Muffler be to loud for horses in trailer?

I pull a singe horse trailer with a dual bumper outlet magnaflow on my dakota 5.2, it's noticeable when your on it but not obnoxious outside at all. With the horses, usually the front of the trailers are solid while the sides are open so that will block alot of noise as well. Not to mention, how often are you flooring it while pulling horses??? :mrgreen: don't get the flowmaster because when you downshift trying to go up a hill or something, your ear drums will be ringing from the resonance, unless its a 50 series SUV those are nice. Get someting like a dynomax super turbo they're cheaper and sound great!
