Exhaust bend question

I recently had exhaust installed on my 2017 3.5L and happeend to look under the truck the other day and notice a u shaped bend in the exhaust just before the exit tubes. Any idea if this 'should' be there, or why its there period? Seems counter intuitive to creating a less-restrictive setup. Apologies if this is common knowledge, I dont know much about exhaust.

Picture below

Thanks for any advice.

 

That is a kink bend. By-product of bending tubing without a mandrel bender.

 

It's a special bend used with Catbatch exhaust.

 

Thanks! Does it have a big effect on performance?

 

Nothing lost or gained. Just there to ease installation..

 

Make sense. Appreciate the help

 

Won’t effect anything

 

Technically, at the flow levels of his truck, no it won't. On a more preformance oriented setup, it would be leaving gains to be had.
