I put a Motad set of stainless steel downpipes on mine.
The Motad replacement header system outlet pipe is has a clear open area of 1364sqm. Whereas the original outlet is restricted to somewhere between 962sqm and 1075sqm.
When I fitted the Motad headers the power band almost evaporated and a gas analyser showed it be running far too weak, this being supported by the plug colour.
A further test was done by a lazer temp gauge on the exhaust clamp bracket of both original and new pipes and this showed the exhaust gas temp had risen.
To solve the issue the Motad pipe was sleeved down first to 1075sqm which improved things no end, and finally down to 975sqm, which seems to be better.
Plugs were checked and exhaust gas analysed and the results were as good as I could get them.
