That used to be my exact setup, for about 2 1/2 years. I honestly loved the sound. Sounds even better than straight pipe I thought...I often thought it sounded very close to straight pipe, but without that edge that you get with it. Trust me it sounds really good.I have a 2007 5.9 currently with a muffler delete and I am looking looking for it to be a little louder. Anyone know how it would sound with an aero 4040 and no cat??
I ended taking mine off as I just spent too much time in the truck, and hauling a heavy load or high speeds on the highway I would get some nasty drone.
The 4040 is more of a resonator...one look at it and you will see. It's not cheap either.:thumbsup:
