Excellent Magnaflow quality in my experience. Fitted to a 2003 Dakota CC with a manual transmission 3.9 liter V6 engine and due to its short length was quite noisy. I'm told I can be heard a block away from the outside, but inside it's not annoying until hard acceleration at 3,000 rpm, after which there's a less-than-pleasant hum. At 48 it suits my driving style in the country with minimal highway driving. If I had a normal working hour, I would choose a longer model, similar to the standard length.
