Then we have to account for weight discrepancies in the car and heck, don't forget the weight of the driver! What octane fuel was in the car? Tank full or empty? You could go on forever finding discrepancies that need adjustment to simulate absolute equality.
Seriously, I'm not trying to argue with you. I understand the desire to use correction factors as an "equalizer". It's just that at the end of the day, it provides room for someone to say "but".

Back on topic.
I think the article is written like a sales pitch press release rather than an honest review.
As far as cabin noise goes, I couldn't hear my tyres or pebbles in the wheel wells. Just a howling Fast Intentions cat-back as I ran up the mountain at WOT in 3rd gear before downshifting for a switchback. I don't think Dynamat would have helped.
