Evolution Racewerks Evolution Racewerks Sports Series Metallic High Flow Catted Downpipe - Toyota A90/91 GR Supra B58 3.0L TO-EXH001CAT

Evolution Racewerks Sports Series Metallic High Flow Catted Downpipe - Toyota A90/91 GR Supra B58 3.0L

Restrictions in the exhaust system rob horsepower and torque, especially on turbocharged cars. Thus, removing exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. Evolution Racewerks' Sports Series 4.5" High Flow Catted Downpipe is the perfect solution to improve your BMW's power capabilities! Featuring a high-flow 200-cell metallic catalytic converter and 4.5"/4" mandrel-bent piping, this downpipe is designed to provide the highest exhaust flow possible without triggering a Check Engine Light. Additionally, this downpipe can be used with your stock or aftermarket* exhaust systems, eliminating the need to have a muffler shop adapt this downpipe to your existing exhaust system.

Evolution Racewerks Sports Series Metallic High Flow Catted Downpipe - Toyota A90/91 GR Supra B58 3.0L
$945.00

Restrictions in the exhaust system rob horsepower and torque, especially on turbocharged cars. Thus, removing exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction.

Evolution Racewerks' Sports Series 4.5" High Flow Catted Downpipe is the perfect solution to improve your BMW's power capabilities! Featuring a high-flow 200-cell metallic catalytic converter and 4.5"/4" mandrel-bent piping, this downpipe is designed to provide the highest exhaust flow possible without triggering a Check Engine Light. Additionally, this downpipe can be used with your stock or aftermarket* exhaust systems, eliminating the need to have a muffler shop adapt this downpipe to your existing exhaust system.

Finish Options:

  • Brushed Finish
  • Polished Finish
  • Black Ceramic Thermal Coating
    • The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out.  This keeps underhood temperatures lower and less heat absortion by nearby parts/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure.  The ceramic coating also adds additonal corrosion resistance. This thermal coating can resist up to 2000 degrees Fahrenheit and is available in BLACK ONLY.

CAUTION: This product is intended for OFF ROAD COMPETITION USE ONLY. Not legal for use on pollution controlled vehicles upon public road/highways. THIS PRODUCT IS FOR SALE FOR ALL 49 STATES EXCLUDING CALIFORNIA.

*Note: For aftermarket exhaust systems designed to work with the factory downpipe. Exhaust systems intended to be used with specific aftermarket downpipes may require modification for proper fitment.

Not for sale or use in the state of California on any pollution-controlled vehicle as per the California Air Resources Board.
