Headers are a good way of improving gas flow from, especially a V8 engine which has firing pulses from adjacent cylinders interfering with each other. The most effective headers have equal length primaries, all of a tuned length - a good example is the GT40 system. The problem is trying to fit such a system in the 928 engine bay which is compact at the best of times.

​

Various people have produced 928 headers with 19" primaries which extend under the bellhousing. This then requires a custom section behind and usually involves a complete custom exhaust system which is very expensive and crucially requires removing the headers to get at the clutch or flexplate. 

​

Consequently I set about making a system which would fit to a standard set of downpipes or my X pipe and this is the result. All Stainless Steel with 4 into 1 merge collectors and a 'spike' at the merge to help gas flow, these headers are a tight fit for sure.

​

Fitted to the Ritech X pipe and with custom LH and EZK EPROMS (soon to be available) the system makes useful extra power and torque as measured on a rolling road by my own car which is a non ideal Automatic
