flo-pro muffler?

I just did the dpf/cat delete with a SCT and a 4" downpipe back system from flo-pro. The system came with a muffler. Truck runs MUCH better.

It is very quiet though. I was thinking of maybe deleting the muffler but was not sure how it would sound. I don't want anything obnoxious or that is going to get me pulled over by the cops all the time but this thing is no louder than stock. I would like to be able to hear it, but not overwheliming if that makes sense.

Does anyone know if you can buy the muffler delete pipe for the Flo-Pro 4" system? I bought mine with the muffler and was considering trying it without the muffler.

I think they sound better w/ a muffler. At WOT they sound better w/o muffler but daily driving and echoing off buildings is pretty obnoxious w/o the muffler.

I can see both sides..but for 40 bucks (or whatever they cost) if you don't like it, slap that muffler back on and sell the straight pipe LOL
