The Vortex ExhaustTM Resonator overcomes the inefficiencies found in all conventional stainless steel exhaust designs including free flowing high performance stainless steel or titanium exhausts. Using the Vortex Exhaust Resonator means all rally racing performance engines run smoother and quieter and require less fuel than before to maintain constant output (maintain race cruising speed).
At the Chatsworth meeting in June 2008, apart from the class win another 1st to come from the meeting was the acceptance of the Vortex resonator in place of a diesel particulate filter (DPF), more info on performance exhausts.
Vortex ExhaustsTM are suitable for any internal combustion engine application, as they are made of stainless steel or mild steel, hence they produce performance exhausts:
Vortex makes the stainless steel exhaust work differently
Conventional exhaust systems, by their design, stifle engines. Exhaust pipes, silencers and catalytic converters rely on a build up of pressure to force gas out through the exhaust system. Consequently backpressure builds up in the exhaust manifold greatly reducing engine efficiency (can be up to 30% or more). By comparison, the revolutionary Vortex ExhaustTM Resonator vacuums exhaust gases out, vastly reducing manifold pressure and improving engine performance and efficiency.
Vortex mechanics are the key
The unique design of Vortex ExhaustsTM incorporates VORTEX MECHANICS – a system that swirls gas with no moving parts inside a central chamber. This turbine effect draws exhaust gas out at high speed, allowing the engine to breath and run more freely. The Vortex ExhaustTM Resonator has undergone 10 years of research and development, and has taken exhaust technology to a new level.
Vortex ExhaustsTM employ the patented Vortex ExhaustTM Resonator which unlocks power, torque and fuel efficiency, previously unobtainable from your engine. We have ample data to back up our claims. This vortex technology works with rotary and piston driven engines. The warranty period of our products for this application is 3-years. All products are manufactured inside and out from 304 (or 316 marine grade) stainless steel, to produce a performance exhaust.
