Invidia HS22SW4JPC High Flow Catted J-Pipe Downpipe

The Invidia HS22SW4JPC is a high-performance catted J-pipe designed to replace the restrictive factory downpipe that connects directly after the turbocharger. This primary catted downpipe features a 4-inch diameter stainless steel construction with smooth mandrel bends that allow the turbocharger to expel exhaust gases with significantly less restriction and turbulence, resulting in substantial horsepower and torque gains with reduced turbo lag.

Key Features:

• Laser-cut cast steel and stainless steel flanges for durability and leak-free reliability at high temperatures
• High-flow catalytic converter for emissions compliance with minimal impact on exhaust flow
• 4-inch mandrel-bent SUS304 stainless steel piping for maximum flow and reduced backpressure
• Retains factory O2 sensor locations for compatibility with stock systems
• CNC-machined flanges and precision engineering for exact fitment
• One-piece design that replaces the restrictive stock catalytic converter section

What's Included:

• Invidia Primary Catted J-Pipe
• Turbo to Cat Gasket
• Cat to Intermediate Pipe Gasket and Hardware
• Heat Shield and Clamps

This exhaust component is engineered specifically for the 2022-2025 Subaru WRX and represents one of the most effective exhaust upgrades for turbocharged vehicles. The high-flow catalytic converter maintains street legality while delivering performance gains. Backed by Invidia's 1-year warranty against defects in materials and workmanship.
