We've got a pair of HD4's that both have mufflers/stacks that are only getting about half of the exhaust out of the engine compartment, the rest of it blows madly about under the hood. Figured it's time to fix it on both, and was wondering if anyone here had any experience with a simple neat way, or any advice on what they've found works to redo the exhaust on these machines.

Thanks for the help!
