FAQ
Is this a DPF-back system and will it trigger a check engine light?
Yes—this is a filter-back (DPF-back) system that installs after the factory DPF. It retains all emissions hardware and does not require tuning; no CEL is expected when installed correctly.
Will it fit both LML (2011–2016) and L5P (2017–2019) trucks?
Yes. It’s listed for 2011–2019 2500/3500 HD Duramax models, covering LML and L5P on Crew/Ext cab configurations.
Does it include an exhaust tip?
No. Tips are sold separately. Popular choices include the T5124, T5052, and T5154BLK.
What’s the difference between T409 and aluminized steel?
T409 stainless (this kit) offers superior corrosion resistance versus aluminized steel, especially in salted climates. For a lower-cost alternative, see S60360AL.
