 Catalyst information :
 
Replacing the restrictive OEM catalyst not only enhances power but also improves sound.By upgrading 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.
