Quiet PTO-Canister Muffler & Guard Kits (Ideal for Gen Sets)
Mufflers are same size as std. canisters (Top of page), but are 2-3 dBA quieter.
They also have a raised-body design to clear the alternator assembly on a generator set.
Note that there is no center oulet muffler because it would allow hot exhaust to blow directly at the gen set control box.
