My guess... not on the same Dyno, not on the same car, not the same parameters, ect.
EDIT: I honestly never looked at Fabspeed, but now that I have I can say the you're probably going to see a difference with the additional plumbing that comes with the soul. Fabspeed looks to be a cut and attach to existing vs. souls replace it all. There has to be some magic in the plumbing. But all the above reasons still apply!

Yeah I looked carefully at any changes in piping to induce laminar flow or diameter changes but couldn't tell, albeit just from pictures. Maybe SOUL can pitch in here. Is anyone from fabspeed on this forum as well?

I bought the Soul just this week... so my decision process was more of a See it, Like it, Buy it type thing with Zero investigation into other options. Now that I see the option, I'm glad I went the way I did for my car equipped with PSE that I wanted to maintain.
Can you describe the sound? I wanted to go suspension mod, but may just do an aggressive street alignment and just an exhaust. How much has the sound amplified? Was the install relatively easy? I'm on the same boat, want to maintain PSE.
Also, have you noticed an increase in power and its delivery?

I believe @HooosierDaddy and I are at similar stages with the SOUL downpipe recently purchased but not yet installed.
I pick mine up on Wednesday and will install it soon after that.
Between the two of us there will be more info to come.
FWIW, One other thing to consider, SOUL is the only mfg. that warranties their systems for track use.
Some other systems have been known to fail; check out the Suncoast track car build.

Thank you for considering us.
Physically, our downpipe is a complete catalytic converter and downpipe solution vs a cut and bolt in catalytic converter. The downpipes primary benefits are unleashing great notes from the turbo and increasing the response of it. I'd definitely consider power a secondary benefit - and more so when paired with a tune to make use of the increased flow. Peak power is great, but always consider the entire curve as the cumulative effect of greater power gains across the RPM band leads to a better overall driving experience.
The numbers on our Sport Catalytic Converter Downpipe were provided by a third party shop, Growler Motor Labs. We like to show third party dyno results on most products as we believe you should be able to walk into a shop and get a similar result. I take the ethics of marketing seriously and do my best to show accurate information including weights, power gains, sound expectations, and time frames and I'm happy / relieved to be at SOUL as some past employer experiences made me very uncomfortable. That said, I do think Growler's numbers are on the higher side. I had another customer who dynoed with lower numbers. There is a lot at play with getting dyno numbers - the number of fans and their position, the settings on the dyno, the operator, the condition of the car, has the ecu had enough time / mileage to adjust to the modifications, weather, and much more. Our goal is to have a hub dyno in the shop as soon as possible to show our own numbers more often as well. If I'm provided dyno data of say, 3 runs from a Dynojet - I'll use the middle of the runs to show an average. On the flip side a lot of our dyno results show lower numbers than our competition, but we try to keep it real at whatever cost.

I view it as a base to build on with the added benefit of improved sound to satisfy my performance itch.
Sure it will changed the performance of the vehicle, but each vehicle will (with all things being the same) experience different results. Close enough to say "Average" gains are XXX, but you've got to be realistic in knowing there are variables. The audible difference is a known factor and my sole (soul) reason for the change.
As for it being the base to build on... tune's, cat back exhaust, intakes, ect. will all net better results with this part.

I think Soul (aka - performance drug dealer) does this on purpose... it's kinda like crack, once you get the downpipe your hooked and will keep coming back for more!

Just an FYI:
You can guess which company we prefer 'round these parts.
(Oh, and a final bit: Soul was founded by ex-Fabspeed folks. If that doesn't speak volumes, I don't know what would.)
Just an FYI:
- Fabspeed had an employee on this forum at one point. After some amateurish, ham-fingered posts, he flat-out refused to identify himself as an employee in his sig after multiple Mod requests. At one point, I even called Fabspeed and asked to speak to the employee in question, who had (to that point) been with that company for a number of years, to explain the reasoning. This employee never responded to any of those queries, and soon after them, he stopped participating.
- Soul Performance, on the other hand, has been nothing but professional, helpful, deferential, and transparent on this forum.

Thank you, Mike. I don't often talk about it publicly, but I am a former Marketing Manager at Fabspeed and I did do the media of / launch their 718 suite in my time there. This gives me valuable insight into many different configurations from multiple companies. While FS is direct competition, I do speak honestly and fairly when it comes to evaluations of any product as it pertains to each individuals goals and needs.
