Our Titanium system is an ultralight weight alternative for the driver who only wants the best. We have redesigned the rear box to keep weight to a minimum yet retained the infamous QS sound.

• Dyno tests show a 16bhp improvement, increased mid-range torque and noticeably improved throttle response.
• Accelerated gas-flow draws heat away more efficiently to reduce under-bonnet temperatures particularly important for a tuned engine.
• These 'Race' catalysts produce a crisper exhaust note which, coupled with the improved response, deliver some of the 'GT4' experience.
• Substantial weight reduction of 6 kilos over the OE parts.
• The original lambda sensors are retained in their correct positions for the proper operation of the OBD2 (on-board diagnostics) system.
• In certain applications an ECU re-tune may be required to avoid a CEL.
