aFe Power Twisted Steel 3-Inch to 4-Inch 304 Stainless Steel X-Pipe with High-Flow Catalytic Converters (48-34129-1YC) - 2014-2019 Chevrolet Corvette C7 / 2015-2019 Z06
Upgrade the exhaust system on your 2014-2019 Chevrolet Corvette C7 or 2015-2019 Corvette Z06 with the aFe Power Twisted Steel X-Pipe. Constructed from 3-inch to 4-inch mandrel-bent 304 stainless steel tubing, this system features dual high-flow catalytic converters, an integrated mitered merge X-pipe, and a crossover balance tube designed to improve exhaust flow, reduce drone, and enhance exhaust sound.
Engineered with optimized tubing lengths and durable MIG-welded construction, the Twisted Steel X-Pipe weighs approximately 3 pounds less than the factory system. Its direct bolt-on design utilizes factory-style mounting points for installation without cutting or permanent modifications.
3-Inch to 4-Inch 304 Stainless Steel Construction
The Twisted Steel X-Pipe is manufactured from 3-inch to 4-inch mandrel-bent 304 stainless steel tubing with a brushed finish. Optimized tubing lengths help improve exhaust flow and performance, while 3/8-inch thick 304 stainless steel head flanges provide a durable connection.
The system features 100% MIG-welded construction for strength and durability and is approximately 3 pounds lighter than the factory exhaust components it replaces.
Dual High-Flow Catalytic Converters
This system incorporates dual high-flow catalytic converters designed to support improved exhaust flow. The converters are integrated into the X-pipe assembly for the specified C7 Corvette applications.
Integrated Mitered Merge X-Pipe
An integrated mitered merge X-pipe balances and evenly distributes exhaust pulses traveling through the system. This design helps maximize exhaust scavenging while minimizing unwanted exhaust drone.
Integrated Crossover Balance Tube
The crossover balance tube further equalizes and distributes exhaust pulses between the exhaust paths. This configuration helps reduce drone and improve the overall exhaust sound.
Direct Bolt-On Installation
Designed to utilize factory-style flanges and hangers, the Twisted Steel X-Pipe installs as a direct bolt-on replacement without cutting or permanent vehicle modifications.
aFe Power exhaust systems are engineered and manufactured at the company's facility in Corona, California.
