NOTES:
HJS German imported catalytic substrate cores are made by EMITEC utilizing the highest grade stainless steel materials and Tri-metallic precious metal wash coats for high performance street and racing competition usage. HJS German 200 cell Trimetallic Euro 6 HE catalytic converters give the highest performance gains, improved sports car sound and maximum durability. Other brands of catalytic converters immediately deteriorate and fail over time as is typical. Some other companies and brands DO NOT even offer catalytic converters as they know that their catalytic converters will NOT work even when 100% brand new as they have no reliable quality solutions. The HJS German imported HD catalytic converters flow up to 90-92% 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. Typically no P420 and no P430 codes and your car smells clean with no need for a tune to pass emissions testing. It's a win win solution for a sportier sound, more power, and a cleaner running car which prevents pollution. Not all HJS catalytic converters are the same. Size matters and directly correlated to power, sound, and durability. Fabspeed utilizes the LARGEST possible HJS Catalytic converter for maximum power and sports car sound. No short cuts ever.
