Especially for NON-PSE owners, has anyone installed a fabspeed or any other brand X-pipe on their 991.2?

Any coments on the sound? or soundclips?

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.

Yes, what i am looking for, is for someone with just the x-pipe and not the full kit of sport cats and headers

anyone with this setup on a 991.2?

did you Get a nice sound improvement or nothing important?

John@Fabspeed

I do have someone running just that X-Pipe that i'm sure would be happy to chat with you. PM heading your way

Working on finding someone running this exact combination for you, wish our system was more friendly to searching purchased product combinations haha.

In 991.2 with PSE, the center muffler is bypassed when in Sport. Is it right to assume that a X-pipe is not going to do much?

John@Fabspeed

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.

Any sound clips of just the x-pipe installed available yet?

Bumping this thread with a question to Alec@Fabspeed, hopefully you can help ... how does a base/stock 991.2 Carrera with PSE in Sport mode compare in sound to a non PSE car with your X-pipe only in Sport mode?

Thanks in advance!

Interested as well in feedback.

John@Fabspeed

In comparison, a base 991.2 with PSE with valves open should be slightly louder than a base 991.2 Non-PSE with our Center Muffler Bypass X-Pipe in sport mode. A base 991.2 w/PSE valves closed, will be quieter than our Center Muffler Bypass on a Non-PSE 991.2.

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
