SS Cat Delete Test Pipes

The Kinetix SS Cat Delete Test Pipes are engineered for the 2003-2007 Infiniti G35 Coupe and 2003-2006 Infiniti G35 Sedan, specifically for the VQ35DE engine. These pipes completely remove the factory catalytic converters, replacing them with a straight-through design to maximize exhaust flow. This modification is noted to provide 4-8HP gains on naturally aspirated G35 models and is considered essential for forced induction applications requiring maximum flow. Constructed entirely of stainless steel, the test pipes feature robust 3/8" flanges, TIG welding, and seamless mandrel bends for durability and optimal performance. The 2.25" tube diameter is designed to integrate seamlessly with aftermarket exhaust systems from brands like Borla, Injen, and Nismo. They retain the factory oxygen sensor mount, preventing a check engine light illumination. Additionally, these pipes utilize all factory mounting points, requiring no vehicle modification and are compatible with both aftermarket and factory headers and exhaust systems. Please note that these test pipes replace factory converters with straight pipes, rendering them for off-road use only and will not pass SMOG inspections.
