Exhaust note to one person is not felt the same way as to the guy next to him at the cruise-in. I can drive around my whole town without missing a single street before my duramax gets to temp. The cars will warmup by the time halfway through that process. We have a cruise here every year, and a pile of cars make the trip. Right around 45-60 cars. Many steady Eddies return every year. Others have work commitments they cannot get out of. Point here is, my car barely gets to op temp before the hill that takes me out of town. Then it's a 45-50 mile trip chock full of whooptydoo's and yellow signed 25-30mph corners. It has approximately 3 miles of passing lane during that time. My 8 cylinder cars rarely ever change gears throughout the whole trip(unless I "need" to pass a boat...) as the cornering is the favorite part. Picture a 50 mi road with 30 mi of corners, lined with sharp and jagged rocks on one side, and cold deep and wet on the other. Mufflers that can't let me hear how tires an suspension are faring rarely last long on my cars.
