"Spun cat" vs. high-flow cat

[Afboy143]

Hey guys,

Whats the diff. between this spin-cat cat

vs. this stock looking highflow cat

Do spin cat type cats flow better? Are they louder?

(Magnaflow type cats)

The thing that no dealer or salesman will ever tell you, is that it's the material inside the cat that determines airflow. it is a ceramic or metal mesh, that will allow the same airflow rate, no matter what...because of emmisions laws, that material has to be made in accordance with regulations, making it impossible to create a "high-flow" cat. you might as well buy the tornado.....
