PFA Stainless Steel Long Tube Headers | Aston Martin 6-Cylinder Models
Unleash the full performance potential of your classic engine with PFA Stainless Steel Long Tube Headers. Specifically designed and fabricated in the UK, these headers bring racing-grade engineering to the heritage Aston Martin range. By replacing restrictive factory cast-iron manifolds with our precision-tuned headers, you provide your vehicle with the breathability it needs to perform at its peak.
Precision Engineering for Quantifiable Gains
To ensure optimal results, we leveraged our extensive racing experience to develop these headers for high-performance road use. Following rigorous dynamometer testing across a wide range of applications, we optimized the design to provide a substantial improvement in both throttle response and torque.
Specifically, on a 3.7-liter engine, our dyno tests revealed impressive gains over factory manifolds:
-
Torque: A significant 22 ft-lb increase at crucial points in the rev range.
-
Horsepower: An 11hp uplift across the entire powerband.
Furthermore, these headers are highly versatile. They are engineered to perform exceptionally well with engine capacities ranging from 3.7L to 4.2L and are fully compatible with both SU and Weber carburetor setups, including Vantage models.
Seamless Integration and RestoMod Appeal
While performance is the primary focus, we also prioritized aesthetic and practical integration. These manifolds significantly improve the visual appeal of your engine bay—a key consideration for Aston Martin RestoMod enthusiasts.
Regarding installation, please note the following technical details:
-
Compatibility: These headers fit both Right-Hand Drive (RHD) and Left-Hand Drive (LHD) configurations.
-
Hardware: They are supplied with downpipe flanges and are compatible with all factory engines and gaskets.
-
Fitting: Consequently, the downpipes will require slight modification to ensure a perfect, leak-free seal.
-
Finish: This listing is for a pair of uncoated, plain stainless steel manifolds. However, we can supply ceramic-coated or insulated versions upon request for an additional cost.
