Cummins 155-2449 Exhaust Resonator Automotive Specialty Parts

This was probably the best money I've spent on my RV. Anybody who has had one knows about the loud generator exhaust and the issue with sleeping at night especially if your running the AC. But this investment changed it for the better. It fit fairly easy and was a breeze to install. When I fired up my generator it was a Kodak moment because I couldn't stop smiling. The little silencer did exactly what it was designed to do. I've never heard such a quiet generator on an RV. It's a very good investment because of the reduced noise level and it also made the generator a little better on fuel consumption and that's definitely a big benefit. So if your trying to make your generator a “lil” more neighbor friendly and quieter or just need good durable muffler that'll withstand tests of time, then look no further, this is the best value for your money.
