I agree it doesn't look the best, but seems like on all Ti systems the tight bends are done that way. Probably a cost/volume issue. Only a large manufacturer doing lots of units could afford to hydroform. From Rogue Engineering site:

Titanium Exhaust Feature Pros
Extremely lightweight (between 12-26 lbs.)
Cool sound
Unique look
Will not rust

Titanium Exhaust Feature Cons
High cost
Frequent failure rate (cracking welds and hangers)
Difficult and expensive to repair (only to have it fail again)
Difficult to control sound
Difficult to mandrel bend
