Title: Mufflers from Atwoods
Post by ralfyguy on 03/26/11 at 15:54:56

I went to Atwoods today to get a pole saw and went through the store and stumbled across the tractor repair section and there were some cheap mufflers in different sizes and diameters. I found a couple with the right diameter pipe and wheels and gears began to spin in my head and really got carried away with my fantasy... ;D
Of course they had no tabs or anything else looking like a bracket on it, but hey for 20 bux?? The only thing that kept me from getting one is the fact that the exterior looked ugly, and I am not into the rat bike look.
I got the stock exhaust and I do like the look. And the baffle is out, and the sound isn't all that bad. It is just a little high pitched for my taste. It IS loud though, especially when wrung out, but I like that. I just wish the tone was a little lower, like the Vance and Hines pipes my brother in law has on his C50. His bike sounds intoxicating good. His bike has the best sound I ever heard. I wish there was a Vance and Hines pipe for my S40, I'd buy it in a heartbeat.

What do you guys think? Would that be doable?

I did a Hartman muffler mod a few years ago. I didn't take pictures but if you go to

http://jonline.org/savage/Tips___How-to_s/Hartman_Muffler_Mod_Details/hartman_muffler_mod_details.htm

you can see details. There are a couple of different stock muffler baffles. My bike is a 2003 and the muffler was as illustrated at the bottom of the page in the link above. I used a circle cutter to cut out the baffle unit. Instead of separating the two baffle parts and then replacing the pipe with the holes in it, I just discarded the entire unit. I then fabricated a 1/8" thick aluminum disk with the center whole the same size as the original exhaust hole and fastened it with 4 large aluminum rivets. I made the fit as perfect as possible to prevent edge leakage. I didn't use any fiberglass packing.

You can see the finished mod in this picture:

I turned the mixture screw out a turn or so but no other changes. It runs well and sounds great.

I experimented with a couple different hole sizes but settled on the original size for back pressure and it just sounded the best. Nice fat sound with no whistles etc.
