OH MY GOD!!!!!!! An inport/rotary class!?!?!?! Are you kidding me????? That's the last thing we need. I don't think those things could sound any worse if you tried. I thought the NHRA had a muffler rule on Sportsman race cars. I think they need to make a stop at Sunshine and enforce it a little. Someone should tell those guys to put a muffler or two or even three on those things. They sound like ass!
