i would like to know what gives you the most power gain yoshi or e-series. i have a 300ex. i havent decided which one to pick up yet i thought you guys could help me out with this one. thanx:devil

Id get a E-series if it was me. You almost wouldnt believe the power gains. there almost as much as the best racing pipe.

And,its cheaper, and is alot easier on the neighbors...
