SpeedTech 991.2 GT3 Exhaust Development Thread
SpeedTech is very fortunate to have a new 2019 Porsche 991.2 GT3 "RS" model left in our care for exhaust design and testing! Today was the start of our journey to create an epic performing and sounding GT3 exhaust. We have some new, innovative ideas that we wish to employ for the first time in this GT3 design and are very excited to implement them on this model. We are cautiously optimistic that we can achieve exceptionally positive results. I will update this thread as we get further along and into the testing phase of this project. Our schedule calls for a tested design and finished product available around the end of February....We understand this is a crowded market, but feel we have something that will differentiate itself a bit from the field, making it a very worthy alternative.
Pictured is the OEM center muffler removed for examination and subsequent jig construction. https://cimg9.ibsrv.net/gimg/rennlis...ca3f177e66.jpg https://cimg4.ibsrv.net/gimg/rennlis...b12774a5fe.jpg https://cimg6.ibsrv.net/gimg/rennlis...1ad7bfd4c1.jpg |
I think the market wants a valved side muffler delete for weight reduction paired with a center bypass to get that loud RSR sound with the ability to tone it down with the valves. |
What would be really trick and I bet sell really well would be : Side Muffler Deletes that are valved that go into a center muffler that is a 2 part piece where the valves close and route the exhaust through the top of the side muffler delete into the top of the center muffler for a muffler type of sound...nice, louder than stock but no drone. Then open the valves on the side muffler deletes to route the exhaust through the bottom of the center muffler that is actually a straight through center pipe design. |

Doesn't JCR have a setup you can piece together just as you described? And it's full titanium .

Don't mean to be negative but I can count approximately 120 other firms that make exhausts. As such, it's truly hard to believe that another one can add anything significant.

John,
I am really looking forward to your GT3 exhaust!(Especially titanium model which very few are making, even less in a true x-pipe design). Having had dozens of popular and 'best sounding' exhausts on my exotic cars for years and most recently going SpeedTech on a .2 4S, I am a true believer . Your passion and love for these cars shows in your exhausts, they are beautifully made and simply sound amazing! |

If you come up with something that you can guarantee deletes the 1500-3500rpm drone/booming with the valves open - you have a customer. That particular offer doesn't seem to exist on the market yet...

Well, according even to (a couple of) manufacturers of those, they drone with valves open in that rev range . I do not want the valves in play at all - I really do not like the transition they create...
