Mack CX Truck Exhaust Parts

Frequently Asked Questions About Mack CX Truck Exhaust Parts

Will these exhaust parts fit my specific Mack CX model year?

Our Mack CX exhaust parts are designed to fit CX Vision models from 2000-2015. However, there can be variations between early and late production years. We recommend checking your VIN or calling us with your truck's specific year and engine type (such as Mack MP7 or MP8) to ensure proper fitment. Pay special attention if you have a 2007-2010 model, as these years may have different mounting bracket configurations.

What's the difference between aluminized and chrome exhaust stacks, and which lasts longer?

Aluminized steel stacks offer good corrosion resistance at a lower price point and typically last 3-5 years with proper care. Chrome stacks provide superior shine and durability, often lasting 7-10 years, but require regular polishing to maintain their appearance. For trucks operating in harsh winter conditions with road salt exposure, we recommend chrome or 304 stainless steel options for maximum longevity.

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

Most exhaust stack and pipe replacements can be completed with standard hand tools including socket sets, pipe clamps, and exhaust hangers. However, DPF (Diesel Particulate Filter) and muffler replacements often require cutting and welding, which we recommend having done professionally. Installation typically takes 2-4 hours for stacks and pipes, while complete system replacements may require 6-8 hours of labor.

What exhaust stack heights and diameters are available for the Mack CX?

We stock 5-inch and 6-inch diameter stacks in heights ranging from 48 inches to 96 inches. The most popular configuration for Mack CX trucks is 5-inch diameter with 60-inch or 72-inch height. Curved stacks are available with 45-degree and 90-degree bends. Remember that some states have height restrictions, so check local regulations before selecting stacks over 72 inches.

How do I know when my DPF filter needs replacement versus cleaning?

If your check engine light shows DPF-related codes or you notice decreased fuel economy and power, first try a professional DPF cleaning service. However, if the filter has over 250,000 miles, shows physical damage like cracks or melting, or fails to improve after cleaning, replacement is necessary. Our replacement DPF filters meet EPA standards and come with installation gaskets and clamps included.
