my 89 240 came with some exhaust when i got it from the junkyard.
all i know is that its made in mexico. and it has this really deep and sexy tone like barry white. basically i've never seen anyone else with this exhaust so i'm guessing that it was some custom job done by the folks down in mexico. so its gotta be a genuine m.d.m. product. I'm thinking about selling it on ebay for a low price of $400 or so. pm if you're interested, i might be able to give forum members a special discount. this aint your N1 coffee can muffler folks, its a genuine hand made mexican exhaust system.
