Please Note: When cleaning exhaust tips, especially the blue tip variants which are made using a heat treatment process which can be removed with aggressive cleaning agents, make sure to use water and only if necessary, a very gentle soap. Never scrub, or use any rubbing or cleaning compound on these tips as the color will be damaged and will not be warrantied.

Stock catalytic converters prioritize emissions over performance, creating unnecessary backpressure that holds your engine back. Our performance catback exhaust eliminates this restriction, replacing it with a high-flowing design that minimizes resistance. Less backpressure means better airflow, stronger acceleration, and a more responsive ride—letting your engine breathe the way it was designed to.
