The Saab 900 Turbo 3 inch Mild steel Exhaust System is a quality aftermarket upgrade designed to improve the performance and sound of your vehicle. This specific kit does not include a catalytic converter, allowing for a more direct and unrestricted flow of exhaust gases. With the larger 3 inch diameter, this system is sure to provide a deeper and more powerful exhaust note, used item so showing sign of rust (check phots )but is solid. Possibly made by Jetex?
