In the performance motorcycle world for Dual sport and sport bike's the term for taking off the emissions crap for increased power and better overal performance is uncorking. People do it to the diesel truck's too but I don't think they use the same term. Anyway, I was curious if anyone takes that garbage off of their equipment. Blower's, Trimmer's, Mower's? ..and if it has a significant effect on the power. I know it makes a huge difference with motorcycles and trucks.
