i have a question pertaining to emission standerds and my bike. i have the t-tuner midpipe with an m4 exhaust and was wondering if anyone else has the t-tuner midpipe installed and have had any problems passing emissions. i ask because i'm going to be moving down there from washington where there are no emissions standards for my vehicles. and want to know if i need to reinstall my cat. any help would be appreciative. thanks in advance.
