Fabspeed Porsche 911 Carrera Exhaust for SSI Style Headers 1965/74'-1989 model years

Fabspeed Maxflo X-Pipe Exhaust System for Porsche 911 cars worldwide with Porsche style dual outlet headers & SSI brand headers for model years 1965–1989 model years. 

Give your classic air-cooled Porsche 911 the performance, sound, and craftsmanship it deserves with the Fabspeed Maxflo X-Pipe Exhaust System. Designed specifically for 1965–1989 Porsche 911 models equipped with SSI-style dual 2-bolt headers, this system replaces the restrictive factory "banana" muffler with a modern high-flow X-pipe design that dramatically improves exhaust scavenging, horsepower, torque, and throttle response.

Engineered entirely in-house using advanced CAD technology, the Maxflo X-Pipe precisely merges the left and right FLAT-6 cylinder banks through our proven crossover architecture. This optimized exhaust flow improves cylinder scavenging, allowing the legendary air-cooled flat-six to breathe more efficiently while delivering stronger performance throughout the RPM range.

The result is an unmistakable Porsche exhaust note—crisp, mechanical, and aggressive—bringing out the authentic character of the classic flat-six while maintaining the timeless personality enthusiasts love.

Constructed from premium T304 stainless steel, every Maxflo X-Pipe is precision CNC manufactured, TIG welded, and built to withstand decades of spirited driving. The complete bolt-on system includes everything required for installation and is designed for excellent fitment with SSI dual-header-equipped vehicles.

Whether you're restoring a vintage 911 or building the ultimate driver-focused air-cooled Porsche, the Fabspeed Maxflo X-Pipe offers modern exhaust technology without compromising the soul of the original car.
