ok, cool, i have a "new" scat cat 500 with a 40 la (its going to be my beater plain as i learn more advance aerobatics) that i'm going to try this on. I know this pipe will be loud (don't care my field dose not have sound restrictions b/c it's by a highway(and just got established)) and am hoping it is bether than a stock pipe with the bafel removed. will this be better than the stock muffler w/o bafel?

Also will the way Spadtothebone.com seed to make it work? and this would be unreversable if i did not like the results right?
