Since your converters are built into your Y pipe, you would need an exhaust shop to fab up some custom pipes to bypass your converter. If you want to check your converters backpressure you can purchase a pressure gauge that threads into your o2 sensor bung.

How can removing a restriction in the exhaust such as a converter, cause more backpressure. As long as you are running a muffler your torque should not be affected in a bad way. Your power and fuel mileage should increase.
