The factory over axle pipes on the naturally aspirated 718 4.0L cars contain dense particulate filters that restrict exhaust flow and significantly mute the sound and character of the engine. SOUL Competition Over Axle Pipes replace these restrictive factory sections with a free-flowing, full 2.25-inch stainless steel design, reducing weight and allowing considerably more of the 4.0L flat-six exhaust note to come through.
Unlike SOUL's Resonated Over Axle Pipes, the Competition OAPs eliminate the factory particulate filters without adding resonators back into the exhaust path. The result is a more direct and aggressive increase in exhaust volume and character. For owners looking to maximize sound while retaining the factory headers and rear exhaust—or building a more aggressive complete exhaust system—the Competition OAPs are the more performance-focused choice.
At just approximately 12.3 lbs for the pair, the Competition OAPs remove approximately 10.9 lbs from the rear of the car compared with the 23.2-lb factory components. SOUL's one-piece construction, large-radius mandrel bends, and precise fixturing provide a true bolt-on upgrade suitable for both street and track use.
