Product Description

It keeps emissions equipment in place while improving post-DPF flow for a deeper tone and reduced restriction. Per the manufacturer listing, this kit includes the Turbo Direct Pipe #321056 and a vented stainless tip.

FAQ: WILL THIS FIT MY TRUCK?

Yes—fits 2007.5, 2008, 2009, and 2010 Silverado/Sierra 2500/3500 with the 6.6L Duramax LMM across all cab and bed lengths. It’s a DPF/filter-back system, so factory emissions equipment remains installed.

FAQ: DOES THIS DELETE EMISSIONS COMPONENTS?

No. This is a DPF/filter-back system. It retains the DPF and other emissions hardware and replaces the exhaust after the filter for sound and flow improvements.

FAQ: WHAT’S INCLUDED?

Aluminized 4" mandrel-bent tubing, clamps/hardware, single passenger-side tailpipe, tip (vented stainless), and—per manufacturer listing—a Turbo Direct Pipe #321056.
