I recently bought my truck and just before I bought it they replaced the catalytic converter. It sounded great at first but now when you accelerate it makes a weird exhaust noise. It also does it when you start it. It is not affecting my gas mileage or anything but it is annoying. Is there something that they could have missed? Does it have more than one to it? Anything is helpful.
