International 9300/9370 Chrome Stacks & Tops

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

What exactly are exhaust stacks and stack tops?

Exhaust stacks are the vertical pipes that carry exhaust up and away from the cab on the International 9300 and 9370, while stack tops (sometimes called mitered tops, turnouts, or rain caps) are the finishing pieces that attach to the top of the stack to direct airflow and add a finished look. This category covers replacement and upgrade chrome stacks and the various top styles used to complete the exhaust system on these trucks.

Will these stacks and tops fit my International 9300 or 9370?

Most stacks and tops in this category are designed to match the common diameters and mounting setups used on the 9300 and 9370 series, but exhaust configurations can vary based on engine, model year, and any prior aftermarket modifications. Always check the listed diameter, length, and mounting style against your current exhaust setup before ordering, and measure your existing stack if you are unsure.

What is the chrome finish made of, and how long will it last?

These stacks and tops are typically constructed from stainless steel with a chrome-plated or polished finish, chosen for durability and resistance to the heat and weather exposure exhaust components deal with daily. Regular washing and polishing will help maintain the shine over time, especially in areas with road salt or heavy grime, since exhaust heat and road film can dull chrome faster than other chrome trim on the truck.

Can I install these myself, or do I need a shop?

Many drivers and owner-operators install stacks and tops themselves using basic hand tools, since the job usually involves loosening clamps, removing the old stack or top, and securing the new piece in the same location. That said, if your stack ties into elbows, flex sections, or brackets that are rusted, damaged, or difficult to access, having a shop handle the installation can save time and reduce the risk of a poor seal or fitment issue.

Are there height or noise regulations I need to consider?

Exhaust stack height, angle, and placement can be subject to state or local regulations, and rules vary depending on where you operate. Before installing a stack that changes your truck's height or exhaust routing, check the regulations in your operating area and any company or fleet requirements to make sure your setup stays compliant.
