Does anyone have a Dynomax cat back on their truck? If so how does it sound and do you like it.

 

I have one on my hemi, I have the ultra flow, it's one muffler with two 2 and half inlets and out lets, it has a cross flow design, I't's not that loud, and it woke up the performance but did not do any thing for the mileage, if you cut out the y pipe and run the tail pipes out on the left side behind the rear wheal the old 5.4 3v should wake up to a mild yawn..
