So I am about to install the FVD sport exhaust on a 911S and have a few questions. I don't want to lose the interior noise from the sound symposer - is it connected to the exhaust in any way? I know it's noise coming from the intake, but wanted to make sure there isn't some vacuum tubing connecting the symposer to the exhaust somehow.

Also, is it recommended to heat wrap or coat the exhaust? I've just recently heard of this and did a google search with mixed results. Any input is appreciated!

No you wont lose the sound from the sound symposer. My FVD xpipe is wrapped and somehow still managed to melt the vacuum line that came with it. Doesn't matter to me since I would never close the valves anyway. Iam curious what did you receive with your xpipe for the valves to work?

 

That's really odd... my FVD x-pipe isn't wrapped and I have no issues with the vacuum line. I posted on the other forum how the line needs to be routed and installed... check it out. Having said that, I wish FVD would wrap the line like Porsche does instead of the foil/tape.

 

Well I didn't order the center muffler bypass x-pipe, I ordered the sport muffler exhaust with valves (http://www.fvd.de/us/en/Porsche-0/99..._and_Tips.html). The system is still in the box at the shop, but I will let you know what else they sent along with the exhaust.
