spike Posted February 19, 2009 Report Share Posted February 19, 2009 I could buy a set of GRR outframes localy. I'd use em for the odd drag race or burnout contest during local exhibitions. what kind of difference would they make from my inframes shearer's? (mods in sig). motor was ported for shearers.

Not much if any, stick with the inframes.. If it was a full blown drag bike with a big motor yes I would go with oof's for performance and plus you don't have to listen to them very long..

shanYE west Posted February 19, 2009 Report Share Posted February 19, 2009 oof pipes are usually good for about 2-3hp, Also.. sound wise i didn't see any difference from the inframes to the oof pipes.. Sounds louder on the bike since the pipes are right there rather then behind you.. but.. they still read the same on the tester. Quote Link to comment Share on other sites More sharing options...
