I'm thinking about removing my H-pipe and adding a Magnaflow DI/DO muffler (11386) to my exhaust. I'm curious how well these 4x9 oval mufflers fit under the car. I remember reading a post a while back where someone mentioned their DI/DO Magnaflow sat below the body a little. My car is pretty low, 2.5"-3" lower than stock, so clearance could be an issue. Anyone have any problems on their lowered car with one of these?
