How loud is the Helix catback on a catless system? Or what is the most comparable catback in terms of noise to the Helix?

pardon my ignorance, but how is it a catback exhaust system if it doesn't have a cat? or is the name "catback exhaust" meaning from the cat back?

Damn i sound like such a newbie!

See Exhaust Diagram on Matt Randolph's site. Catback system starts at the flange after the third and last catalytic converter, and includes the muffler.

but doesnt the helix downpipe get rid of both the cats after the turbo? so if one had all of the helix exhaust parts there would be no cats remaining?
