2015.5-2016 GM Duramax LML Catalytic Converter / DPF Section – Low Miles, Garage Kept

Price: $350

Up for sale is the main catalytic converter / DPF portion from a complete 2015.5-2016 LML Duramax exhaust + DEF system.

This is the large emissions canister section with attached piping and flanges — the key piece for emissions compliance.

Removed early with very low miles.

Garage kept, original factory stickers still visible 3-bolt flange style (2015.5-2016 specific).

Compatible with 2011-2015.5 engines with downpipe swap

Removed from short bed 4-door truck.

Great usable condition — no major damage

This was part of my full system originally listed. I sold the other pieces (tailpipe, DEF components) separately.

Perfect for replacing a bad cat/DPF to pass emissions or as a stock take-off.

Local pickup only in Ogden area.

Cash preferred.

Message with questions or to see it in person. More photos available.
