Hello all! I have a 2007 Sprint on order and me being new to the Triumph scene, I would like to know about changing the exhaust. I know Triumph makes a different silencer. I think that is what they call it. Does it remove the Cat's? Also do you have to calibrate the ECU with new exhaust? As you can tell I am a lay person and need to learn from all of you on this forum. Thanks in advance.
