4.0TFSI Drop in exhaust manifold with turbine housing. This is a direct drop in replacement for the extremely restrictive factory exhaust manifold. 

These alleviate the cylinder 5 missfire issue by reducing EMAP caused by the extremely restrictive factory manifolds.

Horsepower increases of 50+ horsepower depending on setup. With larger turbos expect significantly more.

These uncork the main performance bottleneck of the 4.0TFSI engine by allowing the engine to exhale properly making the engine significantly more efficient because it doesn't have to work as hard to pump exhaust out of the engine. Not only will you have the exhaust flow to make more power, you will make that power more efficiently reducing strain on the engine by reducing backpressure.

Compatible with Factory Downpipe

These are an essential upgrade for anyone looking to make real power on the 4.0TFSI engine. 

These manifold turbine assemblies are sized to fit all drop in turbos, including S7, RS7, +4, TS1, etc.

They are available for larger turbine turbos as well in the drop down menu, including Xona, TS2* and TS2+*.
