Key Features & Technical Highlights

Exhaust Manifold (316 Stainless Steel)

• CNC-machined one-piece 6-port flange.

• Constructed from 42mm OD / 36mm ID and 48mm OD / 42mm ID 316 stainless tubing (3 mm wall).

• Two runner sizing options provide flexibility:

  • Small ID → faster spool and response.

  • Large ID → higher peak horsepower.

• Equal-length manifold design ensures balanced flow and improved turbo efficiency.

• Welded with Fronius TIG equipment, using dual-sided argon shielding for maximum strength and reliability.

• Verified via ANSYS fluid dynamics testing for optimized gas flow and durability.

Turbo Compatibility

• 42MM Version supports all Precision Turbo T4 sized(6670/6870/7275/7675) turbochargers.

• 48mm version is compatible with Precision Turbo 6870, 7275, 7675, 7480 Sportsman, 8085 Sportsman, and 8385 Sportsman models via a special manifold adaptor.

Exhaust Sealing & Hardware

• Solid copper manifold gasket replaces OEM MLS for superior sealing.

• Upgraded reinforced V-band clamps for durability under extreme pressure and heat.

Downpipe (304 Stainless Steel)

• 4-inch OD, 2 mm wall stainless steel, dual-section A/B design for easier install.

• Fully welded inside and out, with dual-sided argon shielding.

• Compatible with OEM and aftermarket mid-pipes.

• Additional O2 bung for wideband sensors, with OEM O2 sensor provisions included.

Wastegate & Boost Control

• Dual Precision Turbo 46mm dual-port wastegates (LHD version).

• Choice option of internal dump and external dump exhaust routing(Screamer pipe ).

Oil & Water Lines
