Overview

The M4 Exhaust KA6994 is a full system exhaust with a carbon Street Slayer canister. It removes the stock catalytic converter.
Show original supplier description
The M4 Exhaust KA6994 is a full system exhaust designed for the Kawasaki Ninja ZX6R, featuring a carbon Street Slayer canister. The Street Slayer mount provides a sleek, short aesthetic while maintaining a tolerable exhaust note. Constructed with stainless steel tubing, this system is built for durability and performance. It directly replaces the stock catalytic converter, contributing to enhanced exhaust flow and engine performance. For those seeking a quieter operation, the Stage 1 Q8 Quiet Insert and Stage 2 Q6 Quiet Insert are available for separate purchase. This full system is specifically designed for 2009-2025 Kawasaki Ninja ZX6R models. It's important to note that this exhaust does not meet emission requirements for street or highway use. To ensure optimal performance and to clear potential check engine lights related to the servo motor, a tune is recommended, and the servo motor may need to be deleted or bypassed using a servo buddy.
