Frequently Asked Questions About Freightliner Cascadia 113/125 Exhaust Parts
Will these exhaust parts fit my specific Cascadia model year?
Our Freightliner Cascadia 113/125 exhaust parts are designed to fit model years 2008-2017. However, there are variations between early models (2008-2011) and later models (2012-2017) due to EPA regulation changes. Always verify your truck's exact model year and engine type before ordering. If you're unsure, contact us with your OEM number and we'll help confirm compatibility.
What's the difference between aluminized and stainless steel exhaust components?
Aluminized steel exhaust parts offer good corrosion resistance at a lower price point and typically last 3-5 years depending on conditions. Stainless steel components cost more upfront but provide superior durability, lasting 7-10 years or more. If you operate in harsh weather conditions or areas with road salt, stainless steel is worth the investment. Aluminized works well for milder climates and shorter ownership periods.
Can I install these exhaust parts myself or do I need a shop?
Most straight pipe sections and mufflers can be installed with basic tools and mechanical knowledge. You'll need proper jack stands, clamps, and potentially a reciprocating saw for removal of old parts. DPF and DOC replacements require more expertise and often specialized diagnostic tools for proper calibration. Installation typically takes 2-4 hours for basic components, but allow extra time if you're dealing with rusted or seized parts.
What diameter exhaust pipes do I need for my Cascadia?
Most Cascadia 113/125 models use 5-inch diameter exhaust systems, but some configurations may have 4-inch systems. The diameter depends on your engine size and emissions equipment. DD13 and DD15 engines typically use 5-inch, while some ISX configurations may vary. Check your existing exhaust system or reference your build sheet to confirm the correct diameter before ordering.
How do aftermarket exhaust parts affect my warranty and emissions compliance?
EPA-compliant aftermarket parts that match OEM specifications won't void your warranty when properly installed. However, removing or modifying emissions equipment like DPF or DOC systems is illegal for on-highway use and will result in compliance issues. Replacement mufflers and pipes that maintain factory emissions equipment are perfectly legal. Always ensure any exhaust modifications comply with federal and state regulations for your operating areas.
