2004 996 C4S Stage II: HRE R40 Wheels & Tubi Exhaust, V-Flow & EVOMSit

This very clean '04 C4S came in recently for a couple changes including the EVOMS V-flow intake for a bit more power and engine sound, Italy's superb Tubi exhaust and EVOMSit software for more kick and sharpened throttle response.

The plan was to take weight off the wheels, check out our article showing the weight savings using the same wheels, featured on our 996 GT3.

And here she is ready to head home:
