Review FLOWMASTER Exhaust System Kit 68 Pontiac fits LEMANS 1972

The Flowmaster L161921 Exhaust Kit is a high-performance aftermarket exhaust solution designed specifically for the Pontiac Lemans produced between 1968 and 1972. This exhaust system is engineered to deliver superior power gains, enhanced engine responsiveness, and an enthralling exhaust note that is the hallmark of Flowmaster's reputation.

This exhaust kit includes all necessary components for a complete replacement of the stock exhaust system. It features 18-inch long, 1.625-inch diameter mandrell-bent stainless steel headers. These headers are designed to provide efficient exhaust gas flow, reducing back pressure and allowing the engine to breathe more freely. In turn, this results in increased horsepower and torque.

The mid-pipe section of the exhaust system is also crafted from mandrel-bent stainless steel tubing, with a diameter of 2.25 inches. This component connects the headers to the muffler, ensuring a smooth and unrestricted exhaust flow. The muffler itself is a Flowmaster 40 Series unit, which is known for its impressive sound quality and performance. It utilizes a unique internal design that maximizes exhaust velocity while minimizing back pressure, resulting in a deep and resonant exhaust note.

The exhaust system also includes stainless steel resonators and tailpipes, which further contribute to the system's performance and sound qualities. The tailpipes measure 3 inches in diameter and feature a polished finish to add a touch of elegance to the vehicle's exterior. This exhaust kit comes with all required mounting hardware, gaskets, and clamps to ensure a hassle-free installation process.

By upgrading to the Flowmaster L161921 Exhaust Kit, Pontiac Lemans owners can expect to notice improved engine performance, a more responsive driving experience, and an exhilarating exhaust note that sets their vehicle apart from the crowd. This exhaust system is not only a performance upgrade but also an aesthetic enhancement to any Pontiac Leman.
