Well, for the few years I've owned my Corrado I always thought it had an Autotech aluminized cat back exhaust. I started hearing a leak in it and crawled under the car to take a look. From what I see now it is an Autotech stainless resonator back exhaust with a Liestrichz (sp?) center resonator. I think the resonator tube is where the leak is. Does anyone know if one of the Techtonics straight through stainless resonators will fit to the Autotech exhaust?
