Mazda 13B T4 Exhaust Manifold

Regular price $1,120.00 USD
Regular price Sale price $1,120.00 USD

Introducing our new 13B T4 Split pulse manifold for FD RX7.


This unique manifold has runner separation all the way to just before the wastegate valve face.


This has been a VERY complex manufacturing hurdle we have finally overcome.
By running a single wastegate you can also cut down on cost as well as an easier setup to thermal manage.


This manifold was 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, though as you can see we have provided a cut line if you wish to run a 60mm for any reason.
