Will this exhaust fit my Lexus ISF?
Yes, this valved catback system is designed specifically for the Lexus ISF 3.8. Fitment is bolt-on to OEM mounting points. If you're unsure, contact Project Styling to confirm your vehicle specification.

Can I control when the valves open?

Is professional installation necessary?
Whilst mechanically inclined owners may attempt installation, professional fitting is recommended to ensure proper alignment, secure sealing of all joints, and correct valve operation. Project Styling offers fitting services in Southend-on-Sea.
