Mazda 13B V-Band Exhaust Manifold

Here is our new 50-55mm V-Band 13B FD manifold design to run @turbosmarthq 50mm Wastegate.


This was designed to run turbo sizes from @garrettmotion GTX3076 through to a massive @xonarotor 76mm.


It uses our patented universal V-Band mounting system to allow mounting of a @precisionturbo 6466 or many other V-Band turbos up to your 13B.


This manifold is very unique in that it’s designed to run an open scroll turbine housing but it’s designed to remove the issues seen in 2 Rotor where the exhaust gas can be pushed back into the other rotor after the exhaust movement.


We have forced air to be traveling in the direction of the turbine wheel as well as splitting the wastegate ports and keeping them seperated all the way to the 50mm wastegate flange.

At ARTEC we have revolutionised the turbo manifold industry with our industry leading SUS347 stainless steel investment cast manifolds.

All of our manifolds are engineered and designed from the ground up, CFD simulated and, most importantly, tested in the real world to achieve maximum flow and heat dispersion. The cast stainless construction allows us to maximise flow and efficiency by having smooth merging angles and eliminating any restrictions from tight radius bends or runners.

The result is a truly optimised manifold with consistent performance, resistant to heat pooling and cracking, plus a beautiful smooth exterior finish.

Designed and tested in Australia, backed with a lifetime warranty.
