Sounds like a racecar... I did this to my Mazdaspeed 3 a couple of years ago, but it was STRAIGHT piped, I mean no cats no reso no muffler, needless to say, it was cool for a week cause my car sounded like it was ripped off the track, but... I ended up throwing down for an aftermarket catback about a month later. It was just too much, highway drone was TERRIBLE, around town was okay but like I said, got old fast.
Though, the first rev when we finished the downpipe and removed the cats in doing so, completing the straight pipe setup did set off a car alarm across my neighborhood... lol
