Well yesterday I well my friend and I decieded it would be cool to put a straight pipe in from before the cat all the way back to the tail pipe. Well let me tell you waaaaaayyyyy to loud. I was just waiting to get pulled over. And the noise in the cab on the freeway shook my teeth. So with the help of you guys here on the board i went down to the local big rig shop and bought a donaldson MO85171. Its right at 40 inches or so. What a night and day difference. Left the cat out just installed the muffler. It is still lound but only when you get on it. And the sound at freeway speeds id great. Thanks to everyone with their post that helped me pick the right muffler.
