Catless Downpipe for Porsche 95B Macan S 3.0T

The Stone Exhaust Q224P is a catless downpipe engineered specifically for the Porsche 95B Macan S (G2) with the 3.0T engine, model years 2019 and newer. This component is crafted using a one-piece mandrel bent pipe design and benefits from advanced manufacturing techniques, including mechanical welding arms that precisely weld to prevent ash generation within the pipe wall. This innovative process minimizes vapor lock and enhances exhaust efficiency, leading to optimized performance from the exhaust turbine. Stone Exhaust utilizes state-of-the-art 3D scanning and simulation software in their research and development process. By analyzing OEM parts, engineers identify potential weaknesses and optimize factors like pipe diameter and bending angles. The use of a 7-axis CNC bending machine ensures exceptional precision, maintaining an impressive 98% roundness and minimizing airflow obstruction. The flange connection between the turbo and downpipe is strengthened with crisscross and overlapping welding techniques to withstand extreme temperatures (800℃ to 1100℃), increasing endurance and reliability. Key features of this downpipe include a catless design, a flex design to prevent breakage from extreme heat, and a Plug and Play OBDII controller. It also boasts a crisscross welding technique to strengthen the turbo flange, a one-piece design, machine welding, and 100% OEM fitment. The product comes with a 2-year warranty from Stone Exhaust.
