I have the chrome rush pipes, with the extension and 2.0 baffles. They sound great, no drone. Had the 2.5's originally and opted for the smaller diameter after talking with Rush. Many compliments on look and sound. May consider 2.25 if and when budget allows. Rode in a class yesterday with Gls 1800s to 1000s and received nothing but compliments from the other riders. Many commented on maneuverability. "Ya just gotta luv it"
