I don't get it either. But I HAVE made believers out of the So Fla locals. One of the guys down here has a '01 5-speed sedan whose only mods are desnorked intake and a Stromung exhaust. He was extremely impressed when I followed him home one day and stayed right on his bumper through some spirited street driving, both straight-line accelleration and cornering. Now he sings the fat-boy praises.
Of course, I have a lowered suspension with every strut bar known to man, and I have a K&N drop-in and a Borla gen 3 header, and now I have an RS muffler. But mine's an automatic. I still stayed with him, even with a 10% heavier vehicle.
