how could we possibly forget the CES exhaust :D We'll I've seen the CES system for the Corolla Sportivo and the other items they have just finished off for the Sportivo and I have to say that the quality is second to none and from the experience I have in the auto industry CES have prolly the best reputation around for the stuff that delivers the goods. I Don't have a Sportivo but have a Honda that has had the "CES" treatment and I have to say that for those of you who think CES is too dear you only get what you pay for.... and that's a quality product that does what it's meant to. As you may have noticed I'm a happy customer of CES :D
