Frequently Asked Questions About International 9300/9370 Chrome Stacks & Tops

Will these chrome stacks fit my specific International 9300 or 9370 model year?

Most chrome stacks and tops are designed to fit International 9300 and 9370 models from 1987-2007. However, there can be variations based on your specific exhaust configuration and mounting style. We recommend checking your current stack diameter (typically 5" or 6") and mounting type (band clamp or flanged) before ordering. If you're unsure, contact us with your VIN or current stack measurements for verification.

What's the difference between 304 and 430 stainless steel chrome stacks?

304 stainless steel offers superior corrosion resistance and maintains its shine longer, making it ideal for harsh weather conditions and coastal areas. 430 stainless steel is more budget-friendly and still provides good durability for most applications. Both grades polish to a mirror finish, but 304 typically requires less maintenance to keep its chrome-like appearance over time.

How difficult is the installation process, and what tools will I need?

Installation typically takes 1-2 hours and requires basic hand tools including wrenches, a socket set, and potentially a sawzall if you're replacing existing stacks. Most chrome stacks use either band clamps or flanged connections. The main challenges involve proper alignment and ensuring a leak-free seal. Some installations may require minor bracket adjustments or new mounting hardware, which we can supply separately.

What stack styles and lengths work best for International 9300/9370 trucks?

Popular styles include straight pipes, curved tops, bull hauler stacks, and miter cut designs. For hood clearance on 9300/9370 models, we recommend 48" to 60" lengths for standard applications, though some drivers prefer 72" stacks for a more aggressive look. Curved and angled tops help direct exhaust away from the cab and trailer, while straight cuts offer a classic appearance.

How do I maintain the chrome finish and prevent discoloration?

Regular cleaning with chrome polish and a microfiber cloth every 2-4 weeks prevents buildup and discoloration. Avoid abrasive cleaners that can scratch the surface. For heat discoloration near the base, use a specialized stainless steel cleaner. Installing a heat shield or wrap on the first 12-18 inches can significantly reduce bluing from exhaust heat. In winter conditions with road salt, increase cleaning frequency to prevent corrosion.
