International S1700-S1900 Exhaust Parts

Frequently Asked Questions About International S1700-S1900 Exhaust Parts

What years and specific models do these exhaust parts fit?

Our International S1700-S1900 exhaust parts are designed to fit International S-Series trucks manufactured from 1979 through 2001. This includes all variations of the S1700, S1800, and S1900 models. However, there were some mid-year changes in exhaust routing, particularly in 1989 and 1995 models. We recommend checking your existing exhaust configuration or calling our technical support team with your OEM to ensure proper fitment, especially if you have a truck from these transition years.

Are these exhaust parts made from aluminized or stainless steel, and what is the expected lifespan?

We offer both aluminized steel and 409 stainless steel options for most S-Series exhaust components. Aluminized steel parts typically last 3-5 years under normal conditions and are more budget-friendly. Our 409 stainless steel options cost approximately 40-60% more but can last 7-10 years or longer. For trucks operating in northern states with heavy road salt exposure or in coastal areas, we strongly recommend the stainless steel option for maximum durability.

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

Most S-Series exhaust components can be installed with standard hand tools, including wrenches, sockets, and a reciprocating saw for removing old parts. The main challenges are working in tight spaces near the frame rails and properly aligning multi-piece systems. A transmission jack or exhaust hanger tool makes the job much easier. Installation typically takes 2-4 hours for a complete system. Installation hardware is included with all complete exhaust kits.

What is the difference between OEM-style and aftermarket performance exhaust options?

OEM-style replacement exhausts maintain factory specifications for backpressure and sound levels, ensuring your engine runs as designed. These are ideal for work trucks needing to meet noise ordinances. Our performance options feature mandrel-bent tubing and high-flow mufflers that can reduce exhaust gas temperatures by 50-100 degrees and improve fuel economy by 3-5%. Performance systems are noticeably louder but still meet DOT requirements. Both styles use the same mounting points and fit identically.

Do you sell individual exhaust components, or must I buy a complete system?

We stock individual components including mufflers, pipes, elbows, clamps, and hangers for the S1700-S1900 series. This allows you to replace only damaged sections rather than the entire system. Our most commonly replaced individual parts are the muffler and the over-axle pipe section, which tend to fail first. When ordering individual pieces, ensure you know whether your truck has a horizontal or vertical exhaust exit, as this affects which components you need.
