Tubular Exhaust Manifold | Mazdaspeed 3/6

Take your Mazdaspeed to the next level with our hand-built Tubular Exhaust Manifold, crafted from precision-cut Schedule 10 304 Stainless Steel with a 1.5" inner diameter for optimal flow. Designed to perform, it features a smooth-flowing cast collector and perfectly positioned wastegate flange to eliminate boost creep and prevent runner bottlenecks.

This is a stock location/stock flange manifold, meaning it is compatible with any turbo that utilized the factory manifold flange, inlcuding the OEM K04, BNR S1-6, CST4-6, as well as many garrett/ATP turbos. 

Choose between 38mm or 44mm Tial wastegate options. Every manifold includes a dump tube (can be routed under the car or modified for a hood dump) and an EWG block-off plate for internally gated setups. Custom hood dump designs available on request.

Not only does it perform—this is one of the best-sounding manifolds on the platform, delivering a deep, aggressive tone with a touch of rumble (sound may vary by exhaust setup).

Proven on high-horsepower builds with zero failures to date.
