Why Manufacturers Place Crush Bent Exhaust Piping?

[saadi123]

If mandrel bent exhaust tubing is much better then why do car manufacturers install crush bent exhaust system at the first place? I mean is there any advantage of crush bent tubing over mandrel bent?

 

[PocketRocket]

cheaper for mass production and time of producing each one is shorter

Maybe cheaper to crush than to mandrel bend.

People tend to change to aftermarket exhaust systems too.. Most to most, they keep it stock till the warrantee expires.. So car manufacturers lazy to mandrel-bend it, coz most likely it will be changed..
