This axle-back exhaust system is manufactured entirely from titanium. This makes this system ideal for cutting weight while being structurally stronger than the OE exhaust system. The engineers at Akrapovic have retained the dual mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car. The included exhaust pipe tips are made completely from titanium OR a carbon fiber/titanium composite to add a high-end, refined style. Performance has not been left out of the design. The system dramatically reduces backpressure and is an excellent starting point for further engine tuning or turbo modifications. Even when installed on an otherwise stock vehicle a gain of 7.3 horsepower and 17.4 Nm/12.8 lbs-ft of torque are achieved. Furthermore, a weight reduction of 3.0 kg/6.6 lbs. is realized. The OEM catalysts are retained, so no reflashing of the ECU is required and the check engine light will not be triggered. Titanium muffler with integrated exhaust valves Statistics: +7.3 HP (at 4400 rpm) +17.4 Nm/12.8 lbs-ft of torque (at 2350 rpm) 3 kg/6.6 lbs. lighter than stock Not for sale outside the US or Canada.

Over time, has the cap for your oil filter housing become harder to remove? Using the wrong tool can round the top of the cap, making removal harder each time. Replace your old cap and seal to ensure your engine is leak-free. We recommend pairing this with the Schwaben Oil Filter Cap Tool (T#371924) to make installation and removal easier.
