Description
The Kooks 22603300 3″ Stainless Steel GREEN Catted OEM Connection Pipes provide a high-performance, emissions-friendly solution for connecting Kooks long tube headers to the factory exhaust system on the 2016–2024 Camaro SS and ZL1. Designed from durable 304 stainless steel, these connection pipes feature advanced GREEN high-efficiency catalytic converters engineered to support strong horsepower gains while minimizing emissions and exhaust odor.
These OEM-style connection pipes reduce to a 2.75-inch outlet, allowing them to bolt directly to the stock exhaust after removing the factory front section. The GREEN catted design helps maintain a cleaner exhaust and improved environmental efficiency compared to traditional high-flow cats, making them ideal for street-driven and tuned vehicles.
Whether installed on the naturally aspirated LT1 or the supercharged LT4, these Kooks OEM connection pipes ensure excellent exhaust flow, compatibility, and durability as part of a high-performance header system.
