Catalyst information:
Replacing the restrictive OEM catalyst not only enhances power but also improves sound. By upgrading to our catted downpipes increasing flow while still effectively catalyzing exhaust gases. By allowing for better exhaust gas scavenging and reducing backpressure, these modifications can increase power output, improve turbo spool, and offer a more aggressive exhaust note.
Unlike the ineffective catalytic converters found in generally cheaper aftermarket options ours has been designed for superior performance.

Our high-performance catalytic solution.
Featuring Euro 6 standard purification coatings, our catalytic converters have a higher density of precious metal coatings compared to OEM units on the same surface area. This results in superior exhaust gas conversion performance, allowing for more efficient purification when replacing with a more performance-oriented high-flow Downpipe without releasing harsh, toxic fumes. In terms of design, the catalytic converter employs a three-spiral metal carrier structure that enhances the carrier's shock resistance and durability. This ensures that the catalyst unit remains stable under the continuous impact of pressure waves and pulses from high-horsepower engines.

• Effective operating temperature: 480°F–1470°F
• Short-term tolerance temperature threshold: 1650°F–1830°F
• Long-term tolerance temperature threshold: ≤1560°F Exposure to temperatures above 1470°F for extended periods will shorten the catalyst's lifespan. Main precious metal components and applications: Platinum (Pt) Characteristics: High catalytic activity, heat-resistant, corrosion-resistant. Applications: Oxidizes CO and HC (hydrocarbons). Reduces NOx. Advantages: Stable performance in both oxygen-rich and oxygen-poor environments. Palladium (Pd) Function: HC oxidation: More efficient at oxidizing unburned hydrocarbons (HC) compared to platinum. Advantages: When combined with platinum or other precious metals, it offers better conversion efficiency for unburned hydrocarbons (HC). Rhodium (Rh) Characteristics: Exceptional NOx reduction ability.

9m floating rear brake disc replacement set 
Not suitable as PCCB conversion 

Disc size : 380 x 30mm
Direct replacement for steel assemblies with 380mm rear discs

Hat and Floating disc assembly kit with slotted road brake discs (Left and Right)
Two-piece floating slotted  front iron disc upgrade (including centre lock wheels)

• Rotors come with 48 cooling vanes for optimal cooling.
• Assemblies made of CM-250  formulated high carbon alloy cast iron, it allows for high-temperature strength and durability.
• Hat assemblies are CNC machined from 7075 T6 material then hard anodised.
• Rotor rings are heat treated to release stress in the rotor to avoid deformation and vibration.

High brake coefficient of friction 0.55
With higher stopping power and maximum effective operating temperature, the 9M compound is ideal for advanced high speed track events, competitions and heavier cars that require maximum braking performance.

• Good modulation and release characteristics 
• Excellent pad and rotor life
• High fade resistance compound, with solid pedal feel throughout the effective temperature range 
• Not compatible with PCCB
