I think most people here are trying to get close to a Porsche Cup Car sound as opposed to a motorcycle. I would argue most of these exhausts sound more similar to a Porsche Cup Car, which is as “Porsche” as you can get.

Haven't decided but just went something different. I loved the sound of the GMG. I just want a different looking tip or use stock tips.

We're finishing up the final edits for the video. I'm going to work on finding some smartphone video footage in the meantime.

iPE does offer race headers with cat-byass for those who take their GT3's/RS/R to the track.

Contact me directly if you'd like to learn more.

Anybody consider installing an actual factory 991 cup muffler and factory side delete (see pic) for real cup sound and durability? I'm looking into this with PMNA.. Likely will bolt right in. I was still running the original muffler on my 997.2 Cup after 6 racing seasons! Understood initial cost will be higher than aftermarket and may not be blingy enough for some.. Not judging )

thats exactly what ours does! Open valves completely when wanted, closed when wanted. No warranty issues, and by far the best quality on the market! We have 991.1/2 available now!

All the center muffler bypass systems do zero(maybe a smidge)for performance gains, they just save a little weight, , make the car sound better and are the cheapest route. Long tube headers with valved side muffler delete pipes are proven to make power(dundon and Fabspeed,+-30 to 40hp) and save a lot more weight and sound amazing, yes, they are a little more money but totally worth it. If you go with Fabspeed LTH's you will be happy, my car is there now getting the exhaust, cage and xpel wrap.

Hi Doug, unless you're going to add an electronic intercept of some sort and control the valves outside of the factory system, they will close between 2000-3000 rpm regardless of the state of the button (open or closed). This is due to the factory ensuring the valves are closed to prevent issues with drone.

There are electronic intercepts available, but quite honestly we like the factory implementation of the valves, they open with increasing load on the engine to keep the engine safe and performance optimized and close where there would be annoying drone (highway cruising etc...)

If you're looking for more volume, more power and less weight our 991 Street Header systems with valved side deletes is a great way to go. The Race system is even better...

I received mine the other day and I have to say they look fantastic. This is not my first Bypass but very impressed by how light but also how large the tubes are. It is an interesting design and one needs to see them in person. I am anxious to put them on next week. I also like the size of the tips. They are 4 inches wide( left to right, per se) and 4.5 inches North to South- this I like very much and with the extended tips they are going to stand/stick out- sort to speak.
