I've just purchased a '04 Daytona Blue Enth. Unfortunately I'm living in Italy for another 2 months or so and I won't get my hands on my car until I get back home to TX. My question is this, has anyone ever heard of this TopSpeedAuto company based out of Addison,TX? They make an aftermarket exhaust, the Pro-1 Performance Exhaust, for the Z. I've heard a clip of it and I absolutely love the sound. The purchase price on their website is not too bad but I know nothing of the company or their reputation. This exhaust is not 'true-dual' and utilizes the factory Y-pipe. I'm more than welcome to any and every suggestion/comment/advice.
