Sounds really good. Just out of curiosity, did you consider the other oem exhaust mod (4 perforated pipes)? I'm torn between the two and would really like your opinion.

I think the ACM sound is what I want 70% of the time, but scared it's too loud the 30%. How is it with windows up?

Thanks for the most comprehensive review yet btw
