The t1r 70EM Sparrow is the one that has the best gains the one jdm yard has in stock is the 63mm sparrow.
I had the apexi n1 on my car, it was loud and droned a fair bit, didn't do much for the butt dyno it was almost as loud as my straight pipe but it had 100x the drone haha. Nice looking piece but that's about all it's good for a cheap exhaust. HoweverI saw your one for sale looks like a custom one with a apexi muffler.

Hey guys which exhaust would you say is best for performance and sound?
j's racing 60rs or 70rs.
I want a nice sound but not overly loud/too much drone.
..?
Or should i be looking at something like a fujitsubo exhaust?

I'm pretty sure this has been covered too lol but..
Single = best gains
70mm = best gains
the 60rs shows "some" gains nothing special. But it's quiet and sounds nice.
70RS is good power abit louder and drones abit more.
