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.
