Frequently Asked Questions About Peterbilt 587 Chrome Stacks & Tops

What are the differences between straight-cut and curved chrome stacks for my Peterbilt 587?

Straight-cut stacks provide a classic, traditional look and are typically easier to install with standard brackets. They create a more aggressive exhaust note and are generally 5-7 inches in diameter. Curved or mitered stacks offer better aerodynamics and direct exhaust away from the trailer, reducing soot buildup. Most curved stacks for the 587 have a 15-30 degree angle. Your choice depends on whether you prioritize appearance, sound, or functionality.

Will these chrome stacks fit my specific year Peterbilt 587, and what mounting hardware do I need?

Chrome stacks designed for the Peterbilt 587 typically fit model years 2011-2017, as these share the same frame rail spacing and exhaust configurations. You'll need stack clamps (usually 5-inch or 6-inch depending on your exhaust pipe diameter), mounting brackets specific to the 587's frame rails, and potentially exhaust extensions if your current system doesn't reach the desired stack location. Always verify your exhaust pipe outer diameter before ordering.

How difficult is the installation process, and can I do it myself?

Installation typically takes 2-4 hours and requires basic mechanical skills. You'll need standard tools including wrenches, a socket set, and potentially a sawzall if you need to modify existing exhaust pipes. The most challenging part is usually aligning the stacks properly and ensuring they're level. Many drivers successfully install these themselves, but if you're uncomfortable working with exhaust systems or need to weld extensions, professional installation runs $200-400 at most truck shops.

What's the difference between 304 and 430 stainless steel chrome stacks?

304 stainless steel stacks offer superior corrosion resistance and maintain their chrome finish longer, especially in harsh weather conditions or areas with road salt. They typically cost 20-30% more but can last 10+ years with proper care. 430 stainless steel stacks are more budget-friendly and still provide good durability (5-7 years typical lifespan), but may show signs of surface rust or discoloration sooner, particularly at weld points. For long-haul drivers or those in coastal areas, 304 stainless is worth the investment.

How do I maintain the chrome finish and prevent discoloration from exhaust heat?

To maintain your chrome stacks, clean them every 2-3 weeks with a quality chrome polish and microfiber cloth. For heat discoloration (bluing) near the base, use a specialized stainless steel cleaner or fine-grade steel wool with chrome polish. Apply a high-temperature wax or sealant monthly to protect against exhaust deposits. Avoid using abrasive cleaners or coarse materials that can scratch the surface. Installing a heat shield or wrap on the first 12-18 inches can significantly reduce discoloration from exhaust temperatures.
