Frequently Asked Questions
SPDZ1 Primary Cat Delete Test Pipe Kit
Part Number: (SZY-052-CATLESS)
The factory primary catalytic converters on the 2004-2008 Acura TL are one of the largest restrictions in the exhaust system. The SPDZ1 Primary Cat Delete Kit replaces the restrictive OEM catalytic converters with smooth-flowing mandrel-bent stainless steel test pipes, improving exhaust flow, throttle response, and overall engine performance.
Manufactured from premium 304 stainless steel with precision-cast flanges and TIG-welded construction, these test pipes are engineered for excellent fitment and long-term durability. They are designed as a direct bolt-on replacement and include the installation hardware needed to complete the job. Similar products in this category feature 304 stainless steel, 2.25-inch piping, TIG welds, O₂ sensor bungs, and included adapters/hardware.
