No Cats Smell

Hi Guys,

I am intrigued by the guys that claim no cats = big smell. My lawn mower and snow blower do not smell.
The pre-1974 cars never had cats and they don't smell. Today's cars do a more efficient job of burning gas so what am I missing?????

Thanks
Ken

Your lawn mower doesn't smell?

I think your nose is busted man.

No cats = smells like unburned fuel. With a proper tune, it shouldn't be an issue.

My former Mustang Cobra was catless with LTs and had a "proper tune" from SCT and it definitely smelled like gas. My wife even asked if my Corvette "would smell like the Mustang did" when I bought it.

I didn't say it wouldn't smell, I said it shouldn't be an issue. As in it should be tolerable.

It matters what your tolerance level is... even running at unsafe lean levels a catless car will smell of raw fuel.

If you make the car leaner than stoich, it'll stop smelling like unburned fuel and start stinking like NOx. I think I actually prefer a slightly rich smell to a lean smell.

No cats and a tune here on my 01Z. Smells is definitely stronger but far from intolerable. I'd be really surprised if it offended someone.

I have lt's,no cats and an "alright tune"..the smell doesn't bother me (maybe im use to it) but it bothers just about everyone that comes near my car lol..hopefully when I finish getting the tune on point, I can lessen the gas smell some.
