exhaust?
Gurglers are VM3, twin1(barely), and the autospeed truedual.
Borla may be too droning for you, I'm not sure what your tolerance level is. G2 is definitely too loud.
You may want to look into Milltek, APR, Twin2, and I'm sure there's others out there too.
Check the websites, they have sound dl's.
