Rush Plux - Hybrid Catalyst Downpipe

RushPlux HybridCat Downpipe  
We engineered the lowest 50cpsi high flow racing catalyst , high volume precious metal coating.  We precisely calculated the back pressure by measuring the exhaust flow to increase the torque.  By running factory O2 sensor and ECU setting, the air/fuel mixture is precisely calculated for the ultimate ignition efficiency.  Increased engine performance and exhaust noise.  At the same, the efficiency and emission remain factory standard.

Applicable Car Types: Supercars. Race Cars

We have a first-class welder, due to leakage caused by engine damage, the original specifications development, precision pin,  direct installation, no need to modify

Why do we need high flow Downpipe
Higher and faster flow rate 
Reduce the turbine exhaust temperature and protect turbine life​
​More accurate oil supply
Reduce turbo lag
Reduced exhaust back pressure 
Increase the exhaust sound waves 
No Check Engine Light and comply with environmental regulations 

Note: 1-Year Product Warranty only apply if the vehicle is equipped with RP or factory exhaust part.  Please do not install any product not been certified by RP.
