This setup was developed both as a replacement for cracked OEM exhaust manifolds and as a strong, primary foundation for tuning and turbo upgrade projects.

About the kit

• Cast exhaust manifolds made from AISI 304 stainless steel (5 mm wall thickness)

• Universal fit — works on both left and right banks

• Each manifold features two symmetrical independent V-band 1.75" outlet ports:

  • Each v-band outlet is sized to support approximately 300 hp per bank, providing sufficient flow capacity for high-performance applications.

  • Flow capacity is based on internal cross-sectional area and real-world turbocharger operating conditions.

  • The second outlet can be used for:

    • EGR piping (adapter sold separately)

    • External wastegate for exhaust pressure relief when operating turbocharger near turbine flow limits

This dual-port configuration allows maximum flexibility in system design while maintaining balanced exhaust flow.
 

Possible Installation Options (components not included)

• 90° elbow to OEM turbo (Transfer Pipes, available separately)

• Pipe to relocated or upgraded turbo

• Quad-turbo configurations

• EGR piping (adapter required, sold separately)

• External pressure relief (e.g. when using OEM turbo with larger compressor)

Once installed, the cast manifolds are built to last.
V-BAND connections allow upgrades or changes to top-side components without engine removal.

(Pipes, elbows, and flex joints are not included in the kit.)

Can be used as a base solution (requires 90° elbow + bellow from the supplied V-band flange to the stock turbocharger) for both Touareg and Phaeton V10 TDI exhaust manifold replacement, left and right
(OEM: 07Z 253 033 / 07Z 253 034, incl. revisions).

What’s included

• 30 m basalt thermal wrap (50 mm width)

• Stainless-steel wrap clamps

• Set of V-BAND 1.75" flanges with quick-release clamps
  (one per outlet, CNC-machined) including outlets

• V-BAND plug disk with NPT 1/8 sensor port

• NPT 1/8 plugs (if sensors are not used)

• 2 pairs of JIC 1/4 → NPT 1/8 adapters (male/female), tested at 6+ bar

• Steel template for correct manifold positioning on cylinder head
  (thermal expansion compensation)

• 12 mm steel drilling jig for alignment pins

• Centering pins included

Advantages

• No need to source or machine custom flanges

• Everything pre-checked and designed for fast installation

• Durable and flexible solution for both OEM replacement and performance builds
