Here is a inside peek on building the manifold. Each manifold is hand built and the flanges are first cut on a water jet then the flange CNC ported. Collector and tubes are all hand cut then assembled in a jig and welded.
Talked to @rabtech last night. Can't wait for him to post up his video. He sounded soo happy with the kit and it's power delivery to propel him past 120+
He's like a kid in a candy store! A Turbo Candy Store that is!
