Hey guys,
IPE Innotech has been hard at work researching and developing their full catless valvetronic exhaust system for the 991 for quite a few months now. IPE Innotech is world renouned for making Porsches sound very F1-ish, and they surely did not disappoint with their 991 valvetronic exhaust system. IPE's valvetronic system is manually controlled via a remote control or automatically with the throttle position sensor or RPM speed.
Here is a sound clip showcasing the 991 exhaust system ! As always, all IPE exhausts are hand crafted from 304 stainless steel, TIG welded, CNC machined along with laser cut tips with optional titanium tips.
The full system includes race headers, catless pipes, valvetronic mufflers and X pipe, tips and remote controls.
We are currently offering 15% off MSRP until the end of May!
Turn up your speakers and listen to one of the best sounding 991s yet !

Does it follow the "sport" button settings by getting louder and quieter on command?

Not to belabor your post, but just for clarification are you saying that you could add this system to a non-PSE equipped 991, order the PSE button for the center console from your Porsche dealer, and have everything wired so that the IPE valves are activated through that button (making everything look factory)?

That yellow bullet only has 415km on the odometer . . . so much for the break-in period. ![burnout](https://rennlist.com/forums/graemlins/burnout.gif)
Awesome sound, only problem is to get that F1 fly-by experience, you can't be driving. Dang!
