I have a Apexi N1 before, but just sold it because it's too loud.
but I just purchsed my hardtop, so I am thinking to get a single exhaust again.

I am interested in J's N1, Spugen Ti single V2 or some other single with angle muffler in cheap (around $500).

I actuly like the Spugen Ti V2, but looks it's hard to find a used.

give me you opinion plz.

 

I've heard the J's N1 and it was loud. Very loud. If you didn't like the Apexi, then you probably won't like the J's.

I say go for the Amuse R1 Titan. I really liked the sounds of it. It resonated in the cabin between 3000-4000 RPM, but I think you'll get that from any single. The sound itself was very nice, though.

 

Do a search on T1R

 

I installed the Spugen TI on Thursday last week and have had no issues. I figure if I can still hear the music with the exhaust and the top down on the freeway I am good to go. So far so good.
