Complete aluminized steel exhaust tailpipe kit for KV and QG 2500/2800 generators. 90-degree bend, 1-1/4" O.D., up to 25" length. Includes tube, hanger clamp, and clamp.
The Cummins Onan 155-2325 is a complete exhaust tailpipe kit for the KV MicroLite, QG 2500 LP, QG 2800, and QG 2800 EVAP generator series — the entire QG 2500/2800 family. The 90-degree tube attaches to the generator muffler outlet with 1 inch of clearance below the generator, then runs to the RV sidewall exit.
The tube is 16-gauge aluminized steel for corrosion and heat resistance, and is designed to accommodate installations from 18 to 25 inches — it can be trimmed to the correct length for your specific installation. The included vibration-isolated hanger clamp reduces exhaust pipe stress and dampens vibration transmission into the RV structure. For runs longer than 25 inches, or where the pipe requires support at an intermediate point, an additional hanger clamp (155-2174) may be needed.
Exhaust tube, vibration-isolated hanger clamp, pipe clamp, and Instruction Sheet G-63 included — everything needed for a complete tailpipe installation
Tube accommodates installations from 18 to 25 inches — trim to length as needed to fit your RV's generator-to-sidewall distance
The included hanger clamp uses a vibration-isolated design to reduce exhaust pipe stress and dampen vibration and noise transmission into the RV structure
Aluminized steel construction provides corrosion and heat resistance for long service life in the under-RV exhaust environment
This kit handles exhaust runs from 18 to 25 inches. If the distance from your generator muffler outlet to the RV sidewall exit exceeds 25 inches, this kit alone will not reach — you will need an additional extension. Measure your installation before ordering. The tube can be trimmed shorter but cannot be extended beyond 25 inches without adding a separate extension section.

Backed by a 90-day limited manufacturer's warranty against defects in materials and workmanship. Using non-OEM exhaust parts voids Cummins Onan warranty coverage and transfers liability for resulting damage or injury to the installer.
