ARTEC PERFORMANCE Mazda 13B T4 Exhaust Manifold


All Artec manifolds are designed using CFD software to ensure they maximize flow, which, in combination with their revolutionary cast stainless steel construction, ensures that not only do you get he most power, but also the most reliability.

This unique manifold has runner separation all the way to just before the single wastegate valve face. Single  wastegate? Yes, single. This has the significant advantage of cutting costs in additional parts and also reduces the amount of thermal management required.

This manifold is designed to accommodate the @garrettmotion G40 turbo, which will leave you space for other smaller units.

The 13B manifold also features wastegate machining to suit a Gen 5 @turbosmarthq 50mm wastegate. Should you want to go bigger, Artec has even provided a cut line if you wish to run a 60mm for any reason.
