HHR now offers primary cat delete downpipes for the 958 (2011-2017) Cayenne Turbo, Turbo S and the new V6TT GTS. The primary cat is replaced with straight through 3" downpipes.

These downpipes reduce the backpressure from the turbos and allow your turbos to spool nearly instantaneously, getting your Cayenne into the power band quickly. In addition, the downpipes increase low-end, mid-range and peak horsepower and can expect to see an approx. 40 hp, 40 ft. lbs. of torque gain from this bolt-on item without an ECU tune and even greater performance after an ECU tune. Please note that a "check engine" light may occur with these downpipes, so a custom tune is recommended to adjust for this.

The primary cat deletes/downpipes are handmade in Denver, Colorado. The tubing and flanges are made from 304 stainless steel. We use a 3" 16 gauge mandrel bend tubing which mates up to the turbos and secondary cat. The flanges are 3/8 inch 304 stainless steel, CAD-designed to match Porsche specifications and are precision waterjet-cut in our own facility. We include 4 O2 sensor fittings, similar to the factory setup. 

This is a complex installation, since unlike the 955/957 cars, the 958 downpipes include hanger tabs and the o2 locations are more difficult to access. However, this can still be a DIY project. Plan on approx.. 7 hours for installation for a beginner.
