all of maxxfab's products are mandrel bent. he does not use press bent in anything, and never would. scott is meticulous about his systems and makes sure that they are the best out there.
now on the mounting point issue i do agree, none of the systems out there have extra supports to give it a secure fit, however that is easily remidied by going to a shop and having a hanger welded on.
i'm not a fan of side exits personally, but a lot of people are. i wouldn't venture so far as to say they are crap (at least not the maxxfab, the bdj is a different story) or that an exhaust shop could do it cheaper. getting mandrel bend piping is not cheap, and having it custom done can cost a lot of money.
