The Quadratec® Difference
Catalog #: 17601.501
Gale Banks Engineering Part #: 51327
Description
With more power, quicker acceleration and tougher construction than ever, the new Banks Revolver™ for the '91-99 Jeep 4.0 liter 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"-thick precision ported and machined flange was enough... but there's more. This stainless manifold 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 this "Revolver."
