I just found some sound clips on YouTube.
OBX

vs.
5ABIVT's SW headers/Corsa Exhaust
https://www.youtube.com/watch?v=yfLcyPJZpS0
5ABIVT's is WAY too loud, however the OBX seems to have a very quiet sound, which would be perfect. Can't find any deep review on the OBX headers/exhaust system on here though...
Important question: does it say "OBX" on top of the tip?
Thanks!
