Also have Speedtech 2.5 "quiet" exhaust. I was disappointed at first until I had my buddy do a drive by. It's certainly not quiet when standing outside when the engine is in the upper revs so don't let the inside the cabin sound fool you .

Yep 100 cell cats . I run w fellas that have NA engines w secondary mufflers removed so I'm the shy quiet one. Since I use the car for long distance I find the cabin noise at the sweet spot of tolerable/noisy .

Anyone on here have a Unobtainium Welding system? Curious what you all think as it's a 3" system that's supposed to completely eliminate drone due to the helmholtz resonators.

The helmholtz resonators really do work to eliminate the drone. I've had my exhaust both with and without the helmholtz resonators so I was able to experience the drone and the lack of drone on the exhaust same system. I have a write-up on 6speed outlining the before and after the helmholtz resonator addition.

I've had an Unobtainium Welding exhaust for 6 years now, and it's fantastic. As 32krazy! mentioned, build quality is exceptional. The sound can be tailored to your preference with a combination of mufflers, tips, and cats, but the x-pipe design sounds awesome in general.

What do you like about it ?
Considering this system, watched the youtube videos, certainly sounds great. Curious what others think about Soul for their 996 TT...
