you know what, thats true to an extent... i love the 2zz motor, and i think the sportivo is a very good performing car, but at the end of the day, you're driving a corolla... and whiles its great because its got a nice mix of performance, and fuel economy, and family-car-ness, its not a high performance car, and its not really designed for the 1/4, or the track. its designed to be driven around the streets, and there's the opportunity built in for some spirited driving... if people wanna spend the money on something they have been shown is better, why not go for it? if you're not keen on spending so much on your corolla, don't... but leave those guys alone who have, they just have different tastes and aspirations for their cars than you... if CES made a 1zz exhaust system that was nice and cheap, and it proved good gains, id buy it in a second... but im just one of those people who can't justify so much money on my car in that area...
