Gotta replace rusted exhaust on truck gonna buy magnaflow highflow cats. Problem is it says its not air tube kit adaptable. Picture shows two holes between the 2 cats, and on stock, one is air tube other is o2. Does that mean i cannot hook up stock air tube? Want to run true duals but cannot find a way to do it without throwing code or making it go into limp mode.

THANKS

I believe the new CATS do not need the pre-heating the like the old ones. The air tubes added oxygen to the CATS, which help to heat them up quicker to the proper operating temps.
Someone correct me if I'm wrong, but the air tubes can just be left to dump air, and not throw a code?

 

Thanks. I thought that might be the case. But if I don' plug line off how loud will air coming out be

 

You would hear the puffing of air coming out of the tube, but it isn't super loud.
Lots of people simply remove the air pump. You can get a new shorter belt to bypass the pump.

 

Is that second hole for the EGR connection tube?
I remember one of my older trucks had the EGR connection tube feeding from the CAT.


I could be way off; but I just figured I would mention it.
