Sorry, I pasted the wrong link. I fixed that. And I was responding to kroy's opinion that the ARK exhaust is loud.

 

^ In terms of super loudness, I don't think it's in the loudest tier. But Ark is on the loud side IMO.

The only complaint I have is the low drone at 1800RPM. Like when you're cruising on surface streets going 50. Hums fairly loud.

It's not really that bad though. and likely more so my personal preference. For reference, I thought the stock IPL exhaust droned too loud in those ranges as well.

I think the sweet spot for me is 2800+. 2800-3200 range is my favorite. The tone lightens up from a deep drone and you get this purr. Makes me smile every time I hear it.
