991.2 X-PIPE
#2
I'm also interested what people think of their 991.1 installs as well. Here's what Fabspeed is recommending - any sound clips of this setup would be greatly appreciated.

With the valves open, the PSE center muffler is bypassed internally not externally so there is still a little bit of muffling of residual sound. However, in our opinion due to how straight through that bypass is it wasn't worth a replacement of the center muffler itself. On the PSE cars, unrestricting upstream from the center muffler via the cats offers the best improvement in performance and maintains the variety of exhaust notes from the center muffler. It's actually pretty cool, not only do you get two different sound from having valves open vs valves closed, but Sport versus Sport Plus makes a big difference as well. In Sport mode the wastegates are open and provides a much more naturally aspirated burble/overrun and overall agression, Sport Plus the wastegates are closed and has little to no burble/overrun and less overall aggression but more turbo sound.

Here is a video of the full 991.2 Exhaust Suite:
I don't have a video of just the X-Pipe, but if anyone is local and wants to swing by for an install, I can certainly extend a package deal
