After a few weeks wait my G Pipe and Catbypass have arrived from fabspeed. Excited to get them on tomorrow. Have to say that this is the 3rd product I have gotten from fabspeed (I have a 991.1 C4) and they have been great to work with. The G pipe is so nice I sort of feel guilty putting it on the car!

Warning: your car will be very loud with the g pipe/bypass combo.

The better, but more complex and expensive choice, are headers and a RarlyL8 muffler.

I loved my 964 with that setup, you won't be disappointed.

Loud? I've got a 1968 396/375 BBC with electric QTP Bypass Valves that I run all the time.
Serious window rattle

I've run our flat 6's with open headers & it still doesn't come close.

But then again I'm probably half deaf already from all the metal concerts in my teens.

Very Loud for sure..I only use the G pipe only when I go to Cars & Coffee loooking forward to Porsche fest in August at Summit Point for the autocross and Maybe a DE, Going with the G pipe for sure..You hear the Turbo spool up.. Luv it

Spent the weekend driving the car around. I am really happy. It is a little quieter than I expected but that is offset by a huge amount of pops and gurgles.

A big bonus like heliolps2 mentioned is that you can really hear the turbo spool. I wasn't expecting this to happen and it great!

awesome. Glad you like it!

Just goes to prove how each set of ears are different.
