Stage 2 Kit — B48
Stage 2 Kit — B48: the core hardware and the calibration that uses it, matched as one build.
Stage 2 is the exhaust-and-charge-path package the B48 wants, paired with a calibration written for that exact hardware. We sell it as one decision so the parts and the tune ship matched rather than guessed — a downpipe frees the exhaust, an upgraded charge pipe and front-mount intercooler keep boost moving and intake temperatures down, and the calibration is the part that turns all of it into repeatable power.
What's in the set
- Evolution Racewerks Competition downpipe — B48 (F-Series + G-Series), opening up the exhaust path.
- Aluminum Charge Pipe — B48, replacing the OEM plastic pipe.
- VRSF front-mount intercooler, sized for sustained heat rejection over the stock core.
- The matched custom BM3 calibration for your chassis.
What to expect
Community-observed Stage 2 gains on the B48 land well above stock when run on supporting fuel. We state figures as ranges rather than a single headline number because they depend on fuel, ambient, and the specific car; the chassis tune page lists the published ceiling for your platform.
The saving
8% under buying the components and tune separately — the kit price reflects the matched build, not a discount gimmick. The savings indicator on this page shows the current figure.
One cart line; components ship as their individual SKUs.
Ships from Boca Raton, FL. Hardware components within 3-5 business days; tune license emailed after post-install datalogs.
Build a custom bundle.
Toggle on what's already on your car. We'll subtract those and price the rest as a bundle. Bundles need at least two parts left — if you've got nearly everything, the full kit above is already the right call.
Why one SKU, not a parts list.
Every kit is priced 8% under the same components bought separately — the standing rule on every kit we sell, with the exact figure for this one on the vs à la carte line in the panel above. The components are matched as a set, and the kit price applies only when they are purchased as one SKU.
We schedule installs at the shop for kit buyers in Florida. Out-of-state buyers can choose a Phantom-certified installer or DIY with our install instructions. The calibration is delivered remotely either way.
