Downpipes (3-inch) for Audi Q7 & Q8 Porsche Panamera & Cayenne & Volkswagen Touareg with 3.0 TFSI 2016+ engine.

Sport catalysts (Mitex). The pipes can be ordered with Mitex metallic sport catalysts welded in - pick the version in the options. The marking reads as follows: E3, E5 and E6 is the emission standard the element is built to (Euro 3, Euro 5, Euro 6) - the higher the class, the denser the washcoat and the cleaner the exhaust; the number that follows (500, 750, 800, 900) is the power the element is rated for, in horsepower. Higher-rated elements have a larger flow section, so choose the one that matches your current or planned power level. All versions keep the OEM sensor bosses, are TIG-welded into the pipe and work with the stock ECU - no check engine light and no raw exhaust smell, with far less back pressure than the stock converter. The "without catalyst" version is a de-cat pipe intended for off-road / track use only.

Heatshield wrap and race catalytic elements (eu3 eu5 eu6) can be added to the pipes for extra charge, the diameter of pipe or flange can also be changed according to your request, leave a comment to the order at check out.
