Is there a problem with your exhaust system? It should last a lot longer than 2 years. If you're hoping for a "performance" system, you'll likely have to get someone to custom fabricate it for you. Gains would be minimal...you might eke out an extra 5-7% power on the high end of the RPM band if you also got aftermarket high-flow catalytic converters.does anyone know if any aftermarket exhaust companies are going to make an exhaust system for the 2011 sorentos? or would it have to be custom made?
