Applications: Fits EG, DC2, and EK chassis with Prayoonto and Hasport Lean Mount kits
In the Fall of 2012, Prayoonto Racing introduced their Gangsta Lean engine mount kit to a very surprised crowd at an East Coast drag race event. By leaning the Honda K-Series engine forward several degrees on their street All Motor EG Civic, the team found a couple significant advantages. The leaned position straightened out the ITB's on the intake side, allowing installation of a large air box with a perfectly placed, front bumper opening. It also made some extra space available at the rear of the engine bay, opening the door for a much larger hood exit header. Fast forward a few years, and Lean Mount kits are considered a must have on any competitive all motor drag race car. Also on that must have list is a compatible free flowing race header.The K-Tuned Lean Header was developed after reviewing some of the other designs and making a few revisions. This header was built to provide all out top end power, using a proven performance header recipe. Starting at the head flange, equal length stepped primary tubing is used to get the exhaust flowing quickly into the massive 48mm primaries, which move up to 50mm, then to 54mm. To ensure a super smooth transition, the tubes meet up in a true 4-1 merge collector with a 65mm (2.5) exit. A megaphone is added next, to release pressure and increase the speed of the exiting exhaust gases. A small reverse cone is placed at the very end to provide a tiny bit of wanted back pressure. Hiding the small reverse cone, a 90 degree 88mm (3.5) pipe turns upward and is made with a series of pie-cuts, to help make the tight radius turn for the hood exit possible. The K-Tuned Lean Header is precision tig welded and is constructed entirely of 304 stainless steel. It currently fits the EG, DC2, and EK chassis with Prayoonto and Hasport Lean Mount kits.
