That's the problem with crush-bent or non-mandrel bent pipes...
Is it going to restrict flow?
Of course it is...
If it a restriction to power?
It depends...
If you run one size bigger, it should be okay.
Non-turbos run 2.5" as a rule-of-thumb, so if that's 3" crush-bent pipe, you should be okay.
If that's a 2.5" crush-bent pipe, then I'd say it's restricting power.
