Show original supplier description
The BBK High Flow Catted X-Pipe is engineered to enhance the performance of your 2005-2010 Ford Mustang GT. It is constructed from 2-3/4" mandrel-bent steel tubing and includes high-flow catalytic converters to ensure maximum exhaust flow. This x-pipe is a crucial part of completing a long tube header installation and is designed exclusively for use with BBK Long Tube Headers, specifically part numbers 1641 and 16410. The system features rear oxygen sensor bungs located in the factory position for a straightforward installation. It is important to note that front O2 wire harness extensions (Part #1676) are recommended for installation and are sold separately. Emissions information indicates that this part is NOT CARB Approved and cannot be installed on emission-controlled vehicles in California. It cannot be shipped to any California resident or address. BBK Performance warrants its parts against defects in materials and craftsmanship for one year from the original purchase date, provided they are installed and used according to guidelines and not for racing.
