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




:banana:

 

I was going to get Blitz tommorow (finally got the money), but now seeing this i like it a lot especially with the price you got, any sound clips , (i know you just got it), ?

 

with the 30 awhp kit, are any cats kept in the exhaust or all they all eliminated?

 

is that an oval tip?!

 

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!

 

from the catback

 

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?

 

The whole exhaust system will be catless, the helix downpipe gets rid of 2 cats, plus the catback will get rid of the 3rd cat

 

i mean downpipe up pipe helix combo will remove 2 cats
