Car makers must compromise the design and manufacture of their components for various reasons. The QuickSilver team removes these limitations to provide the Elise/Exige owner with an exhaust system to meet expectations. Designed for ‘Sports’ and Track Day Use for the driver who uses the car in an environment where the performance is fully exploited, yet
appreciating the throttle response, lighter weight and more volume throughout the revs.

• Unique crisp sound rising in proportion with rpm.
• Dyno tests show a 6 bhp improvement, more torque and better throttle response.
• Huge weight reduction from rear of car - To benefit all areas of performance!
• Great appearance. All polished with larger trims.
• Accelerated gas-flow draws heat away more eciently to reduce engine-bay temperatures.
• Aircraft grade 304 austenitic stainless tube & tips.
• No cutting the undertray.
• Tail-pipes emerge from the undertray and turn up to follow the curve of the rear panel.

Sound - Volume Measurement.

(MSA Test-2004)
 
Notes:
1/ The standard factory system’s volume increases to 94dB and, even though the tone changes, the volume remains constant.
2/ The QS system is designed to meet the standard MSA scrutineering test at 6125 rpm which is 75% of max rpm - taken 1m @ 45°.
3/ The volume of the QS Ti system continues to rise after the VVT operates at 6200 rpm.
4/ We recommend that detail attention is paid to the fixing of the undertray.

Weights of Cat-back systems
Lotus Standard 13.2kgs (~29.0lbs)
Lotus Stage 1 11.8kgs (~26.0lbs)
Lotus Stage 2 8.2kgs (~18.0lbs)
QS Stainless 6.8kgs (Saving ~ 6.4kgs - 14.0lbs)

This QuickSilver system uses the single large inlet and twin smaller outlet conguration to an advantage. By tailoring the natural venturi effect of this layout we can alter the speed of gases through the internal chamber to control the sound produced - optimum ow eciency that works with the car’s Toyota VVT engine.
