I picked up 3-5 throughout on top of the K&N's which added 6-10 here and there.

Intitially i thought it wasn't worth it, but careful reanalysis of my dynos changed my mind. Biggest gain was to peak torque right around 5K.

Someone claimed a gain of 12 for the tubes alone (not sure if on a dynojet), but I've noticed that the first breather mod always seems to make the most dramatic gain, and all subsequent gains are less for the same mod if it is bolted on 2nd or 3rd rather than 1st -- probably diminsihing returns as you approach optimal VE for the motor. VVEL tuning should open that up further...

Anyway, if you are on a budget, just do K&N filters and don't worry about the tubes.
