Description

The Solo Performance Mach-X3 is a 3-inch dual cat-back exhaust kit engineered for the 2008-2009 V8 Pontiac G8, accommodating both Standard and Automatic transmissions. Constructed from T304 polished stainless steel, this system boasts mandrel-bent 3-inch piping for optimal flow, complemented by an X-Design muffler and tunable J-Pipes designed to eliminate cabin drone. The kit includes 3.5-inch dual outlet exhaust tips, featuring a staggered design with an inner bevel. This performance-oriented exhaust is recommended for enthusiasts with significant modifications such as a computer tune, intake, high-flow catalytic converters, or headers. For vehicles without these minimum upgrades, Solo Performance suggests their 2.5-inch systems. The Mach-X3 is designed to bolt directly to Solo High Flow Converters (sold separately) or stock converters. Installation is facilitated by the completely bolt-on design, requiring only regular tools. All necessary hardware is included, along with heavy-duty reinforced hangers. Please note that the 3.5-inch dual outlet exhaust tips require the G8 GXP rear valence or diffuser for proper fitment; this component can be sourced from a local dealer if not already equipped.
