When you say exhaust smell, do you mean straight exhaust, or perhaps unburned fuel?

Adding a catalytic converter will not stop the smell of the exhaust, but perhaps a better tune on the car might.

A Cat does chemical reaktions, HC is the most smelling part I know sofar and a Cat should split that.
I was told that the standard smell on exhaust gas will be significant reduced , as the cat is on working temperatur.
Unburned gasoline will not be effected.

What you need is a fuel fragrance. Click here: https://www.powerpluslubricants.com/...ragrances.html One of my favorites is the bubble gum flavor.

Once again, are you smelling a lean or too rich gas smell, or raw gasoline in itself?

Do your eyes water when the car is at idle?

I ask the questions I do to narrow down exactly what you are smelling, this way we can then assist you in resolving the issue.

I think you may have answered your own question Austria Cobra!

As long as you have made these determinations, I would throw caution to the wind and just go for it — if I were you. Based on your knowledge, if you put two or more of those on each bank and then use the proper fuel fragrances, that Patrick has already pointed you at, you should be good to go!

Personally, I think the "Reefer Madness" would be an excellent choice, with potential fringe benefits.

Hi,
At first I thought you were joking with these scents, but if 2 say it, there must be something to it
I will give it a try and look for something I can get in Europe.

Actually I am waiting for engine adjustment, but it smells like all V8 gas engines, all the same exhaust smell on FFr, SPF, all other Cobras. I do not smell special things like gas or eyes ar burning. If I lay down to the end of the pipe and stay there for minutes, it will of course or I am dead

Want to figure out the chemical Part, the technical part, will the 200 cell cat change something ? Normal cats of course do it, but I do not finde infos on sport cats stand alone.

Too much fuel over a period of time will cause a catalytic convertor to clog/fail. Fix your fueling problem!

X2, and it really does not matter whether it is a cobra, or a Fiesta , if you have an engine that is not properly tuned, nothing will fix your problem. Get the car tuned properly, then see if you experience the same issues, if so, you are done, if not, you can take the next step. However, and I do mean HOWEVER, if you have excessive emissions, where the smell is so over powering, adding a catalytic converter or fuel scents to your gas tank, will not fix the problem, only mask it. This is why I asked what I did above, trying to get to the root cause of the issue at hand. So far, your responses seem to be skating around answering them with any certainty, as you may not be technically oriented enough to give a proper answer...If that is the case, then best to take a step back, save your money, get the car tuned, then come back to us if the issues are still persisting.

I know guys! this not something new.

on my SPF it is adjusted best, 12L/100km, came in with over 30! from US.
runs perfect
but after 1minute of run, the exhaust smell takes all of the room, clothings, outside
this not anything new to V8 without exhaust treatment.

I am asking, what does a 200 cell cat do better on that.

Uhhh, I don't know about that. You get pulled over in a Cobra for mild misbehavior and your car is reeking of weed I think you're probably in for an all-around bad day.

Your car does not need a catalytic converter, it needs to be properly tuned. Usually it's a lean, or in the case, very lean condition that causes the smell and your eyes to water/burn. A decent tune up, and a retune of your carb should fix the issue. Or, the carb could have a bit of dirt in it, blocking off, say the air idle circuit, or a jet blocked, or bad needle valve. Have you pulled the plugs to see what they show?
