The biatch is heavy, but if I really wanted light, I would of gone for a nice single setup...
Except air flow does not work that way. Every time it is squeezed down due to a crush bend it slows down in velocity & adds more turbulence. Repeat this process for every crush bend. Then double it for having 2 pipes. It adds up very quickly!
Crush bending is a cheap way to build exhaust and you get cheap results.

Airflow actually speeds up at the crush bend. (Bernoulli???)
