Here are some sneak peak pics of our soon to be released PTUNING 4-1 Race Header. It is modeled after our 4-1 prototype header with a few changes. Per our usual goal of achieving the highest possible output with best overall powerband, we'll only be producing an equal length version of this 4-1 race header. Pricing will be competitive with the other premium quality headers on the market.
Some of the key design features that we're carrying over from our prototype.
- 4-1 double-slip race style merge collector (negates need for flex bellows, etc) with either a bolt-together or spring loaded interference fit (TBD).
- Rotational firing order for optimum cylinder scavenging.
- Shortest possible secondary pipe length to our turbo overpipe inlet for awesome transient response with our turbo set-up.
- Will fit with the factory front metal heatshield without modifications or spacers.
- T304 American-made stainless steel one-piece mandrel bent primary runners for the best look, flow, weight, and reliability.
- Unlike turbo headers, our header will not need to support the weight of a turbo and downpipe so the header should live a fairly happy life.
- T304 SS PTUNING-Spec CNC machined head flanges (2-3x the cost of mild steel CNC or laser cut flanges) meaning they will never rust.
- Fully polished and color tig welded connections.
- Will be manufactured right here in the USA.
- Toan
