These C8 Corvette ZR1 Sport Cats from Fabspeed Motorsport replace the factory catalytic converters on your twin-turbo LT7 with a pair of German-made HJS 200-cell tri-metallic sport catalysts.
The result is a deeper, more aggressive tone, quicker turbo spool and real power gains, while staying on the right side of the check engine light.

- Pair of German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters, each rated to 1,200 HP.
- Weight savings of 20 lbs / 9.1 kg compared to the stock catalytic converters.
- Constructed from T304L stainless steel, back-purged TIG welded for durability.
- Insulated with 2000°F ceramic fiber wrapped in a 625 Inconel double-wall heat blanket.
