4-inch constant-diameter pipes with Straight-thru muffler cuts back pressure up to 81 Percent. Turbo Back System. 5-inch Chrome or Cerakote Black Tip. Excursions: Banks 4 inch Monster turbo-back stainless steel exhaust features streamlined turbine-outlet pipe, intermediate pipe and tailpipe all formed of stainless, heavy-wall tubing with constant-diameter bends to maximize flow, lower exhaust gas temps and slash backpressure up to 81 percent. (Available with or without a cast, large-bore Power Elbow housing.). The polished-stainless Monster muffler features a straight-through 4 inch diameter flow-path with a Banks-designed expansion chamber to dissipate the annoying mid-range exhaust drone that affects most straight-through designs. The muffler utilizes spun ceramic, very-high-temperature packing, more than doubles stock exhaust flow, and delivers an authoritative – but never intrusive – exhaust sound. And the 5 inch polished rolled-edge tip has an adjustable clamp for positioning on tailpipe. Get it in your choice of chrome-over stainless or high temp black! (And to help keep it looking good, there’s a 1/2 inch air gap to keep heat from tarnishing the finish)

Gale Banks talks about the exhaust manifolds for 4.0L Jeeps… Banks TorqueTube headers have been the best available power producers for quite a while. About a year ago, I applied my 5 cylinder collector patent to the ’91-99 Jeep 4.0L 6-cylinder header using a firing center tube & I Kicked My Own Ass! The NEW Revolver header matches the low end of the previous TorqueTube design & adds a ton of top end power. Have a look at the wheel dyno results. Above 3400 rpm we’ve added power so your Jeep marches to the shift with no loss in low end torque. Add a complete Banks PowerPack Bundle & get even more! –Gale Banks
