Murchison WK2 Hi-Flow Exhaust System

Our exhaust not only delivers over 12Kw at the tyres by simply installing it, but sounds sensational and looks amazing. The quality and craftsmanship is second to none, we guarantee you will not find a better exhaust whatsoever for the WK2.
This kit requires professional installation by an exhaust shop - it only has 1 weld on
section at the DPF - simple task for an exhaust shop - but not recommended at all for a home install. The flange we supply must be internally tig welded in. We allow a 2-hour install, from start to finish.

Murchison WK2 XL Intercooler

In conjuction with the designers from PWR, Murchison Products brings you our HD Intercooler for the WK2 CRD.

The WK2 CRD runs a high factory boost setting which is only mildly controlled by the stock intercooler. We noticed that during data recording session the stock intercooler loose efficiency when higher revs and towing conditions are placed upon it, so we've designed a intercooler that is not only ten times stronger physically than the stock unit, but is more than three times the size!
This allows for
amuch improved air to air cooling capacity which lowers intake temps and thus allows us to run a higher boost in our ECU tune for safer running temps - at also lowers the EGT temps by over 100C.

Installing the intercooler will yield gains alone and doesn't require a remap of the ECU, but it is the best compliment for an ECU tune so you can take full advantage of the tune file.

Murchison ECU Performance Tune

• EGR is turned off in all tunes
• All tunes provide a punchier, harder accelerating drive and return better fuel economy numbers than stock.
• We offer a stage 2 flash for vehicles equipped with proper turbo back exhausts and/or intercooler upgrades
