Peterbilt 587 Exhaust Parts

Frequently Asked Questions About Peterbilt 587 Exhaust Parts

Will these exhaust stacks fit my specific year Peterbilt 587?

Our exhaust parts are designed to fit Peterbilt 587 models from 2008-2017. However, some variations exist between model years, particularly in mounting bracket locations and DPF/DEF equipped trucks (2011 and newer). We recommend checking your existing exhaust diameter and mounting style before ordering. Most 587s use 5-inch diameter systems, but some specialty configurations may differ. Contact our tech support team with your OEM if you need help verifying compatibility.

What's the difference between chrome and stainless steel exhaust stacks?

Chrome-plated stacks offer a mirror-like finish at a lower initial cost but require regular polishing and may show pitting or rust over time, especially in harsh weather conditions. 304 stainless steel stacks cost more upfront but maintain their appearance longer with minimal maintenance and resist corrosion better. For trucks operating in northern climates with road salt exposure, stainless steel typically provides better long-term value despite the higher price point.

Can I install these exhaust parts myself, or do I need a shop?

Most exhaust stack replacements can be completed by experienced DIY mechanics with basic tools including wrenches, a sawzall for removing old parts, and proper jack stands. The job typically takes 2-4 hours. However, if you're modifying exhaust routing, adding elbows, or working with DPF/DEF systems, professional installation is recommended to avoid check engine lights or compliance issues. Always ensure proper exhaust clamp torque (typically 60-80 ft-lbs) to prevent leaks.

How do I choose between straight pipes and curved exhaust stacks?

Straight pipes provide maximum exhaust flow and a classic look but may direct exhaust toward your trailer. Curved stacks angle exhaust away from the truck and trailer, reducing soot buildup on equipment. West Coast style curves add 6-12 inches of height, while bull hauler styles can add up to 24 inches. Consider your typical loads, garage clearance requirements, and state height restrictions (typically 13'6") when selecting stack style and height.

Why are my new chrome stacks already showing discoloration?

Blue or gold discoloration on chrome exhaust parts is normal and caused by extreme heat, especially near the engine. This typically appears within the first few hundred miles and doesn't indicate a defect. To minimize discoloration, avoid extended idling during the break-in period and ensure your engine isn't running excessively hot. For stacks already discolored, specialized chrome polish for high-heat applications can reduce the appearance, though some discoloration near the base is unavoidable.
