I had the OE set of mufflers from my old XC so I decided to play with them. I got this from a guy with a Honda I met along time ago, I just drilled out the inner plug but also drilled 4 small holes onthe inner and outer side of each muffler and also through the inner center pipe, sound like a little louder than stage one with an almost HD potato type sound. No pops or back fire at all.
I just called it the submarine mod because it looked like a submarine with the little holes in them. I just installed one side to try it will install the other and will go on a spin if it stops raining. when I started one side I kept on drilling through the inner pipe so it went through the opposite side.
