Product Description

Elevate the sound and performance of your Porsche 911 with this lightweight titanium valved exhaust system by Rennline. Designed for enthusiasts, it features dual vacuum-actuated valves that let you control the exhaust note instantly. When closed, it delivers a sporty enhancement over the stock sound. Open the valves, and you'll release a deep, race-inspired roar during acceleration, accompanied by an exhilarating rasp on deceleration that’s sure to send chills down your spine. Best of all, there’s no drone or harsh tones—just the pure, balanced music of your engine.

This exhaust is a direct bolt-on replacement for vehicles with dual header-to-muffler flanges, allowing for a seamless installation and easy reversibility to stock. While the factory exhaust weighs approximately 25 lbs, this titanium upgrade comes in at just 12.88 lbs—saving you over 12 lbs while transforming your driving experience.

Product Fitment:

• 1965-1973 with early style headers/heat exchangers
• 1974-1989 with retro-fit early (1965-1973) style headers/heat exchangers

Not sure if it fits? The center-to-center measurement for the muffler inlet is 22.875".

Upgrade your Porsche’s sound and shed weight with this ultimate performance exhaust!
