Split Air Pipe on Aftermarket Cat??
Do I need to run the split air pipe into my 3" Catco hi-flow catalytic converter in order to have a good shot at passing emissions?
I made sure to get one with an inlet pipe, but will the cat alone be sufficient to get me through smog tests?
FYI: I have all my factory emissions stuff functional, and its a S4 TII. It will just have a custom turbo back exhaust.

"Catco" I've never heard of them. Is it a rotary specific Cat? most cats are not designed for a rotaries high exhaust temps and burn up.
I believe the Bonez unit is used without the split air pipe. Don't know about yours.

The split air tube (the small diameter one - about the thickness of a pencil) is used to open the 5th and 6th intake ports. It has nothing to do with emission controls.

Nah I just got the Bonez TurboFlow (highflow cat and dp) and it uses the split air pipe. It comes with a piece of hightemp hose and 2 clamps to attach it. Was pretty easy to install.

The shop that welded all my stuff together welded a split air pipe onto it, so it should be good and solid.
However, the exhaust kind of smells weird, and when I tried to get it inspected after having the exhaust done, it failed ONLY by low-speed Hydrocarbons.
The guys said I need to "break in" the cat, since it's brand new, to pass.
Does this sound right??

Yeah, see I wouldn't think it would take long for the cat to be emissions ready.
The exhaust fumes still smell kind of strong though, kind of like a sweet smell and burning rubber, is that normal?
