Pick-up stacks are for the big rig look. Since we are the area's only 4” mandrel bender, we do not use universal kits. We make our own installation kit for your pick-up in aluminized or stainless steel tubing. We have a variety of stack styles from 4” to 7” diameter made by Grand Rock Truck Exhaust. We are a Grand Rock Truck Exhaust dealer. If there is something unique you are looking for, let us know!
