Two Brothers Racing 2-into-1 exhaust systems are engineered for maximum torque. They feature race-inspired stainless steel headers that shave pounds off the competition, ensuring an incredibly durable and weather-resistant exhaust with a powerful sound. Complete with heat shields, the exhaust flows from the engine through our 1 3/4" stainless steel pipe, which includes O2 plugs to accommodate both stock and 18mm sensors. From there, the exhaust flows to 1 7/8" before merging into the spring-retained header for increased torque. The exhaust then exits the header into a 4" diameter muffler for an unparalleled outgoing sound. Competition-S exhausts feature removable aluminum or carbon fiber end caps.
