Mehh, shorties, 40's and o/r x sounds too tinny and has too much of a metallic sound. I ran that for a while with and without turndowns, I also ran 50's for a while. I thought the 50's sounded way better than the 40's. Without a cam, the 40's with an o/r x sound bad. I switched to MAC, and am MUCH happier. Don't ever want to switch mufflers again.
