Question Mandrel vs Wrinkle Bent?

So I am in the market for a new custom aftermarket exhaust, and the vendor doesn't have what I want with Mandrel Bent pipes, only Wrinkle Bent.

Would the wrinkle bend restrict my airflow to negate the efficiency and horsepower gains from purchasing the exhaust in the first place?

Comparison: http://www.truckexhaustkits.com/prod...es/35_zoom.jpg

A Google search seems to indicate that the difference is negligible on vehicles that aren't producing a ton of power.
