Hi one and all, I am looking at getting a muffler for my cat .The pipe is a "2" band - I goggled Octura chart-american r/c boats and gave me a listing of mufflers. I got to a set of (i think S/S -carbon) with 3 different sizes .620 - .545 - .505 can any one help me in-regarding size difference and is one better than the aether ? (this is to fit a mod 26 motor) .
many thanks
Marc
