Kits are available with stylish long-drop or OE-style elbows for Glider, pre-DPF, and post-DPF emissions setups.

Our chrome, stainless, and chrome-plated exhaust kits come with elbows, clamps, mount grommets, spools, and the unique chrome stack top style for your rig.

Frequently Asked Questions About Exhaust Kits

What is included in a semi-truck exhaust kit?

Most exhaust kits include the major components needed to complete a stack setup, such as exhaust pipes, elbows, mounting brackets, and clamps. Depending on the kit, you may also get heat shields or mounting hardware. Always check the product listing to confirm exactly what pieces are included, since kits vary by manufacturer and application.

Will this exhaust kit fit my truck make and model?

Exhaust kits are typically designed for specific truck makes, models, and engine setups, so fitment can vary widely between brands like Peterbilt, Kenworth, or Freightliner. Before purchasing, check the diameter, length, and mounting configuration listed for each kit against your truck's existing exhaust system or OEM specifications to confirm compatibility.

What materials and finishes are available for exhaust kits?

Exhaust kits are commonly available in aluminized steel, stainless steel, and chrome finishes. Aluminized steel offers good heat resistance at a lower cost, while stainless steel and chrome options provide added corrosion resistance and a polished look for drivers who want their rig to stand out. Choosing the right material often comes down to budget, climate, and desired appearance.

Can I install an exhaust kit myself, or do I need a professional?

Many drivers and shop technicians install exhaust kits themselves, especially if they have experience with basic hand tools and truck maintenance. That said, proper alignment, secure mounting, and correct clearance from cab and frame components are important for safety and performance, so if you are unsure about any step, having a qualified technician handle the installation is a good idea.

Will a new exhaust kit affect my truck's emissions compliance?

Exhaust kits themselves are generally aftermarket replacement components for the visible stack and piping, but any modification to your exhaust system should be checked against DOT and EPA regulations as well as your state's specific requirements. If your kit alters the original exhaust path or removes emissions-related equipment, confirm compliance before installation to avoid potential violations.
