I want to put a cat-back exhaust on my 1.8TQ. Would like feeback on Brullen, Scorpion, Supersprint, Hoppen and any others please. Power increase? Noise increase? Any negatives?<p>Thanks;

I can speak from experience on the Klasse and all I have received is compliments. I know that the tip is a bit intimidating at first, but it really does grow on you. As for the sound, it's a very soft rumble at idle. With the windows up you can just hear the throaty groan under load, but not when you are cruising. With the windows open the resonant freq seems to be around 2700rpm where the sound is at its loudest, though I do not find it intrusive. The turbo spools up much earlier now, 500-700rpm before where it was. I have cut over 1 second off from my 1/4-mile time with the exhaust and a .8bar chip. The power band is much wider and much, much more fun to drive. I have a contact for a great price if you want one. My brother owns a tuning shop and I have worked it out so A4.org users get a DEEP discounted price. E-mail me at the above add if you want more info.

Stephan,<p>Yes, please e-mail info to me at the above address. Thanks.
