home brew exhaust idea..

I keep seeing people dong their own exhausts using a magnaflow muffler, they fit good and sound good, but just going off videos they seem like they would be loud enough to get annoying over time…

so poking around online I came across a similar dimension muffler that isn’t just straight through, I want more grumble, but still gotta be able to hear the stereo. ha

the muffler im thinkin about is a flo pro 4415XX

they are dirt cheap, seem like would be a bit quieter than the magnaflow and have no fiberglass packing to burn out..

anyone with any experience have any input? good idea? bad idea? waste of time?
