T304 Stainless Steel • 2.75" Free-Flow

With a 2.75" free-flow design and stunning carbon fiber tips, this system delivers the brutal soundtrack and presence the G63 deserves.

ECU tuning works by modifying the software that controls engine parameters like fuel mixture, ignition timing, and boost pressure to optimize performance.
The process of installing a tune depends on the vehicle’s make and model. Some tunes are installed by connecting a tuning device to your car’s OBD-II port and uploading the tuned software, others may require ECU unlock.
Stage 1 is for vehicles with no modifications, stage 2 is for vehicles with bolt-on upgrades or downpipes installed.
We offer post-installation support, troubleshooting, and guidance on using your tuning software and hardware.
Choose tuning software that is compatible with your vehicle, has good reviews, and suits your performance goals (e.g., reliability vs. max power).
