There's not a ton of options for the second-gen cars actually. Your choices:

GReddy MX
HKS Hiper
Tanabe Super Racing Medalion
Tanabe Super Hyper Medalion

The GReddy and Hyper Medalion are more reasonable sounding, the HKS and Racing Medalion are really loud.

For reference as to what my personal definition of the terms "loud" and "not loud" see this thread: https://www.honda-acura.net/forums/s...threadid=35132
