Banks Power Exhaust Header System 51327

4.0L 6-CYL: 1991-1999 WRANGLER, 1991-1998 CHEROKEE, 1991-1992 COMANCHE With more power, quicker acceleration, and tougher construction than ever, the new Banks Revolver® out muscles any competitive exhaust manifold: period! 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 Steel Mandrel-formed tubes tune exhaust flow for maximum torque Maximize exhaust extraction Flanges welded on both sides, then milled flat Seamless high-velocity collector Pulls exhaust and slashes backpressure Heavy 400 stainless replaces crack-prone stock piece Self-aligning exhaust seal won't compress or blow out Bolts easily to stock exhaust 1/2 inch thick flanges won't warp/flex Precision port-match to cylinder head Unrestricted Exhaust Ports Emissions Compliant: D-161-105 US Patent #8,468,812 B1
