Euro Sport performance exhaust systems are designed and manufactured with the performance enthusiast in mind. We use an increased diameter of mandrel bent aluminized steel tubing in Euro Sport's designs to ensure maximum flow and horsepower. Euro Sport's systems will give you a 7-12% horsepower gain along with a sporty, track tone. All systems come with resonators and Euro Sport's exclusive mufflers, which feature a Stainless Steel straight through perforated core for smooth unrestricted flow, lap jointed all weld construction, stainless steel mesh packing and high temperature acoustical absorbing material. For added convenience, we also include the necessary clamps, hangers, and instructions for installation. All Euro Sport exhaust systems come with a two year limited warranty. Fitment: MK2 Jetta 8v Note: On 8v cars please specify if catalytic converter outlet is 45, 50 or 55mm.
