I normally leave a bike stock and just ride it but is it smart to replace the cat with a Y pipe. I know the weight savings would be a plus but someone mentioned removing a large amount of heat from underneath the engine, that sounds big to me. Good idea or not? Will it change the way it runs to the point that I need to buy more stuff to fix what I have screwed up? Where will I find one and how much will I expect to pay? Let me guess there is a thread I need to read.
