but you pay a bit more for it
Barker also has a GREAT ported head for that machine too!
