Frequently Asked Questions About Peterbilt 386 Chrome Stacks & Tops

What are the differences between straight cut, curved, and mitered chrome stack styles for my Peterbilt 386?

Straight cut stacks offer a classic, traditional look with a flat top edge that sits perpendicular to the stack body. Curved or turnout stacks feature a bent design that directs exhaust away from your trailer, reducing soot buildup on your equipment. Mitered (angle cut) stacks have a slanted top opening, typically cut at 15 or 30-degree angles, which helps prevent rain from entering while adding a custom appearance. Most Peterbilt 386 owners prefer 5-inch or 6-inch diameter stacks, with mitered cuts being the most popular for both style and functionality.

Will these chrome stacks fit my specific Peterbilt 386 model year, and what mounting hardware do I need?

Our chrome stacks are designed to fit all Peterbilt 386 models from 2005-2015. The mounting process typically uses your existing exhaust brackets and clamps. For 5-inch stacks, you'll need 5-inch exhaust clamps (sold separately), while 6-inch stacks require 6-inch clamps. Some installations may require additional elbow pipes or reducers depending on your current exhaust configuration. We recommend measuring your current exhaust outlet diameter before ordering to ensure proper fitment.

How difficult is it to install chrome stacks on a Peterbilt 386, and can I do it myself?

Installation typically takes 2-3 hours and can be completed with basic hand tools. You'll need to remove your existing stacks or exhaust tips, clean the mounting area, and secure the new chrome stacks using heavy-duty exhaust clamps. The most challenging part is usually aligning the stacks perfectly vertical and ensuring they're evenly spaced. Many customers successfully complete this as a DIY project, though having a helper makes positioning easier. Professional installation typically costs $150-300 if you prefer to have a shop handle it.

What's the difference between 304 and 430 stainless steel chrome stacks, and which should I choose?

304 stainless steel stacks feature a higher nickel content, providing superior corrosion resistance and maintaining their mirror finish longer, especially in harsh weather conditions or coastal areas with salt exposure. 430 stainless steel stacks are more affordable and still offer good durability for most applications, though they may show slight discoloration over time near the exhaust outlet. For Peterbilt 386 trucks operating in northern states or near coastal regions, we recommend 304 stainless. For trucks primarily in dry climates, 430 stainless provides excellent value.

How do I maintain the chrome finish on my stacks, and what about heat shields or stack guards?

To maintain your chrome stacks' mirror finish, clean them every 2-3 weeks using a quality chrome polish and microfiber cloth. Avoid abrasive cleaners that can scratch the surface. For the inside of the stacks, use a long-handled brush with degreaser to remove soot buildup. Heat shields are recommended if your stacks are close to air lines or wiring, typically needed for stacks mounted within 6 inches of these components. Stack guards (or stack screens) help prevent debris from entering your exhaust system and are especially useful for trucks that sit idle for extended periods.
