How stinky does it get w/out cats on our cars?

 

Not at all.... and when you do smell it due to the wind blowing/ car in garage/ or backing up with windows down is not a bad smell. is more like unburned fuel.

 

I have 200 cell metallic substrate cats on my LT setup. On initial startup, you'll still gag from the gas fumes. I can only guess that the car will smell of gas fumes all the time if you go catless. Once it warms up, the cats are working and the smell goes away.

 

that depends on how gassy your car is

 

i'm catless also and i seem to have the smell inside the cabin after i go WOT... i'm wondering if that's normal seeing how everything should be going out the back of the car...

 

I have full stock exhaust and after a bit of spirited driving it smells like there is a gas mister in the air ducts spraying gas vapor in my face. Love it. Probably broke something haha..

 

It's a pretty good smell, IMHO. Smells like horsepower.

 

It's pretty bad as I'm finding out now...

 

LOL! +63 yup smells like power!

I'm catless. The worst is the cold start since its pumping more gas to warm up. Other than that, it's not that bad. I just feel sorry for the cars behind you once you go WOT.
