sorry...you'll have to check on different companies that make exhaust add ons for your car...they're all different. mine won't work for yours...although this is what i have for mine (and make sure if you do find them, that you go with a resonated chamber to remove the 'rasp'...unless this is just a Z thing). keep in mind, though, that removing the catalytic converters isn't legal. heh.
check out a good forum for saabs. i belong to an incredible Z forum, and there are tons of marketplace vendors, DIY sections, and info for just about anything that can be done to a Z.
