Stepped Header Design - Exclusively from SuperSprint

A few weeks ago, we introduced SuperSprint's full modular exhaust for the F430. The F430 is plagued with a poor OEM header design. As true innovator, SuperSprint researched, developed and tested various header configurations to finally release the system that produced the most power. These headers were designed to be paired with SuperSprint 100CPSI HJS cat pipes or catless pipes.

Advantages and specifications of the stepped design

The pipes closest to the flange are 40x1.5 mm, to match the size of the exhaust ports, then they become 45x1.5. The advantage is that you don't have a step on the flanges for a more linear flow for better torque at low rpm, then you have less backpressure thanks to the bigger pipes and this allow better performance at high revs.

This design is ideal on cars with small exhaust ports and wide rev ranges. SuperSprint used it for BMW M3 E46, Nissan 370Z, Ferrari F430, Porsche GT3RS 3.8 and Lotus Elise/Exige SC and produced significantly more power than with regular tubular headers.

Advantages and specifications of the US/EURO PATENTED spring loaded merge collectors

1) Thermal expansion: AISI 304 stainless steel has a consistent thermal expansion factor, and the pipes tends to extend along their axis. With the 4 into 1 header deisng, the primary pipes follow very different paths but with the same length, if the header is welded, there would be critical tensions (both on the collectors and on the flanges) when the pipe that has a "straight" path push (the farthest cylinder from the collector) and the one with the more curved path pull (or push less).

With SuperSprint's system the pipes are free to expand and the leakage are avoided by the springs system. Even in the case of a seal failure, thery are inexpensive and easy to replace. Instead if a single piece header cracks, it has to be removed and welded. Also, leakage on the head flanges are more dangerous than some on the collectors, both becase of the position and because temperatures and pressures are higher.

2) Ease of assembly: SuperSprint's headers are much easier to be fitted on cramped engine bays like the F430.

About Supersprint

The engineers at Supersprint realize that for maximum performance, exhaust development must begin at the exhaust ports of the cylinder head. This is why Supersprint has the largest variety of racing header systems in the world today. Each header incorporates CNC laser cut port matched flanges. Primary tubes are mandrel bent using the latest CNC tube bending equipment. With special tooling Supersprint has been able to keep weld joints to a minimum for added reliability.

The fully appointed R&D department uses the latest in prototyping equipment along with the reliability and accuracy of a MAHA "all wheel drive" chassis dyno. With over 50 years in performance exhaust development they have earned the confidence of many of Europe's most respected tuners. Most units are 100% stainless steel.

We have one of these still in stock.

 

The patented merge collector design has been in effect for over a decade on various cars including Ferrari 355s, 360s and 430s with zero leakage issues and effectively increased reliability over the stock headers.

The concept is researched, developed, tested, patented and has stood the test of time and is SuperSprint's optimal merge collector selection where it is required and/or permitted by space constraints.
