Anyone ever run one? Wondering how loud it'd be compared to a 3.5" Flowmaster with a 3.5" case.

The Flowmaster is pretty quiet at highway speeds, but I think the case size is a bit small, being the same size as the pipe.

what are you wanting to put it on? ive had two on a 350 and one on my dmax. those things are gonna be louder than the flows for sure.... i think theyre only rated at a 3 or4 db reduction

The truck in my sig. Maybe I'll just put a larger case Flowmaster on it.
