DESCRIPTION

Product Overview

  • 6.6L Duramax LML trucks, DPF backpressure heat-soaks the turbo, while combined EGR soot and CCV oil vapor bake into a flow-choking sludge across intake valves and intercooler lines.
  • This LML Performance Upgrade Kit eliminates all three bottlenecks at once. Combining free-flowing exhaust hardware, an EGR delete, and a CCV reroute, it slashes EGTs, restores turbo response, and keeps your intake tract completely sludge-free.

Key Features

  • Secures to early-build trucks via the V-band clamp, aligning seamlessly with the factory downpipe connection.
  • Replaces the factory DPF and CAT with a 4" performance pipe and an integrated high-flow muffler to eliminate harsh tones and highway drone.
  • Fully deletes the EGR and reroutes the CCV to keep harmful soot and oil mist out of your turbo and intercooler.
  • Bundles the exhaust, EGR, and CCV installations into a single job, saving time and labor costs around the tight rear engine bay.

FAQ

Q: How is this kit different from the non-muffler version? 

A: It adds a muffler to knock out cab drone and a CCV reroute to keep oil out of the turbo and intercooler — making it the most complete, comfortable, and protective option for LML trucks.

Q: What’s the upside of the muffler version? 

A: The integrated high-flow muffler softens harsh exhaust tones and highway drone without giving up airflow, making it a great fit for daily driving, towing, and work trucks.

Q: Will this make my truck louder? 

A: Yes, you’ll get a deeper diesel note than the factory system. The muffler version adds turbo sound and a richer tone while cutting highway drone versus a straight pipe.

Q: Can I keep my factory exhaust installed with this kit? 

A: Yes. The pipe is a direct replacement section that connects to the factory exhaust after the emissions parts are removed — no full exhaust swap required.
