    Default help with m813 exhaust

    can anyone help with my exhaust on my M813 non turbo? the muffler had rust through under the clamp that goes around it , and a hole in the elbow where it comes up through the finder. so i was going to patch the muffler by either welding it or using patch materal, but i was thinking of doing away with the muffler and using stainless flex pipe and re doing my battery compartment and runnung exhaust like the 900 series, has anyone done this or can give me advice so i dont jack up something or cause my self some more money, ?

    You're talking about eliminating the muffler altogether then? These trucks are LOUD already. I definitely wouldn't drive it without hearing protection if you do.

    The output flange on my muffler has broken off. I'll be replacing the muffler and sticking with the stock configuration and that's still going to be pretty loud.

    At least there's a muffler in that configuration. Your neighbors and ears will thank you.
