Why We Choose HJS Catalytic Converters: 

HJS 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.    

Replace the restrictive OEM ceramic GT2RS 700 cell catalytic converters with ultra free flow HJS German Imported tri-metallic race quality 200 cell HD cores that FLOW 92% to 93% of  a straight pipe.  Fabspeed Motorsport USA is the Exclusive Importer for HJS Emissions technology Deutschland Germany for all of North and South America. We use the very best largest possible imported 200-cell HJS Sport Cats increase that immediately exhaust flow for better power and throttle response and improved superlative GT2RS dynamic sports car sound!

Simple direct replacement bolt on HJS katalysoren / catalytic converters for the ceramic GT2RS cats and integrate easily with the titanium OEM center muffler.  These are the very largest HJS HD German cores that will fit on this car. There is NOTHING Bigger or better than the HJS catalytic converter that Fabspeed Motorsport has supplied. Guaranteed 92% flow of a straight pipe with 100% no Check Engine lights no ECU tune required. Do get suckered in to any other brand of cheap aftermarket catalytic converters. Fabspeed also uses Helical U.K. imported 3.0" 74mm vacuum actuated exhaust valves. Helical LTD. Aerospace England supplies these ultra high temperature valves to Porsche, Ferrari, Mclaren, Aston Martin as OEM due to bulletproof reliability. If its NOT engraved with Helical on top it will FAIL, rattle or melt internally. If its not a Helical exhaust valve it will not work. 

Porsche used a small 60mm 2.375” exhaust valve for the bypass to the exhaust tip on each exhaust bank. Fabspeed Motorsport went much larger 74mm 3.0" valve for enhanced flow and utilized a the same larger, Therefore higher exhaust flow, Helical UK silica carbide  that Ferrari uses on the 488/ 488 Pista, F12 and Lamborghini uses on the Huracan, Performante and SVJ Aventador and Mclaren Senna.  Therefore your GT2RS gets the Worlds Very Best ultra quality exhaust valve in a larger size style  for more exhaust flow and sports car sound. Fabspeed engineering was the 1st company to enhances PSE exhaust on the GT2RS.

The above Fabspeed Motorsport GT2RS high-flow catalytic converter system is the World’s Very Best! This is the result of design, engineering and the very best globally sourced components.
