Murchison Ram 1500 Long Tube Headers


Unused headers imported from Australia for the DS model Ram 1500 RHD. I have sold my 2019 Ram so these performance headers are now available.

Custom made via CNC bending and jig welded for repetitive perfection, the MP Ceramic Coated headers are all Australian Made specifically to suit the ASV Converted Ram 1500s.

ASV make without a doubt the best Ram 1500 DS conversions in the country. We deceided that due to the engine bay specific changes with ASV's conversion process, there was a need to make specific headers for them to clear the steering and new oil cooler / oil filter re route lines.


After testing the 1" 7/8ths tubes we settled on a slightly smaller 1" 3/4 design due to the torque charchteristics and fuel economy gains with the 5.7 Hemi. These headers are also a MUST DO when Supercharging your 5.7 Heim Ram as the stock super restrictive cast iron headers dont flow the required numbers, not to mention the potential of them to crack due to the heat cycles.

Murchison Products offer full in house fitment of the headers and they are a great compliment to our aspirated tuning and exhaust packages. Our Ram power pack upgrade which consists of Intake, Tune, Headers, Throttle Body and Exahust see a respectable 65KW gain at the wheels whilst all the while delivering fuel economy and torque gains. We have heard of other shops claiming 100Kw at the wheels with this level of mod tuning and all we can say is BEWARE! We wouldnt like to see the pistons and valve train after 20-30,000klms after such agressive tuning like that!

We have tested and tested with our own shop Ram, we have over 35,000km on our tune now and plenty of those with over 3.5t towing on board. Our tune can also take as low as 95 oct fuel should you be in an area that doesnt provide 98oct but of course 98 is preferred.

I paid over $3300.00 including exchange rate, shipping, duty and gst.
