I like mine, I wish I knew what brand it was because it came with the car. Searching "bullet" doesn't really help as it's such a generic name, and who knows where that sticker came from. The resonator is definitely a Dynomax Bullet muffler, maybe that's where the sticker is from? It has a nice deep sound, not blatty or obnoxious to outsiders at all. Growing up with Mustangs I hate most 4-banger exhausts but when wife drives my car I like hearing it drive away.
As for Subaru sounds, my 65 Corvair with a boxer six, no headers, and Borlas sound just like a Subaru with aftermarket exhaust. Go figure, right?
