Stepped Design Headers

Upsized, stepped headers are perfectly suited for the S54's long duration cam with lots of overlap. 

60mm v 63.5mm

The 60mm are designed with flanges for the OE cats, whereas 63.5mm require Supersprint's section 1.

HJS Motorsport Catalytic Converters.

They use a stainless steel catalyst with a 100 CPSI for optimized gas flow, positioned further downstream to reduce operating temperatures.

Hardware notes

As a rule of thumb, Supersprint does not include installation hardware. You will need to source new gaskets and bolts if you wish to replace them.

Build Journal: Special Series
The rasp, and the restriction.

2001 was an era where Americans had catalytic converts and Europeans didn't.

As CSL airbox conversions, cams and tuning were unlocked, new levels of power were found within the S54.

The exhaust became a bottleneck. Times does its time: technology and expertise evolves.

In this Special Series, I document sourcing, fitting and experiencing the 63.5mm Supersprint complete exhaust system.

Enjoy,
- Matt
