Allows for faster spool, higher boost targets, and lower EGTs
Adds deeper, more aggressive exhaust tone
Available in 76mm stainless steel or V-band for custom setups
Note: Catless may trigger CEL unless mapped out; 200-cell high-flow cat is a street-legal alternative in some regions.
2. Cold Air Intake / High-Flow Panel Filter
Increases airflow to the turbo
Enhances turbo noise and improves throttle response
Helps reduce intake air temperatures under load
Recommended brands: Revo, ITG, RamAir, Forge, APR, CTS Turbo
3. Stage 2 ECU Tune
ECU recalibrated for added airflow and reduced restriction
Boost targets increased to take advantage of downpipe and intake
Optional features:
Launch control
Overrun pops/bangs
Multi-fuel maps (95, 98, E30)
Rev limiter adjustments
Speed limiter delete
Tuned via OBD port or bench flash depending on year/model.
4. Optional: Upgraded Intercooler
Strongly recommended for hotter climates or spirited driving
Keeps intake temps low and consistent during pulls
Prevents heat soak and power loss
Brands: Wagner, Airtec, Forge, Revo, Pro Alloy
