You'd think that being made from super-durable, mandrel-bent 409 stainless steel tubing and sporting a 1/2 inch thick precision ported and machined flange was enough... but there's more. The header is fortified with a "Revolver" collector which features Banks' patented "Power Pickle®" exhaust collector technology. The Revolver manifold features a longer center tube in the 6-cylinder exhaust collector which captures exhaust pulse action and turns it into massive torque throughout the operating range. Powering through the roughest terrain is no longer a question.And cracking... a thing of the past when you arm your Jeep with Banks TorqueTubes.Virtually indestructible 100% Stainless SteelMandrel-formed tubes tune exhaust flow for maximum torqueMaximize exhaust extractionFlanges welded on both sides, then milled flatSeamless high-velocity collectorPulls exhaust and slashes backpressureHeavy 400 stainless replaces crack-prone stock pieceSelf-aligning exhaust seal won't compress or blow outBolts easily to stock exhaust1/2 inch thick flanges won't warp/flexPrecision port-match to cylinder headUnrestricted Exhaust PortsEmissions Compliant: D-161-105US Patent #8,468,812 B1
