I am thinking about going to the single 3" exhaust that Cotton's offers. He said it comes with a Dynomax race magnum muffler. Is this muffler the same as the Dynomax Ultra Flow oval muffler?

I have used the Ultra Flow on a single 3" system and it was quiter than a Flow Master. I am not sure how loud the Race Mag. is. I like the Ultra Flow because it is quite.
