Peterbilt 387 Chrome Stacks & Tops

Frequently Asked Questions About Peterbilt 387 Chrome Stacks & Tops

What exactly are chrome stacks and tops for the Peterbilt 387?

Chrome stacks are the exhaust pipes that route exhaust from the engine up and away from the cab, and "tops" refer to the chrome exhaust stack caps or tips that finish off the top of the stack. These components are both functional, directing exhaust away from the truck, and cosmetic, giving the Peterbilt 387 a polished, chromed-out look that many owner-operators prefer.

Will these stacks and tops fit my Peterbilt 387 without modification?

Most chrome stacks and tops in this category are designed to match the mounting points and diameter specifications used on the Peterbilt 387. However, exhaust setups can vary depending on engine configuration and prior modifications made to the truck, so it is important to check listed dimensions such as diameter, length, and mounting style against your current exhaust system before ordering.

What material and finish should I expect from these products?

These stacks and tops are typically constructed from stainless steel with a chrome finish, which provides corrosion resistance and a bright, reflective look. Some tops may feature additional detailing, such as turn-down or turn-out styles, so review the product description to confirm the specific finish and style you are ordering.

How do I install a new exhaust stack or top on my 387?

Installation generally involves securing the stack to the existing exhaust piping using clamps or bolted flanges, depending on the setup, and then attaching the top or cap at the upper end. While many truckers handle this as a straightforward driveway job with basic tools, we recommend having a qualified technician install or inspect the work if you are unfamiliar with exhaust systems, especially to ensure proper sealing and secure mounting.

How do I keep chrome stacks and tops looking good over time?

Regular washing with a mild soap and water solution helps prevent road grime and diesel exhaust residue from etching into the chrome. For tougher buildup or heat discoloration near the top, a dedicated chrome polish designed for exhaust components can help restore shine. Avoid abrasive pads that could scratch the chrome finish, and clean stacks periodically to prevent long-term staining.
