This cast downpipe features a twin HJS high-flow catalytic converter configuration, engineered to provide maximum exhaust flow without triggering a check engine light (CEL). With a 3-inch diameter, it ensures significant reduction in backpressure, enhancing turbo spool and overall engine responsiveness. The use of HJS motorsport-grade catalysts guarantees durability, efficient emissions control, and compliance with stringent performance standards, making it ideal for both track-focused and high-performance street applications.
