We only use the finest stainless steel and expert welding so we guarantee a superior product.

Bimodal exhausts are a huge modification in the performance of the exhaust systems and the use of intake and exhaust valves.

  • Basically a Bi-modal allows the valve to remain open when active and then return to a quite note when closed. *Please note at WOT with exhaust shut slight whistle.
  • Bimodal exhaust systems are much more complicated than ordinary aftermarket systems, with exhaust flow taken into account with the exhaust open and closed.  (With the Uni-x ECU control, you can have RPM controlled open shut and partial open also.

Dynomotive Built Nissan Patrol Y62 Exhaust Bi-modal features include: –

  • Bimodal motor, which controls the butterfly valve defining the amount of exhaust gases passing through the muffler.
    • It is either on or off. (With Exhaust E.C.U non Uni-x application.)
    • With Uni-x Control, It will also have the ability top be partial open/closed, and operate via RPM. Eg: Closed until 3000rpm or Open at idle, shut until 4500 rpm then open.
    • With the Uni-x you will have integrated Can bus switching via the factory maps, allowing the driver to choose between normal, sports mode or combined.
    • Stainless Steel, with Centre Muffler and rear resonator.
    • Systems designed & manufactured here in Bayswater Vic.

  • ‘Cat delete pipes for off road and racing only’ 
  • ‘If vehicle will been driven on the road the system will have exhaust emission in place.’
  • Exhaust mode “closed” may give you a whistling noise at high RPM, it is recommended to open the exhaust to avoid this.
