High Flo cats

[utm18]

Do the high flow (green cat) smell as bad as a off road pipe?
I'm currently running lethal off road H on my DD and most days the smell is terrible. Thinking of going with the high flow cats or back to stock?

It will reduce the odor but it will never be like stock unless you throw the stock cats on there.

On a side note, the smell of raw fuel and old school exhaust brings back great childhood memories. I like the smell, but that's me, I'm an old fart.

My '11 doesn't have any smells with the headers and OR H pipe. I do drive with the windows open. You might be running a tad rich.

I asked my tuner if that was the case and he said that it wasn't running rich. Idk

No, it's just the way it is when you run catless.
