HQPASFY Cummins Onan Generator Exhaust Tailpipe 155-3481-02 — Direct-Fit Heat-Resistant Steel

HQPASFY 155-3481-02 is a direct-fit replacement exhaust tailpipe for compatible Cummins Onan RV generators, restoring safe exhaust routing and reliable hot-gas discharge.

If your RV's Cummins Onan generator shows a rusted, cracked, or misaligned exhaust tailpipe, this HQPASFY replacement restores proper exhaust flow and keeps high-temperature gases routed away from the unit and living areas. Engineered to match OEM dimensions and attachment points, the part replaces OE number 155-3481-02 and fits QG 5500, QG 6500, QG 7000 plus Marquis Platinum HGJAA/HGJAB models. Built from heat-resistant steel and designed for straightforward connection to the factory outlet, the kit reduces the chance of exhaust leaks and protects surrounding components.

How does this exhaust kit protect my RV and generator?

The HQPASFY exhaust tailpipe directs hot exhaust gases safely away from the generator housing and RV interior, which reduces heat exposure to nearby hoses, wiring, and appliances. Proper routing also decreases soot buildup around the generator access bay and helps prevent accidental burns during maintenance.

• OEM-style contour keeps gases moving outward, not toward the chassis.
• Heat-resistant steel prevents early deformation and cracking.
• Restores original exhaust alignment to reduce leaks.

Will this part fit my Cummins Onan QG or Marquis Platinum generator?

Yes — this exhaust tailpipe is intended as a direct replacement for models listed by Cummins Onan: RV QG 5500, RV QG 6500, RV QG 7000, and Marquis Platinum HGJAA/HGJAB. It replaces OEM part number 155-3481-02 and follows factory mounting locations to match existing flanges and clamps.

• Direct replacement for OE 155-3481-02 to match fitment and routing.
• Compatible with both QG and Marquis Platinum series identified above.
• Designed for plug-in alignment with standard clamps — no custom fabrication in most installs.

What materials and durability features does it offer?

The tailpipe is manufactured from high-temperature, rust-resistant steel to withstand repeated thermal cycles and road vibration. Its construction prioritizes longevity so you avoid frequent replacements due to corrosion, cracking, or warping under exhaust heat.

• High-quality heat-resistant steel for sustained thermal durability.
• Corrosion-resistant finish to extend service life in wet or salty conditions.
• Rugged welds and bends to resist cracking from vibration and heat cycling.

How difficult is installation and what tools are needed?

Installation is straightforward for anyone comfortable with basic RV maintenance: the pipe is designed to connect to the factory exhaust outlet using standard clamps and hardware. Most installs require common hand tools and do not need cutting or welding.

• Connects to factory outlet using standard exhaust clamps.
• Typical tools: ratchet, screwdrivers, adjustable wrench, and exhaust clamps.
• Most replacements complete without cutting or welding; allow time for disassembly of access panels.

Who is this for: This HQPASFY exhaust tailpipe is aimed at RV owners, service technicians, and fleet maintainers who operate Cummins Onan QG 5500/6500/7000 or Marquis Platinum HGJAA/HGJAB generators and need a reliable OEM-style replacement for part number 155-3481-02. It suits anyone wanting to restore proper exhaust routing, reduce heat and soot risk around the generator, and avoid premature failures from rusted or cracked stock piping. The product includes a 36-month warranty and customer support for fitment or installation questions.
