Default Mandrel bent exhaust tubing vs. not

It sounds like it isn't that easy to find exhaust shops that work with mandrel bent tubing. Since the typical bends restrict the flow somewhat, would it make sense to go up a tubing size or is the restriction minimal enough that it does't really matter. Any match whizzes out there ever figure this out?

Thanks, Doug

Unless you're turbocharged or running fairly large pipe, a crush-bent exhaust system will cause minimal losses. Not even worth worrying about, IMO, especially if the exhaust shop knows what they're doing.

i have a custom crush bent catback exaust system. there aren't very many bends in the piping so i wouldn't be too worried with mandrel bending exaust systems.
