The exhaust upgrade to the mufflers with the biggest transition (most quiet valves closed, loudest sound level valves open) is going to be our center muffler bypass pipe. As shown is our lovely diagrams (great job Mike Spock!) this is because the valves open flow of the factory side mufflers is Less restrictive on sound than the factory center muffler, and the valves closed flow of the factory side mufflers is More restrictive on sound than the factory center muffler

I have previously run SOUL PP race headers on my GT4 and sport cats on my 991.2 C2S Cab. I enjoyed those so much that I kept pushing John to get an early set of the SOUL valved SMB's for my new GT3RS. I think I ended up with the first production setup and installed them over Thanksgiving weekend.
This product like the others that I have purchased from SOUL is top notch quality. The ship time was fast and the packaging was great. The finish of the products is very nice and clean. The customer service is second to none, which anyone who has worked with John will attest to as well. It doesn't get better than this.
I am no mechanic by any means, but have installed a couple Porsche exhausts over the years. I would rate this job as a 4/10 in the difficulty range. All combined it took me a solid 5-6 hours solo to install it. It was very straightforward, and everything matched up perfectly.
The sound of this setup is just about perfect for me. I would rate the stock exhaust at a 6/10 in terms of the loudness that I personally desire at full throttle. The SMB's took it to a 8.5/10. They made the tone slightly deeper, but really kept the exotic sound of the stock car. I can't notice any drone with valves open or closed. In retrospect, I probably would have gone with the non valved SMB's given that I press the PSE button first thing after I start the car, and this car isn't a DD for me. I think I could easily have a phone call on my way home from work with the PSE on with no issues.
For me this modification fulfilled my desires of maintaining the stock exhaust quality but making it louder while dumping some weight and heat soak from the rear of the car. I really don't think you can beat the combined quality, value, and customer service that the SOUL products provide.

Anyone know how long the stock center muffler on a .2 might last with Side Muffler Bypass? Planning on only 3-4 track days a year...5 at most.
Also anyone dyno Side Muffler Bypass Pipes? I dont want to lose torque for street use.

I have ordered the CMB and hope to have ti delivered by next week.
I will put up some really nice before & afters for everyone to compare
Furthermore, i would like to add that John at SOUL is is a gentleman. In my dealings thus far his customer service is and attention (ie- replying to emails fast etc) is refreshing.
I don't know about everyone else, but it's not just the product that matters. We want nice prompt service too at a fair price without the "Luxury Car Tax".
As car guys, when we get an idea in our head that we want a mod, etc, we want it now! Haha. And contacting a shop / retailer etc, we want to have the product ordered / on the way ASAP so we don't loose that momentum of the idea in our heads. [i am like this anyway]
John has been really diligent in replying to emails and keeping me updated etc. And even went out of his way to help me with ordering the seat angle adjusters and package them into the same shipment for me with the CMB at no extra cost.
Will start a new thread when the CMB is installed guys! And also the seat angle adjusters. + I just ordered the Pepita Houndstooth Inserts for my LWB seats! Will also do a nice picture set once they are in!
