#1542, "RE: Quiet Exhaust for GST" In response to In response to 4
If you really want a good exhaust, get the Apex'i N1. The sound is incredible out of this setup and it is very quiet at idle, compared to many others, and has a sweet hum on the highway cruising. But if you are hard on the gas, this little monster definitely makes some noise.
Another bonus. If you ever want to get a downpipe, you can order an apex'i n1 downpipe that will bolt directly up to that catback.
