This E63 AMG came into the shop looking for one thing more power. The owner chose the full RENNtech R1 Package along with RENNtech catted downpipes to wake up the M177 twin turbo V8. We also installed the RENNtech Blow Off Valve Upgrade, Exhaust Valve Module, and Hand Held Tuner to complete the package.

The result? Around 800 horsepower with incredible throttle response, aggressive sound, and factory-like drivability. Before adding performance upgrades, we always make sure the engine is healthy. A solid foundation is the key to reliable power.

Would you keep your E63 AMG stock, or build it to 800 horsepower?

​Materials: Inconel for the manifolds, and titanium from the catalysts to the tips (with ceramic coating). ​Piping Shape: To fit the tight G-Class underbody space, the pipes can be flattened into an oval shape while maintaining a 3.5-inch cross-sectional area. ​Catalysts & Flow: A straight-through ("non-stop") design is entirely feasible to minimize backpressure and support the 1,000-hp level.
