Product Description

The Fabspeed Porsche 997 Carrera Sport Cat X‑Pipe is a high‑flow, performance‑driven exhaust upgrade engineered for Porsche 911 Carrera (997.1; 2005–2008) models. Replacing the restrictive factory catalytic converters with high‑flow 200‑cell HJS Sport catalysts and a mandrel‑bent stainless steel X‑pipe, this system dramatically enhances exhaust flow while retaining emissions scrubbing and preventing check engine lights. The X‑pipe design improves exhaust scavenging and delivers a deeper, more aggressive flat‑six tone with increased volume and smooth mid‑range power delivery. Dyno results validate measurable gains in horsepower and torque, making this upgrade ideal for enthusiasts seeking both sound and performance from their Carrera.
