aFe POWER Twisted Steel Y-Pipe — Part #48-48026
Unlock better flow and real-world performance on your JL or JT with aFe’s Twisted Steel Y-Pipe. This direct bolt-on assembly replaces the restrictive factory Y-pipe between the catalytic converters and your stock (or aFe Mach FORCE Xp) exhaust, improving exhaust scavenging for stronger throttle response and dyno-proven gains.
Key Features
- Dyno-proven gains: up to +8 HP and +14 lb-ft of torque (results may vary).
- 409 stainless steel: dual 2.25″ inlets merging into a 2.5″ outlet, all mandrel-bent for smooth flow.
- Hand MIG-welded construction with factory-style flanges for durability and a leak-free seal.
- Direct bolt-on: installs to OE mounting points; no cutting or modifications required.
- Works with the factory exhaust or aFe’s Mach FORCE Xp systems.

Why Upgrade?

Install Notes
- Direct bolt-on to factory locations; typical install time ~1–3 hours.
- Professional installation recommended. Always check for leaks after installation.
