Frequently Asked Questions About Freightliner Century 112/120 Exhaust Parts

Will these exhaust parts fit my specific Century model year?

Most aftermarket exhaust components for the Century 112/120 are designed to fit model years 1996-2011. However, there are variations between early models (1996-2004) and later models (2005-2011), particularly in mounting bracket locations and pipe diameters. Always verify your truck's exact model year and engine type (Detroit, Caterpillar, or Cummins) before ordering, as exhaust routing can differ significantly between engine configurations.

What's the difference between aluminized and stainless steel exhaust parts?

Aluminized steel exhaust parts typically last 3-5 years and cost about 40% less than stainless steel options. They work well for trucks in dry climates or those with regular maintenance schedules. Stainless steel parts can last 7-10 years or more and resist corrosion better in wet, salty conditions. For Century trucks operating in northern states or coastal areas, the extra investment in stainless steel often pays for itself through extended service life.

Can I install these exhaust parts myself, or do I need special tools?

Basic exhaust stack and tip replacements can typically be done with standard hand tools in 1-2 hours. However, complete exhaust system overhauls involving manifolds, turbo pipes, or flex pipes often require specialized equipment like pipe expanders, cutting tools, and heavy-duty jack stands. Many Century owners report that Y-pipe and muffler installations are particularly challenging due to limited clearance and may require loosening engine mounts for proper fitment.

Which exhaust stack styles and sizes work best for Century 112/120 trucks?

The most common stack sizes for Century trucks are 5-inch and 6-inch diameters, with 5-inch being standard on most factory configurations. Straight chrome stacks remain the most popular choice, though curved and mitered styles are available for custom looks. Stack heights typically range from 48 to 72 inches, with 60-inch stacks providing the best balance of appearance and practical bridge clearance for most applications.

Why are my new exhaust parts not fitting properly even though they're listed as compatible?

Century trucks often underwent modifications during their service life, including frame stretches, suspension changes, or non-standard exhaust routing from previous repairs. Additionally, some aftermarket parts are designed as "universal fit" and may require minor adjustments like trimming pipes or drilling new mounting holes. Before installation, compare your existing exhaust layout to factory diagrams, as previous owners may have installed custom configurations that affect fitment of replacement parts.
