Our modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for track use. Rennkraft, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch4\u003eWhy We Choose HJS Catalytic Converters:\u003c\/h4\u003e\n\u003cdiv data-mce-fragment=\"1\" style=\"text-align: left;\" data-mce-style=\"text-align: left;\"\u003e\u003cimg data-mce-fragment=\"1\" style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2641\/0682\/files\/hjs-official-2_1_240x240.jpg?v=1611345818\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2641\/0682\/files\/hjs-official-2_1_240x240.jpg?v=1611345818\" data-mce-style=\"float: none;\"\u003e\u003c\/div\u003e\n\u003cbr\u003e\n\u003cp align=\"justify\"\u003eHJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the \"straight pipe sound\" while still being able to provide enough emissions scrubbing to prevent a check engine light.

Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and deceleration burbles are more robust and transparent. With the cat bypass pipes installed, you’re in store for a sound much more akin to a 911 CUP car than a Porsche street car. The volume isn’t overbearing, but the sound is very aggressive and race bred. It totally changes the character of the car. With the stock muffler in place, there is no drone what-so-ever, even with our Over Axle GPF Delete Pipes also installed.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch4\u003ePower:\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThese headers will add more power than any other single bolt on part.
