I've read a number of threads about exhaust setups on the 991.1 GT3, and most have concluded roughly the same data ...
1. IPE exhaust sounds good, but quality is an issue
2. For a center muffler delete, GMG is the way to go
3. Minimal data on Armytrix, Fi, Fabspeed Longtube Headers, and Catless systems. This is the area I'm seeking info.
I'm specifically interested in the Fi exhaust, to have that high pitched scream. Loudness is great .. and I'm not afraid to have something very loud.
Since time has gone by and more owners are acquiring 991.1 GT3's, I'm hoping I can kickoff a thread that gives more feedback on some new and questionable exhaust systems.
If you're looking for an aggressive exhaust note worthy of a GT3, check out our Competition Long Tube Race Headers.
Our comprehensive system is built to optimize the Porsche 991 GT3 / GT3 RS engine’s exhaust flow for a significant power bump along with more sports car sound.
We also use premium components in the construction of our Long Tube Race Headers - T304L Stainless Steel with Burns Stainless Collectors and Helical Valves.
I see you're in King Of Prussia, which is about 25 minutes from us. Feel free to swing by sometime to check out the facility (located in Fort Washington, PA) and see where the components are fabricated!
