    Has any one used those inserts that go into strait pipes to muffle the exhaust on a truck I have a 98 ch dump truck. Its just way to loud But dont have enough room between the cab and bed to put mufflers and no room under cab for resonater. I found some inserts on Iowa 80 that fit into a five inch pipe. can any one tell me how well this will reduce the noise and how much it will affect my power and will it hurt the engine

    Just not enough room on ch to put resonater under cab its a tight fit to get your hands between frame and exhaust pipe ( I like a quiet truck )

    I have 5" dual straights with inserts on two of my trucks. The inserts take alittle of the bark out of the exhaust but by no means makes it quiet

    I got mine from 4-states. They're not real easy to install, they fit tight.
