Is anyone running this muffler? And if so, what size did you get? They have different dimisions depending on the vehicle (3"x10", 4"x8" or standard 4"x9.5").

I've checked out FM's website and it looks like the 50 Delta Flow is a little lounder than the 50 SUV version but not as loud as the 40 series. I heard a Banks system the other day and it was louder than I'm looking for. I'm curious how this one compares to the Banks and the MBRP systems. I'm tempted to spend a little extra for the MBRP but I'm not convinced it will add that much more, if any, performance than the Flowmaster. Anyone have input?

 

I will comment on the MBRP. I felt a little more power, no difference in MPG, and I was expecting it to sound a lot louder, but overall, disappointed.

Many threads on this, but take a look at the sounds clips provided in the below link.
