Apexi WS2 is DEAD silent, except ricer buzz @ 2.5k
An Apexi WS2 exhaust was installed on my LS and it's completely silent. It doesn't sound like there are any leaks. It feels like it flows properly, I just don't get any noise out of it. I know this exhaust is quieter than most exhausts, but the sound level on mine is equivalent to stock.

The setup is:
Tri-Y headers
six inches of 2.5" pipe
fourteen inches of 2" pipe
back to 2.5" for the resonator and all the way back to the muffler.

Is it possible that the random section of reduced pipe is affecting the volume or flow of the exhaust system?

It doesn't sound like stock and at the same time its not supposed to be loud. It will get louder as time goes on. But if you have no cat, it will buzz.
WS2's are quieter than stock 06+ Si exhausts and louder than a GSR/LS exhaust. Kind of close to a stock ITR exhaust....but the ITR exhaust sounds better. WAY better, jerky.
