    I went with Xtreme Flow myself. I think they were the cheapest for flowing the most volume (CFM). I think the model # was XF-12 their website is xtremeflow.com...Zed

    Hey lance go with carsound cats. you can get them at MTI and they say those are the most free flowing cats there are, but i think random tech bullet cats flow the best. Good luck.

    How did you tell one was bad? I'm convinced that my driver-side one is stopping up.
