Product Description
DIAMOND EYE K4130S is a 4.0" T409 stainless DPF/Filter-back, single-exit exhaust for the 2007.5–2010 GM 6.6L Duramax LMM (all cab/bed lengths). It eliminates the restrictive factory tail section after the DPF for lower EGTs and a crisper exhaust note—without deleting emissions equipment. Includes stainless tubing and hardware; designed for durability in all climates.
FAQ: WILL THIS FIT MY TRUCK?
Yes—this system fits 2007.5, 2008, 2009, and 2010 Chevy Silverado / GMC Sierra 2500/3500 with the 6.6L Duramax LMM, any cab and bed length. Always verify model year split (2007.5+) and LMM engine before ordering.
FAQ: DOES IT INCLUDE A TIP OR MUFFLER?
This version is no-muffler. Diamond Eye notes a vented stainless tip may be included on some K4130S packages; contents can vary by batch and retailer.
FAQ: IS IT EMISSIONS-COMPLIANT?
It is a filter-back (downstream of the DPF) system and retains factory emissions equipment. Always follow local regulations.
