International HX Exhaust Parts

Frequently Asked Questions About International HX Exhaust Parts

What exhaust pipe sizes and configurations are available for International HX trucks?

International HX exhaust systems typically come in 5-inch and 6-inch diameter options. Most HX models from 2016 onwards use 5-inch systems as standard, while heavy-duty applications may require 6-inch. We offer straight pipes, curved stacks, miter-cut ends, and turn-down tips. DPF-back and turbo-back configurations are available depending on your truck's emission requirements and model year.

Will aftermarket exhaust parts void my International HX warranty or affect emissions compliance?

Installing EPA-compliant aftermarket exhaust components that don't modify or remove emission control devices (like the DPF or SCR systems) typically won't void your warranty. However, any modifications forward of the DPF or alterations to emission components can affect both warranty coverage and DOT compliance. We recommend checking with your dealer before installing turbo-back systems on trucks still under warranty.

What's the difference between aluminized steel and 304 stainless steel exhaust parts for my HX?

Aluminized steel exhaust parts offer good corrosion resistance at a lower price point and typically last 3-5 years depending on your operating conditions. 304 stainless steel provides superior corrosion resistance, especially in salt-heavy environments, and can last 7-10 years or more. Stainless steel also maintains its appearance better and handles higher exhaust temperatures without discoloration, making it ideal for show trucks or severe-duty applications.

Do I need special tools or professional installation for International HX exhaust upgrades?

Most bolt-on exhaust components like stacks, tips, and DPF-back pipes can be installed with basic hand tools in 1-2 hours. You'll need appropriate clamps (we recommend stainless band clamps for best results), and possibly a reciprocating saw if removing old components. Turbo-back systems or modifications requiring new hangers may need welding equipment and professional installation to ensure proper fitment and prevent exhaust leaks.

How do I determine the correct exhaust parts for my specific International HX model year?

International HX exhaust configurations vary by model year and engine option. Check your OEM's 8th digit for engine code, and note whether you have a single or dual exhaust system. 2017-2019 models with Cummins X15 engines use different mounting positions than 2020+ models. Trucks with factory dual exhausts require specific Y-pipe configurations. When ordering, have your OEM ready or check the existing pipe diameter where it exits the DPF or muffler.
