What are the differences between aluminized and stainless steel exhaust systems for my Kenworth?
Aluminized steel exhaust systems offer good corrosion resistance at a lower price point and typically last 3-5 years under normal conditions. Stainless steel systems, particularly 409 or 304 grade, provide superior durability lasting 7-10 years or more, resist road salt better, and maintain their appearance longer. While stainless costs 40-60% more upfront, it often proves more economical for high-mileage applications or harsh environments.
How do I determine the correct exhaust stack size and configuration for my specific Kenworth model?
Check your truck's door jamb sticker for the engine model and year, then measure your current stack diameter at the base. Most W900 models use 5-inch or 6-inch stacks, while T680 and T880 typically use 5-inch. Verify whether you need straight cut, curved, or miter cut tops based on your cab configuration. For sleeper cabs, ensure adequate clearance - generally 6-8 inches minimum between the stack top and any cab components.
What tools and additional parts do I need for a complete exhaust system installation?
You'll need basic hand tools, a reciprocating saw or exhaust cutter, and potentially a torch for removing rusted components. Essential additional parts include exhaust clamps (typically 5 or 6-inch band clamps), high-temperature exhaust sealant, new exhaust gaskets, and mounting brackets if yours are worn. Budget 3-5 hours for a complete system replacement, or 1-2 hours for stack-only replacement. Professional installation typically runs $300-500 for labor.
Which chrome stack brands hold up best against bluing and discoloration?
Triple chrome-plated stacks from Grand Rock, Dynaflex, and Lincoln Chrome consistently receive high marks for blue-resistance. These manufacturers use nickel underplating that helps prevent bluing at normal operating temperatures. For maximum protection, consider stacks with heat shields or double-wall construction. Note that any chrome will eventually blue if exposed to extreme heat (over 800?F continuously), but quality brands typically maintain appearance for 2-3 years with regular cleaning.
Can I mix different brand exhaust components, or should I stick with one manufacturer?
Most exhaust components are interchangeable between major brands as long as diameters match (5-inch to 5-inch, etc.). However, some proprietary connections exist - particularly with certain muffler designs and flex pipe configurations. Mixing brands is generally fine for straight pipes, stacks, and elbows, but verify fitment for mufflers and specialized components. When possible, using matched components from one manufacturer ensures optimal fit and may preserve warranty coverage.
