Why Upgrade Your FLT Cabover Exhaust System?

Swapping in new exhaust components helps your cabover breathe better, run cooler, and burn cleaner. You’ll see real benefits on the road: - Improved airflow and horsepower  - Reduced emissions and exhaust noise - Longer-lasting engine performance - Custom style with chrome stacks and tips It’s more than just a repair—it’s a smart upgrade for any serious trucker who wants to keep their FLT running strong. What’s in the Lineup? - Chrome Stacks & Elbows: Give your rig that signature cabover style  - Mufflers & DPF Systems: Reduce engine noise and filter harmful emissions - Clamps, Brackets & Mounting Hardware: Keep everything secured tight - Replacement Piping: Direct exhaust gases efficiently - Complete Exhaust Kits: Everything you need in one go
These parts are built tough for heavy-duty, commercial use and made to fit the unique frame and layout of Freightliner FLT Cabover trucks. Add some power to your exhaust upgrade with Freightilner FLT engine performance parts – like exhaust manifolds and turbochargers – for a comprehensive optimization. While you’re under the hood swapping out exhaust components, consider throwing in some FLT Cabover truck heating parts.

Frequently Asked Questions About Freightliner FLT Cabover Exhaust Parts

What years and models of Freightliner FLT cabovers are these exhaust parts compatible with?

Our exhaust parts are designed to fit Freightliner FLT cabover models from 1980 through 1991, including the FLT86, FLT75, and FLT64 series. Each product listing specifies exact model compatibility. For trucks with aftermarket modifications or custom exhaust routing, we recommend measuring your existing system before ordering to ensure proper fitment.

Are these exhaust stacks chrome-plated steel or stainless steel, and what's the difference in durability?

We offer both chrome-plated steel and 304 stainless steel options. Chrome-plated stacks provide a mirror finish at a lower cost but may require more maintenance and can develop rust spots over time, especially in salt-heavy regions. Stainless steel stacks cost more initially but resist corrosion better and maintain their appearance longer with minimal upkeep. Both options are 16-gauge thickness for durability.

Do I need special tools or professional installation for these exhaust components?

Most exhaust stack replacements can be completed with standard hand tools including wrenches, sockets, and clamps. However, some installations may require cutting or welding, particularly when replacing elbows or modifying exhaust routing. We include detailed instructions with each part. For complete system overhauls or if you're uncomfortable with exhaust work, professional installation typically takes 2-4 hours.

What diameter exhaust stacks fit the FLT cabover, and can I upgrade from my current size?

Standard FLT cabovers came with 5-inch diameter exhaust systems, though some models used 4-inch. You can upgrade to a larger diameter, but this requires matching elbows, reducers, and potentially new mounting brackets. MoOEMg from 4-inch to 5-inch typically improves exhaust flow and sound but requires verifying clearance between the stack and cab.

How do curved versus straight stacks affect performance and appearance on FLT cabovers?

Curved stacks direct exhaust away from the cab, reducing soot buildup on your truck and trailer while providing the classic cabover look. Straight stacks offer easier installation and slightly better exhaust flow but may deposit more soot on your equipment. Neither significantly impacts engine performance. The choice is primarily aesthetic and based on your maintenance preferences.
