I hate obnoxious exhausts on anything. I also love a tasteful exhaust on just about anything. I agree it's all about consideration. I did a lot of research before getting an exhaust to be sure it was a) legal b) non offensive. If everyone did the same none of us would have these problems. Unfortunately, not everyone operates with regard for others.
I listened to lots of youtube videos while deciding.
Injen was too expensive.
Steeda was too loud. (and having Steeda parts on a Mazda might make some poor Mustanger's head explode)
Racing Beat had the right combination of tone, low volume, style and price.
