I want a quiet ~3" catback for the SR. “Really” Quiet by SON standards. Think: stock G35 levels or the Borla Hush 3" catback on my friend’s tuned WRX (youtube it - they do exist). The Apexi Noir (a coated WS exhaust) isn’t the prettiest but seems to be the quietest. Is anybody running this? I’ve been told that a s13 SON runs one.
I have full Megan gear from header onward, 3" cat and type 2 catback. I’ve also tried one of those Apexi valves.
I gave the Noir all the googling it could take and I’m mostly convinced its quiet enough but I’d really like something firsthand. Appreciated!
