I bought one with the same shipment as chewy, sounds spot on mate. I suppose it all depends on what your after.
I would go for the 60rs if you was looking for a track friendly exhaust, or one that can be lived with on the daily drive.
So far I'm in love with it. Quite on idle, deep tone on cruising And as it should opens up in vtec.
If anything I'm hoping it does get abit louder once iv racked up a few miles. I did the same as you went for the 60 as the 70 was too loud. But I had the spoon n1 and one with a unsilence b-pipe before that, and that was naughty. This is much more tame. But then it can always be changed hehe.
