HONDA NSX MUGEN EXHAUST MANIFOLD

Honda NSX Mugen Exhaust Manifold

Here is some literature for those that are interested, those that cannot be bothered, keep scrolling. Please excuse the Japan-a-glish, it was directly translated from Mugen Japan. >>

What is required for the development of the exhaust manifold is having equal length of pipes and perfect exhaust gas flow. On the dynamometer bench test, the pulsation, resonance and inertial effect of the exhaust gasses emitted from each cylinder in addition to the connecter’s position of the primary, secondary, and collector as well as the pipe’s diameter were studied to find out its optimum layout by delicately adjusting each length of the exhaust pipe and repeatedly making and trying the different configurations.

Furthermore we would like to recommend High-Performance Engine Oil VT-α, which fulfills the hidden potentials gained through MUGEN manufacturing technology. This engine oil is 100% chemically compounded oil of SAE 5W-40 developed through repeated bench tests to be suitable for the Honda VTEC engine. High specification engine oil possessing proper viscosity; and with newly developed additives (MODIC: organic molybdenum), it can hold an oil film under severe conditions. Though performance of the engine oil is in no way inferior to that of the racing engine oil, it also has oxidation resistance and low temperature stability ideal for street use. MODIC, organic molybdenum can quickly be penetrated into the metal friction surface where it makes a smooth metal surface by forming strong lubricating surface which in turn reduces the friction resistance and minimizes the loss of engine power as a result. Proven by bench-testing.

We believe that the oil line also plays a very important role. The MUGEN oil filter is exclusively developed for naturally aspirated engines and has “Y” shape cross section rather than a round cross section of the ordinarily fiber filter material. By adopting the “Y” shape, we were able to succeed in reducing the sludge reentering into the system with the sludge efficiently stuck on to the filtering fibers. At the same time, pressure loss is reduced by 10% and significantly increases the high temperature resistance capability.

TODA Exhaust Manifold for the 2006+ Honda Civic Si (FD2)

TODA competition exhaust manifold is developed based on data acquired from competition and continual engine dyno bench testing. It is designed to extract every bit of horsepower from a modified normally aspirated engine with attention paid to improving power all over the powerband.

Originally designed for the Japanese spec Civic Type-R (FD2) chassis. Primary Runners Secondary Runners Middle Section Collector 45mm 50mm 55mm~60mm 60mm

• For Competition Use Only. Factory Catalyst cannot be used.
• Compatible with US 4 door Civic SI (FA5 Chassis) under the condition both exhaust manifold and TODA exhaust systems (18000-FD2-00J) are used together.
• OEM O2 Sensor harness extension included.

Attention Competition Use Only: Vehicle modified by the use of competion parts may not meet the legal requirement for use on public roads.

TODA Exhaust System 2006+ Honda Civic Si 4 Door (FD2)

TODA Racing USA has concluded our test of the exhaust manifold and exhaust system orignally designed for the new Honda Civic Type-R (FD2) chassis. American spec Civic SI features a shorter catalyst compare to the Japanese Civic Type-R, which is un-heard of since any Honda enthusiasts that owned a B-series from 1990~2000 would know it was the opposite. Some of the significant difference in chassis/exhaust hanger designs are listed below. Since the factory catalyst in longer on the Japanese spec FD2 Type-R, which means the B-pipe after the catalyst is significantly shorter. Consumers would have to purchase both the exhaust manifold and exhaust system together if they intend on using TODA exhaust on their American spec Civic SI.
