Thank you to Rennlist member J.Ho for sending us his absolutely beautiful 991.2 Carrera C4S for development at Soul Performance Products! Seeing this car come off of the truck in Pennsylvania after traveling from South Carolina was VERY exciting for us! We are going to develop and test various components allowing us to provide a great product to the community that will be backed by third party dyno data and thorough video/photo comparisons. This thread will be updated as we progress. In the meantime between updates, we are eager to hear from members with any product recommendations, ideas and other thoughts.
We begin by evaluating and fixturing the stock components.
Stock catalysts: 15.85 lbs
Porsche Sport Exhaust (PSE): 22.90 lbs
OEM Tips: 3.2 lbs
Total OEM Exhaust (PSE Equipped) Weight: 41.95 lbs
The current plan is to develop and fabricate:
Tips for the OEM muffler in various styles (made in house!)
HJS HD 200 cell Sport Cats
Cat Bypass Pipes
Center Muffler Bypass X-Pipe
A track oriented straight pipe turboback exhaust - optional turn down tips
And for dessert - a GIAC ECU Flash to pair hardware and software together for maximum power gains.
In the future we hope to continue development on a proper valved center muffler as a PSE replacement. We will be updating this thread with the comparison between the Soul Performance Products offerings weights, photos, video comparisons and dynos vs. OEM so stay tuned!
