Thanks for sharing your experience/knowledges guys.
As I already purchased Fabspeed headers, I'm going to install them along with O2 spacers.
Also thinking about getting a COBB tune. Once I get them installed, maybe I'll try to take some sound clips so people can compare with PSE+Xpipe setup.

 

Anyone have videos to post, to hear how the different exhaust set-ups sound?

 

You can find mine in the forum under my posts. However, it's not close to 50% of
real life sound

 

Pse & awe.

 

Here's my comparison of PSE vs. Cargraphic's X-pipe. I also have a couple of short videos of my AWE SwitchPath system I installed on my GTS (coming soon). Unfortunately, I didn't take a shot before the install, but the sound variations are still apparent and were taken with the same camera.

 

Very nice comparo. honestly surprised how aggressive the x pipe was with all the guggles and pops without sounding drowny. I generally replace the frontish and mid section ish of all cars I get with a proper x pipe and optimally sized diameter piping

Other when sound did it make any performance gain, I always noticed much better throttle response and better mid range and top end.

 

Outstanding video.

Is there much in the way of cabin resonance with valves open at low rpm with the Cargraphic X-pipe?

Also, I second the question about power gains. Looks like dynos were done...

Thanks!

 

Thanks VTGT. It really was super aggressive, but it makes sense since an x-pipe on a 911 essentially removes the main center muffler that acts as a sound buffer in Sport (or valves open) mode.

In terms of performance or throttle response, I really didn't notice a difference. Mid-range to top-end power *may* have improved slightly, but it's hard to tell for me. I don't think it was enough to justify an x-pipe strictly for performance gains, but thankfully, I wasn't looking for that.

Thanks!

Yes, there's a bit of resonance with the valves open at low RPM. The AWE system has the same exact issue, but at a different powerband. With both systems, you can really avoid any cabin resonance/drone by being out of the particular RPM range that causes the issues.

In terms of dynos, EAS was great and threw in 3 dyno pulls for a nominal charge, but only after we installed the x-pipe. I ignored a before/after dyno idea since I didn't care about performance gains.

I'm also going to post another video comparing the AWE SwitchPath with my other two setups.

 

Cargraphic TS X-Pipe sounds amazing with PSE.
I'm thinking i should've got the Cargraphic TS X-Pipe instead of the Fabspeed headers/sport cats...

 

That is the video I am looking forward to, want to decide on AWE vs. PSE. Thanks Christophosphorus!
