So i've decided that i want to either get an o/r x or a high flow catted x.

i'm wondering are high flow cats as orderless as normal catalytic converters, or do they smell as an o/r mid pipe would.

also will an catless 4.6 smell as bad as a catless carborated car?

I would guess somewhere in the middle. And I would guess a catless carbed car would smell more.

I can almost guarantee a catless carbed car would smell more. My friend had both his Mustangs catless and they did have a smell to them but mainly under WOT. However my friend has an old Camaro which smells under most regular driving conditions. I've never ridden in a car behind my car but I know it probably has a catless carb smell to it.

curious of why someone wonders if it smells. it sounds better point blank.
prolly cause he is concerned that going down the road if everyone behind him thinks his ****in car stinks. i dont blame him. i would'nt wanna look in my rear view and see a family covering their nose with their shirts cause my cat's are gone....anywho unless you have some sort of exhaust leak it wont be that bad.

What color smoke?
Blue- burning oil
White- burning coolant
Black- rich fuel mixture
Orange- wtf?

^lmfao @ orange-wtf? sometimes if it sits for a while it smokes just from water vapors (steam). if the smoke just dissipates and doesnt blow a trail behind you than that's prolly all that is. mine will do that especially when it's below 60 deg. or so.
