SpeedART 325hp Power Kit II Porsche Boxster 987 05+

For a better sportive and sonor sound with more power speedART offers the speedART Power Kits. Theses kits are produced in Germany with complete TUV certifications. 200 Cell cats are used to ensure no error codes appear. speedART is using the single muffler because the sound is much smoother and does not resonate like the two seperate cans. The power gains are also much better with the single can. Includes Header, Cats, Filter, Muffler, and ECU Upgrade.
