TODA Europe is pleased to confirm that a high performance TODA Racing stainless steel exhaust manifold is now available for the European FN2 version of the Honda Civic Type R.

Developed specifically using extensive dyno testing to suit the characteristics of the FN2’s K20Z3 engine, the TODA Racing exhaust manifold is produced from high quality, lightweight stainless steel and uses a 4-2-1 design to boost mid-range torque.

Key technical features of the TODA Racing Civic Type R FN2 exhaust manifold include:-

• Dyno developed 4-2-1 layout to optimise mid-range torque
• Dimensions Ø 45mm – Ø 50mm – Ø 55mm – taper – Ø 60mm
• Optimised high flow pipe joints and angles to maximise gasflow
• Service adaptor included for stock Honda A/F sensor  
• CNC machined manifold / cylinder head mating flange

Designed to run without the front catalyst, the TODA Racing FN2 exhaust manifold has been back to back dyno tested by Torque Developments International, where it proved to significantly boost mid-range torque and top end power.

Available now from TODA Europe, a division of TDi-Plc, the TODA Racing Civic Type R FN2 exhaust manifold is priced at £1105.00 – excluding VAT – click on the link here to purchase now:- http://www.tdi-plc.com/catalog/toda-racing-exhaust-manifold-p-16104.html

The TODA Racing Suzuki Swift Sport exhaust manifold is available now from TODA Europe priced at £865.00. Buy this product now at http://www.tdi-plc.com/catalog/toda-racing-exhaust-manifold-p-18651.html

The second new TODA Racing product release for the Suzuki Swift Sport is a high performance exhaust system, designed specifically to mate up with the TODA exhaust manifold, as detailed above.

Specifically designed with a low back pressure, low resonance format, the key technical features of the TODA Racing Suzuki Swift Sport exhaust system include:-

• Produced from light weight stainless steel for both durability and looks
• Made from Ø60mm mandrel bent stainless steel tubing
• High flow sports catalyst included as part of system
• Service adapter for A/F sensor included
• A/F sensor extension harness included (for rear A/F sensor of standard catalyst)
• Compatible with standard Suzuki rear exhaust muffler

• Lightweight stainless steel construction 
• CNC machined manifold / cylinder head flange 
• Equal length 4-2-1 design
• All pipe lengths, angles and diameters are dyno optimised
• 45mm diameter headers with 50mm diameter primaries
• High gas flow joints to ensure maximum performance
• 60mm collector pipe with Lambda probe fitting
• Compatible with standard Honda catalyst

Dyno testing has proven that compared to original Honda header (and in conjunction with a remapped ECU) the TODA ‘Torquie-Kun’ S2000 exhaust manifold adds up 20 bhp and 20 lb.ft of torque in the mid range, with a slight increase in peak power.

This makes the ‘Torquie-kun’ perfect for the European fast road and trackday market where torque and tractability are vitally important, as these factors help improve the overall driveability of the car.

Suitable for AP1 and AP2 versions of the Honda S2000 using the F20C and F22C engine, the new Torquie-Kun’ exhaust manifold is available now from TODA Europe (a division of TDi-plc) priced at £1169.13 including VAT @ 17.5%.

The standard exhaust manifold is very restrictive and is detrimental to performance, fuel economy and engine reliability.

The standard manifold has exceptionally small primary pipe diameters (probably to assist a fast warm up of the pre-catalytic converters), and the primary pipe lengths are too short (probably due to packaging concerns) for optimum torque. The manifold also includes pre-catalytic converters which are restrictive and known to fail internally.

The first stage of our development process was to accurately measure the camshaft timing so that we could run some calculations through our modelling programme to determine the ideal theoretical primary lengths and diameters, the secondary lengths and diameters, and the collector lengths and divergence angles.

Because of the packaging issues and design of the downpipe/main cat pipe, we could not implement the ideal secondary collector length so we chose to introduce pulse tuning loops in the desired location of a secondary collector. This proved to be an acceptable solution because it provided easy interchangeability with the standard manifold and gave us a good performance increase.

Dyno testing was carried out with various combinations of pipe lengths and pulse tuning loop locations, and the final design was signed off.

The improvements in power and torque makes it ideal for all fast road applications, and for any intended race use where uprated engine internals are deployed.

Benchmark testing was carried out competitive products, and we were pleased to note that the Katana exhaust manifold outperformed the other manifolds by a very significant degree.

We were not surprised by this as the Katana manifold was (and still is) the only high performance exhaust manifold for the Lexus iS200 which has had some science applied to it’s development.

Other concerns were raised about the other manifold such as incorrect pipe dimensions, quality of manufacture, slip joints instead of being a one piece construction, the collector pipes being squashed together instead of having the correct divergence angle.

Here you can see the difference between the standard manifold and the Katana exhaust manifold for Lexus iS200.

Here you can see the difference in collector design between the Katana manifold and that of a competitor. Note the poor design of the competitor.

Here you can see the difference between the Katana and the competitors manifold. Note the sharp change in in primary pipe direction which slows gas speed.

The Katana manifold can also be heat wrapped for thermal insulation
