Wagner Tuning Cast Evolution Exhaust Manifolds For B5 S4/RS4

This set of Wagner Tuning Cast Evolution Exhaust Manifolds for the B5 generation Audi S4/RS4 is a high-performance redesign of the OEM exhaust manifolds. This redesign eliminates the "log" style header design that reduced the exhaust gas-flow to a power-robbing bottleneck. Wagner Tuning's engineers have extensively reworked the OEM design to remove the restrictions altogether in a 3-into-1 merged collector design, allowing exhaust gases to travel unrestricted from the engine to the turbochargers.

The enhanced design of these exhaust manifolds gives your S4 or RS4 the added benefits of increased throttle response, faster turbo-spool up and improves top end performance allowing for an overall higher power output than without the manifolds.

Manufactured using a style called Investment Casting (Lost Wax), Wagner Tuning is able to achieve a very finely detailed structure in their casting, and this is the same method used by VAG to produce their OEM TFSI manifolds and turbocharger exhaust housings.

Note: The Driver's Side Downpipe requires some adjustment for fitment or Wagner can supply their own downpipe to suit.
