I would appreciate your thoughts on this statement. Do you feel better low end performance? Any drone? Thanks!

Yeah, I saw the same before purchase but figured it was kind of marketing hype. I haven't seen any catback exhausts with real performance gains. I will say it doesn't feel any slower in the low end, but I can't feel much of a difference. Haven't dynod it yet. Will be installing the full exhaust when it's ready.
There is absolutely zero drone. A nice coast down growl at about 2k RPM...just exaggerates the car's natural tone at that speed.
