HHR now offers its 3rd variation of its secondary cat bypass for the first generation VW Touareg V8 (2002-2010). The stock Touareg has 2 sets of (4 total) catalytic converters and this bypass removes the rear set of cats (you will still have one full set remaining on the car) to increase HP/TQ and to provide a performance "Euro" sound.
We hand manufacture our own bypasses in Denver, Colorado. The tubing, flange, and 4 adjustable hangers are made from 304 stainless steel with a brushed finish. We utilize a 2.5" tube which mates up to the factory down pipe, then to the factory midpipe. Our flanges are 3/8" 304 stainless steel, CAD-designed and waterjet-cut in-house. Our bypass also incorporates 4 adjustable stainless hangers. While the bypasses are considerably lighter than the factory cats, hangers are mandatory because the factory downpipes are flexible braided stainless steel and are not designed to be weight bearing. Adding bypasses without hangers will eventually damage the factory downpipes.
Based on customer feedback, bypass pipes provide immediate power gains throughout the powerband with peak gains up to 15hp to 17hp.
We believe this is a DIY project for anyone capable of operating a wrench. We provide detailed instructions, needed hardware and copper gaskets. This project is estimated at 2 hours depending on the condition of your factory hardware. Corroded/stuck factory studs/nuts can increase installation time.
