aFe 49-04041 ATLAS uses 5-inch ALUMINIZED STEEL tubing behind the retained DPF. The exact manufacturer manual explicitly identifies this selection as NO TIP and lists three pipe sections with three band clamps. Old-tailpipe removal requires a cut, and some cab arrangements require trimming the new mid-pipe.
2011-2016 Chevrolet Silverado HD / GMC Sierra HD with 6.6L LML Duramax turbodiesel, per the exact-selection manufacturer manual. DOES NOT FIT 2016 3500HD WITH NOx SENSOR, as explicitly printed in that manual. Its all-wheelbase heading is subject to its cab-dependent trimming procedure and the sensor exclusion; it does not establish every chassis arrangement. Existing named-grade bounds remain; Silverado 3500 HD LT 2011-2016 and Sierra 2500 HD WT 2011-2014 are restored from the exact selected current retailer table. No 2016 sensor-equipped 3500HD compatibility is inferred from a broad named-grade row.

THREE ALUMINIZED-STEEL sections: mid-pipe 05-42784, over-axle 05-42785 and tailpipe/turnout 05-42769. TWO AS band clamps 05-41043 and ONE 4-inch AS band clamp 05-41042 are shown. This exact NONSUFFIX selection is explicitly NO TIP. Shared black/polished tip options and SS main sections/clamps belong to other selections and are not included extras. Reuse original factory isolation mounts and gasket. No new muffler, DPF, converter, sensor, intake filter, intake coupler or decorative tip is listed for this selected configuration.

Which applications and sensor exclusion apply?2011-2016 Chevrolet Silverado HD / GMC Sierra HD with 6.6L LML Duramax turbodiesel, per the exact-selection manufacturer manual. DOES NOT FIT 2016 3500HD WITH NOx SENSOR, as explicitly printed in that manual. Its all-wheelbase heading is subject to its cab-dependent trimming procedure and the sensor exclusion; it does not establish every chassis arrangement. Existing named-grade bounds remain; Silverado 3500 HD LT 2011-2016 and Sierra 2500 HD WT 2011-2014 are restored from the exact selected current retailer table. No 2016 sensor-equipped 3500HD compatibility is inferred from a broad named-grade row.
Is a black or polished tip included?NO. The exact nonsuffix selection is expressly NO TIP in the manufacturer manual. Black/polished tips and stainless main-pipe alternatives in the shared diagram belong to different selections.
Does removal require cutting?YES. The exact manual requires measuring FOUR INCHES from the rear hanger at the end of the DPF system, then marking and cutting the ORIGINAL TAILPIPE for separate removal. The factory-location design does not eliminate that removal cut.
When is the new mid-pipe trimmed?REGULAR CAB and QUAD CAB / SHORT BED require trimming the new mid-pipe at the end OPPOSITE THE SLIP FIT. CREW CAB / LONG BED uses it AS IS. No fixed numeric trim length is provided.
Which original mounts and over-axle position apply?Reuse the ORIGINAL GASKET and FACTORY ISOLATION MOUNTS. Position the over-axle bend CLOSER TO DRIVE SHAFT to increase tailpipe-to-shock clearance, and maintain the manual body-panel clearance of 1/2 to 1 inch.
What torque and recheck are specified?No numeric clamp or flange torque is printed. Align and tighten applicable connections, then re-tighten ALL EXHAUST COMPONENTS after the first 50-100 miles.
Are numeric gains or emissions clearance proven?No actual dyno or bench-flow chart for this exact selection was located. No numeric horsepower, torque, EGT or fuel-economy gain, or cabin-drone guarantee, is independently established. The original Non-CARB restriction is retained. An exact current nonsuffix product page and current exact-selection emissions determination were not located; no sibling tip-equipped product disclaimer is substituted and no blanket jurisdiction clearance is made.
