Catback without Muffler.

[jpford4x4]

I have a 6.0 with the MBRP 4" Cat Back with Muffler and was wondering if someone that has removed the Muffler and ran the delete pipe could tell me if there was any more or less exhaust noise? Could you explain the difference to what noise you hear comming out the tail pipe. I have the Muffler in place and its welded so I donot want to cut it off and ad the delete pipe if there is no difference in sound. Thanks, jfordRattler.

There is a difference...I did the same thing and she wasnt loud enough for me so I cut the muffler off and added a pipe cat back and the turbo screams and I mean screams...she is much more louder and Im very happy about what I did...Trust me you'll like it....Oh but one lil thing...when goin down the highway there is a drone inside the cab...but it's worth it.
