I went to my longtime exhaust guy, and asked for his opinion on a simple muffler swap. He said he liked Donaldson, and Allied. He only had the 24" Allied in stock, so I opted for it. He figured it for somewhere near a 7hp. gain, if actually dynoed. It is louvered thru core muffler. The sound increase is very slight, with no resonance in cab. From a performance standpoint, it is detectable. Most notably when starting out, and at cruise speed. There just simply seems to be a slight increase in responsiveness. He personally thought the stock system minus the muffler was a good design. It was just short of $200 installed.
