The aFe MACH Force-Xp 3in downpipe for 2011–2015 GM trucks with the 6.6L LML V8 turbo replaces the restrictive factory downpipe with mandrel-bent stainless tubing for improved exhaust flow and quicker turbo spool. CNC-machined V-band flanges provide a 360-degree sealing surface and both inside and out surfaces are ceramic coated to help reduce EGTs. The 409 stainless construction is fully TIG-welded for durability.
