A downpipe, the right calibration, and the car becomes a different animal.
Stage 2 pairs the core hardware your platform wants with a calibration built for it — sold as a kit so it's one decision, one price, and the parts and tune are matched instead of guessed. We build the tune to your exact parts, not a generic Stage 2 map.
Outcome ranges are chassis-specific. Tell us your car and we’ll show your platform’s Stage 2 band — drawn from what these engines actually make on this stage.
— whp on this chassis (tuned + E-mix, full ladder published). Read as a range, not a hero number.
Catless downpipe + chassis-specific Core · matched Stage 2 calibration · log review + revisions · documentation.
Repeatable numbers, room to grow. Stage 2 opens the engine's charge path so the calibration can use it — and the kit makes sure the parts and the tune ship aligned. You buy a build path, not a guess.
What's in the Stage 2 Kit.
Catless downpipe
The Stage 2 gateway part. Removes the post-turbo restriction. Sold inside the matched Stage 2 Kit so the tune is built for it.
Charge pipe
Replaces the failure-prone factory piece. Chassis-specific in the Stage 2 Kit.
Front-mount intercooler / chargecooler
Holds intake temps through repeated pulls in real ambient — not just the first run.
Matched Stage 2 calibration
Built to your exact parts, not a generic Stage 2 map. The kit + the tune ship together.
The parts and the tune, designed together.
Kit + tune
One decision, one price. Parts and calibration designed to work together.
Less than the sum of parts
Kit priced below the sum of its components — the savings is in the math, not a banner.
Every revision
Written change notes per chassis. You know what's on the car.
