98 just went back to blue from black/yellow, pro-circuit exhaust, AC everything, Vito work, pro-flo, douglas/kenda/holeshot, coolers, pro-taper, lotsa billet
90 red, fmf exhaust, k&n, dg stuff, Mc Creary rears
How can they be restrictive? Supposed to flow more. I don't buy the 7hp gain claim. My motor is .20 to .30 over with pro c exhaust and pro-flo intake, Vito needles.
I don't like bolting stuff on just so I can say I have something. Have an opportunity to buy some new ones cheap. Curious if anyone has the skinny on expected results.
