2010 headpipe on a 2009 EG?
I bought two 18mm bungs and took 'em with the fullsac x-pipe to the welder ($25 for labor). I plugged the 12mm holes and installed the headpipe on the bike.
I couldn't believe the difference in sound with the fullsac x-pipe and the 4" Rineharts. I mean, I had the OEM catless pipes and they sounded ok, but know the sound is more deep and throaty. I can wait to take the bike for a ride (still cold up here in New England). I was told I should expect a light gain of 2-3 hp with the x-pipe. I'll wait till it gets in the 40's to go for a test run.
