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.

 

We have concluded our 991.2 GT3 exhaust design and have a some video to share which highlights the results. We found the OEM exhaust in standard mode was pretty weak, so we set out to improve this aspect of the exhaust in our design. Standard (non sport) mode utilizes a small diameter pipe and most aftermarket exhausts use a sharp 90 degree bend into the main pipe, way back near the muffler. We found this stifles the sound in standard mode, so we brought the small pipe much further out, close to the tips and created an elongated 30 degree angle transition, effectively tripling the size of the outlet orifice that dumps into the main tube. This dramatically increased the sound level in standard mode, which is a huge plus. For the main pipe, we employed an oversized "X" design for Hi Flow and to fully merge the two banks for superior sound quality. Our tips are 102mm diameter (same as OEM) with a brushed polished finish and are cut to the exact same specification as OEM and located/positioned identically to OEM. They look great and appear right for the car. In the end, we feel that we have achieved a unique exhaust design that promises to reward 991.2 GT3 owners with a quality product and an epic aural experience. This system sounded fantastic! Our exhaust systems are hand made in the USA with proper materials and are warrantied for life for the original owner. We will also be offering a substantial discount for the first 10 systems ordered by forum members.

 

Oversized "X" design provides exceptional flow and full blending of the exhaust paths for superior sound characteristics




Here is a shot of the elongated bypass tubes located close to the tips to deliver increased sound in standard mode. The elongated design triples the opening size to the main pipe, so that when in standard mode the car has a dramatically improved sound.



The tips are placed and sized exactly as OEM.

 

Great work as always John! I know it's been years - I hope all is well.

 

Sounds great! What is considered a substantial discount for forum members?

 

Thanks so much, this one really came out great! I hope all is well with you, too!

 

Forum rules do not allow pricing here, I will PM you. I think you will really like the forum intro price on the first 10 systems ordered....

 

I think I only need one system. Haha! Jk! Thank you, I’ll wait for your PM

 

And now for our 70mm X-Pipe with valved side muffler delete pipes!

 

New SpeedTech 991.2 GT3 RS Weissach pack development car. Stay tuned for updated development video.

 

Great work indeed!

 

Thank you. We have an exciting new version very close to release, it is being developed on the new yellow car.
