Frequently Asked Questions About Kenworth T660 Exhaust Parts

What year models of Kenworth T660 are these exhaust parts compatible with?

Our Kenworth T660 exhaust parts are designed to fit model years 2008-2016. However, compatibility can vary based on your specific engine configuration (Cummins ISX, Caterpillar C15, or Paccar MX). We recommend checking your OEM or calling our technical support team at 1-888-875-7787 to confirm fitment for your specific truck before ordering.

Are these exhaust stacks made from 304 or 409 stainless steel, and what's the difference?

We carry both 304 and 409 stainless steel options. The 409 stainless steel stacks are more budget-friendly and offer good corrosion resistance for most applications. The 304 stainless steel options provide superior corrosion resistance and maintain their polish better over time, making them ideal for show trucks or harsh weather conditions. All chrome-plated options use heavy-duty steel bases with triple-chrome plating for maximum shine and durability.

Do I need special tools or professional installation for these exhaust components?

Most exhaust stack installations can be completed with basic hand tools including wrenches, sockets, and clamps. Typical installation takes 2-4 hours depending on your experience level. For muffler replacements or complete exhaust system overhauls, you may need a reciprocating saw for removal and possibly welding equipment for certain configurations. We provide detailed installation instructions with each product, and our tech support can walk you through any challenges.

What's the difference between curved, straight, and miter cut exhaust stacks?

Straight stacks provide a classic, traditional look and are the easiest to install. Curved stacks angle away from the cab, reducing soot buildup on your truck and trailer while providing better aerodynamics. Miter cut stacks feature an angled top cut that directs exhaust away from the truck at typically 15, 30, or 45-degree angles. Your choice depends on personal preference, local regulations, and whether you frequently haul tall loads that might be affected by exhaust direction.

How do I prevent my new chrome stacks from bluing or discoloring?

Chrome stacks can blue or discolor from extreme heat, especially during heavy loads or extended idling. To minimize this, ensure proper exhaust flow by checking for restrictions in your system. Consider using exhaust wrap on the first 12-18 inches inside the stack where heat is most intense. Regular cleaning with chrome polish and avoiding excessive idling can also help maintain appearance. For trucks that see heavy-duty use, consider our polished stainless options which handle heat discoloration better than chrome.
