Description

The K-Tuned 8th Gen Civic SI Header was specifically designed to optimize the performance and power output of the K20Z3 engine that is found in all 2 and 4 door SI models. The header was developed using a proven 4-2-1 Tri-Y design that delivers power gains almost everywhere in the power band, not just the higher rpm range. Additional performance is accomplished by using large diameter piping to speed up the flow of exiting exhaust gases. We also use stepped piping and smooth transitions that minimize restriction. Fitment past the subframe and sway bar is perfect with extra clearance available for engine movement.

We start with 44mm primaries that smoothly step into 50mm secondaries and finish with a 64mm or 2.5” exit. Like all our headers, it is assembled using mandrel bent, 304 stainless steel tubing and is fully tig welded. We also use a slightly thicker gauge tubing that allows for better weld penetration and additional strength. The CNC cut 3/8" thick flanges are also double welded and then ported for optimum flow at entry and exit. This header directly replaces the OEM 2 piece design and eliminates the catalytic converter so we included a short 2.5" test-pipe with defouler for the secondary O2 sensor. Option for a cat coming in the near future.

    Design Services: Car Menu launched

    Wed, 18 May 2005

    Within almost every automotive design department throughout the world, their comes a time when a junior designer is dispatched to find a picture of some new model's tail lamp, the side view of a particular class leading competitor or examples of several new cars' colour and trim packages. Whilst looking at the competition is not necessarily a healthy way of finding ideas, it is often essential to demonstrate what is feasible, check in-house proposals are not too derivative, or show how advanced a design theme is relative to the same type of cars on the market. But even if the particular aspect of a car can be found, press packs and magazines typically show cars in the flattering light of an exotic location or being drifted around a corner on opposite lock; rarely are these images particularly useful.

    Aston Martin's Race plan

    Wed, 17 Oct 2007

    By Ben Pulman Motor Shows 17 October 2007 15:36 It’s only just over a week since Aston Martin was sold, but today it confirmed plans to race at Le Mans.The DBR9 will return to the famous La Sarthe circuit in June. Perhaps this was inevitable, since Aston’s new non-executive chairman is David Richards - the chairman of Prodrive, which develops the DBR9 and its FIA GT3-spec sister car, the DBRS9. The team will face a tough challenge, though, as the 24-hour Le Mans is the only race that Aston Martin Racing will compete in this year.
