Which means that when it comes to fitting a NSX with performance exhaust it needs to be a top quality item befitting of the Honda supercar’s legend – which is where Japanese tuning house TODA Racing comes in.

It’s just launched a new range of ‘High Power’ exhausts for both the 3.0-litre (C30A, 270bhp,) and 3.2-litre (C32B, 290bhp) variants of the Honda NSX.

Featuring an innovative ‘X-pipe’ between the two silencer boxes to minimise back pressure and maximise the aural experience from the NSX’s high revving V6 engine, the TODA ‘High Power’ exhaust features 60mm diameter internal tubing and slash cut round tailpipes boasting a smart titanium blue finish.

Surely these TODA exhausts are perfect for any discerning Honda NSX owner and they are available now from TODA Europe, priced at £2025.00 excluding taxes.

Designed to let Honda S2000′s  owners enjoy the full vocal delights of the amazing F20C engine, the new Super Sound Master has been cleverly designed to minimise resonance and drone, making it perfect for everyday use.

The HKS Honda S2000 Super Sound Master will be released later in 2012 and pre-orders are being taken now at principal HKS distributor Torque Developments plc.

Please email sales@tdi-plc.com to express your interest and place an order desposit.

As with the factory exhaust manifold, the new HKS Honda S2000 exhaust manifold is a 4-2-1 design, but the key difference is that the secondary pipes on the new HKS manifold are twisted to enable them to be longer, which boosts low and mid-range torque.

HKS also reports that the new Honda S2000 ‘twisted’ exhaust manifold also reduces detonation, enabling users to run a wider spread of ignition advance to boost power even further. Combine this with a top quality stainless steel construction that’s been optimised to maximise flow and reduce back pressure, the new HKS ‘Twisted’ manifold is set to be  a must have for Honda S2000 owners!

Pre-orders for the HKS Honda S2000 ‘Twisted’ exhaust manifold are being taken now, so to express your interest please email Torque Developments using sales@tdi-plc.com

Firstly a great upgrade package for Honda S2000 owners – a GT Supercharger kit.

Called the AP350SC-II Concept, the HKS package is specifically designed to increase the power output of the Honda S2000′s incredible F20C engine. HKS’s engineers specified the use of GTS7040 blower that ideally compliments the high revving 2.0-litre VTEC motor.

The end result is a fantastically responsive, torquey and powerful Honda S2000 that delivers approximately 350PS (345bhp) and is thoroughly engineered to the standards you would expect from HKS.

Pre-orders are now being taken for the HKS AP350SC-II Concept Honda S2000 supercharger kit, so if you want supercar performance from your S2000, please contact us using sales@tdi-plc.com for more details!

Having reduced the exhaust back pressure in part 2 of this blog, we turned our attention to minimising the intake restriction that creates a depression in the intake flow path which reduces engine performance.

Nick liked the look of the MUGEN high performance air box, and duly instructed us to install one.

As you would expect from MUGEN, the quality of the kit is exemplary and the fitment is perfect, taking approximately 1 hour to install.

Below you can see the MUGEN high performance air box kit installed on the CR-Z

Here’s the dyno chart for the standard air box and MUGEN air box, which shows a healthy improvement throughout the speed range.

When attempting to increase theVolumetric Efficiency (VE) of an engine, it’s important to reduce air flow losses in the paths to and from the engine.

The standard exhaust system is quite restrictive so it’s important to minimise (or preferably eliminate!) the back pressure within it.

Being particularly concerned about quality and efficacy, Nick chose a MUGEN exhaust system for Projekt HYCAEI.

Manufactured from high grade polished stainless steel, the MUGEN exhaust is probably the best quality system on the market!

The well established relationship between Honda and MUGEN ensures that the fitment is absolutely perfect as you may expect!

Below is a view of the MUGEN exhaust system as seen from the cat back.
