Frequently Asked Questions

Does matching the vehicle model guarantee ISR fitment?
No. Confirm the exact year, engine, transmission, drivetrain, body style, factory configuration, connection points, and manufacturer part number.

Do ISR exhaust systems require tuning?
Most cat-back and axle-back systems do not normally require tuning, but headers, catalyst changes, forced-induction parts, engine swaps, and sensor changes may require calibration and additional components.

Is professional installation recommended for ISR parts?
Yes for work involving vehicle support, brakes, steering, suspension geometry, drivetrain components, fluids, wiring, exhaust alignment, or fabrication.
