Hi Hanso, need some advice please. I just purchased a 3 into 1 slip on pipe from Dain/Triple D Racing, I have K&N underseat filter but am thinking about airbox mods and tune. What do you suggest? My bike is 2014 Roadster and had stock exhaust until last weekend when pipe was installed. Bike seems to run fine but have not been able to test ride because I have a broken leg at the moment. Thanks!
