With how restrictive the stock exhaust system appears to be small piping towards the back of the car, I just don't see the factory downpipes being an issue.
Modern catalytic converters flow so much better than they did 20, 30 years ago.
No doubt I agree, however things flow better with no cats or less restrictive cats typically. Especially when adding more boost in the picture - would be nice to see some type of performance gain from the parts
