Performance Boost: No remap is necessary, but adding a Booster Plug improves throttle response. For additional power gains, consider a race ECU map or mapped PCV.

Important Note: All CS Racing Full exhausts feature the removal of the catalytic converter. Some slip-on models may keep both or remove the main catalytic converter while retaining the high-flow cat in the headers. As a result, these exhausts do not comply with European regulations and may not meet street legal requirements in certain countries.
