350x
I want to get a little more power out of my 350X. I was planning on drilling out the stock muffler to get rid of the cone that's in there so it will breath a lot better, drill some holes in the air box and re-jet. Has anyone else drilled out the center of their stock muffler? If so, how did it work out for you? Do you think I'll get a noticeable power increase or should I not even waste my time?
