Built for high-performance K-Series turbo setups, this equal-length turbo manifold, downpipe, and dump tube combo is designed specifically for K-Swapped 1992-2000 Honda Civic and 1994-2001 Acura Integra chassis.

Constructed from extra-thick Schedule 40 stainless steel with precision TIG welding, the manifold is engineered for maximum durability, improved exhaust flow, and reliable high-boost performance. The true 4-1 merge collector is ported for better flow and faster turbo response, while the enlarged wastegate passage helps reduce boost creep and spikes.

Unlike most manifolds that use mild steel flanges, this setup features a massive 11mm stainless steel flange for superior strength, corrosion resistance, and long-term sealing performance. Each flange is resurfaced after fabrication to ensure a perfectly flat mating surface.
