I tried to tuck the mufflers up underneath the body as tightly as possible, and I'm wondering if I've overdone it. They're only about an inch or so from the floorpan, and when I finally got my engine fired up and ran it for 10 minutes or so, the floor sure was HOT. Granted, I only had a single layer of dynamat without carpet yet and I would think that when the car is moving then it would cool it off somewhat, but should I move them down lower or use some thermal wrap? I'm definitely going to double up on the dynamat in the back seat area now.
