Install Difficulty: DIY Possible
Bolts to factory hangers and connects to OEM manifolds or headers with hand tools; typically installs in 60-90 minutes with a vehicle lift, longer on jack stands.

Product Overview

This catback is built from 304 stainless steel for long-term corrosion resistance on heavy-duty trucks. It uses an X-pipe muffler paired with dual S-tube mufflers to produce the signature Redline tone.

The system exits behind the passenger rear tire with dual 4in polished slash-cut tips. It connects to OEM manifolds or a Stainless Works header system for a complete performance exhaust setup.
