What is a Test Pipe?

A test pipe (also called a decat pipe or straight pipe) replaces the factory catalytic converter with a straight section of pipe. The catalytic converter, while necessary for emissions compliance, creates significant exhaust restriction. Removing this restriction allows exhaust gases to flow more freely, reducing backpressure and allowing the turbocharger to spool more efficiently. The result is improved power output, faster turbo response, and a more aggressive exhaust sound.

3" Stainless Steel Construction:

The test pipe is constructed from stainless steel, providing excellent corrosion resistance and durability. The 3" diameter matches the Genesis Coupe's performance exhaust requirements, providing optimal flow without excessive velocity loss. Stainless steel withstands the high temperatures of the exhaust system and resists corrosion from moisture and road salt, ensuring long service life.

Improved Exhaust Flow and Power:

The straight-through design eliminates the flow restriction of the factory catalytic converter. The catalytic converter's honeycomb substrate creates significant backpressure that limits exhaust flow, especially at high RPM and boost levels. By replacing it with a straight 3" pipe, exhaust gases can exit the engine more freely, allowing the turbocharger to operate more efficiently and the engine to produce more power. Power gains are typically most noticeable at higher RPM and boost levels.

Check Engine Light (CEL) Note:

Removing the catalytic converter will typically trigger a check engine light (CEL) due to the downstream O2 sensor detecting the absence of the catalyst. This can be addressed with an O2 sensor spacer/simulator (sold separately) or by using an ECU tune that disables the rear O2 sensor monitoring. This is a normal and expected result of catalytic converter removal.
