I have a 2003 Mustang GT and i'm looking for a muffler to make it really loud. The loudest muffler that i know of is the Flowmaster Super 10's. Is there any that are louder than that?
Additional info:
everything is stock

run the pypes m-80s, or just straight pipe it.

If you want loud, go with no cats and straight pipe.

Also go ahead and expect to upset your neighbors, co-workers, and every policeman you drive by.

Personally I have an O/R Xpipe with Flowmaster Super 40s. That's more than loud enough for me. Youtube has tons of videos, just search some different types.

I currently have borlas on there so what i really want to do is get an o/r H pipe but it wouldnt pass emissions so thats why i'm strictly looking for a loud muffler, that way i can still stay legal

you want extremely loud?? get QTP cutouts!! or PIPE's cutouts from American muscle... the cutouts are awesome because they are loud whenever you want your baby to scream!! if your not going to have over 450 horsepower then there is no need for a fancy exhaust" long-tube headers" or xpipe hpipe ...

you want loud?? then listen to the you-tube cutouts... awesome sound...
