Frequently Asked Questions About International LoneStar Chrome Stacks & Tops

What exhaust pipe sizes are compatible with LoneStar chrome stacks and will they fit my specific model year?

Our International LoneStar chrome stacks are designed to fit 5-inch exhaust systems, which is the standard size for most LoneStar models from 2008 to present. These stacks feature a 5-inch OD inlet that slides over your existing exhaust pipe. For trucks with aftermarket exhaust modifications, please measure your current pipe diameter before ordering. The mounting brackets included are specifically engineered for the LoneStar's frame rails and cab configuration.

Are these stacks made from real chrome or chrome-plated steel, and how long will the finish last?

Our LoneStar stacks are constructed from heavy-gauge steel with a triple-chrome plating process that includes copper, nickel, and chrome layers. This provides superior corrosion resistance compared to standard chrome plating. With proper maintenance (regular washing and occasional polishing), drivers typically report the chrome finish maintaining its mirror shine for 5-7 years in normal conditions. For harsh winter climates with heavy road salt exposure, we recommend our stainless steel options for maximum longevity.

Can I install these stacks myself, and what tools or modifications are required?

Yes, most customers successfully complete the installation in 2-3 hours with basic tools. You'll need a socket set, drill with metal bits, and a sawzall or exhaust pipe cutter if you need to trim your existing exhaust. The stacks come with universal mounting brackets and detailed instructions. No welding is required for standard installations. However, some customers prefer to add additional support brackets or have a muffler shop perform the final alignment for a perfect fit.

What's the difference between straight cut, curve cut, and miter cut stack tops?

Straight cut tops provide a classic, clean look with the exhaust exit perpendicular to the ground. Curve cut (also called turnout) tops direct exhaust away from your trailer, reducing soot buildup on refrigerated units or van trailers. Miter cut tops feature an angled cut that adds an aggressive appearance while providing some exhaust deflection. The choice is primarily aesthetic and functional based on your hauling needs - all three styles flow equally well and don't affect engine performance.

Will adding chrome stacks affect my engine performance or fuel economy?

When properly installed, chrome stacks have minimal impact on engine performance or fuel economy. The key is maintaining proper exhaust backpressure by not restricting the exhaust flow. Our stacks are designed with smooth internal surfaces and proper diameter sizing to match OEM specifications. Some drivers even report slight improvements in exhaust gas temperatures (EGTs) due to better heat dissipation. Always ensure your stack height complies with state regulations - most states require the exhaust exit to be above the cab height.
