Artec: Mazda 13B T4 Exhaust Manifold
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.
Designed and tested in Australia, backed with a lifetime warranty.
