6-1 to T4 1.5" Sch10 Merge Collector

Build your custom 6 cylinder high horsepower turbo manifold with precision using our 6-1 to T4 1.5″ Sch10 Merge Collector.

• Proudly Designed & Cut in the USA: Precision CNC cut and notched in house to guarantee tight tolerances and zero gap runner alignment right out of the box.

• Ready for Fabrication: Pre-cut and trimmed so you can jump straight into fitting, tacking, and TIG welding. Saving you hours of tedious manual grinding and miter prep.

• 6-1 Runner Configuration: Designed to join six 1.5" Sch10 runners into a single high efficiency merge point, ideal for inline-six and V6 custom manifold builds.

• 1.5" Schedule 10 Pipe Fitting: Machined specifically to fit 1.5" Sch10 weld elbows and straight pipe for maximum wall thickness and crack resistance.

• T4 Turbine Flange Match: Precision tapered 4" tall geometry transitions smoothly to match the standard T4 single-scroll turbine inlet opening (sold separately).

• Optimized Exhaust Velocity: Smooth 4" collector height ensures a gentle transition angle, reducing backpressure and maximizing pulse scavenging for faster turbo spool.

Take the Hassle Out of Custom Manifold Fabrication

Hand cutting and mitering a complex 6 into 1 merge collector is one of the most time consuming and challenging parts of building a custom turbo manifold. Our pre-cut collector eliminates the guesswork, providing laser accurate runner symmetry and clean internal junctions so you can focus on building a high-flowing, professional grade manifold.
