IMHO this is the right balance. For a car that'll mostly be used on public roads, I'll want a unique exhaust note, but at a volume that will not bother myself (or others).Oh it was great! (for what I want).
Just starting up, there is a notable presence to it. That open valve CLEARLY demonstrates that this is just not a regular corolla from the inside. But am I going to annoy my neighbors (I live in townhomes) every day when I go to work? Not even close. Will they know it's different then a standard corolla if they are outside when I am leaving? Yes.
