I installed gutted cats, and now my exhaust smells really bad.
I have to drive with my windows closed.
I double checked installation and could not find any exhaust leak.

But it smells really bad in the cabin at idle with window open.

Anybody had an issue with this?

 

It is probally just some oils and ish, should burn off with time.

 

I just helped a friend of mine install testpipes on his mustang, it will smell for a while. no worries.

 

hmmm....
I hope you guys are right.

It was smoking somewhat at 1st, but that was the oil burning off.
How long do you think before the smells goes away?
I cant enjoy the deep sound with the windows closed.

lol

 

well, black smoke comes out when you rev right? and it smells real strong right? you shouldnt worry thats what happens when you have no cats, there is nothing there to filter you exaust.

 

no black smoke

 

SS--- What the Cats do is burn any raw fuel that isnt burned in the Chambers by super heating it. Ur smelling un burned fuel and to a certain extent, any residue thats left. Give it time ---U cant have the best of both worlds

 

Cars without cat convertors stink.

That is normal.

 

thats the reason why you wont pass a smog

 

you just removed your emissions control... of course its going to smell...

 

 

 

it should get less worse after a week or two, but the smell really nvr goes away. It gives me the same kind of headache hangovers give me

 

yeah, i had an mr2spyder with 2zz swap with cat removed, the smell never really went away, i never dropped my top after the swap and always rolled up the window when stopped or i'd smelled like gas when i got home or where ever i was going

 

when i had my test pipes. i smelled like gas everywhere i went.Some ladies really dont like that... so i went with HFC and the problem was solved.

 

When I got my test pipes I never paid attention to it. If it smells I just dont notice it

 

what did you expect when your car doesn't clean the exhaust gases?

 

don't worry my stock Z is smelly at WOT

 

Actualy, my mechanic ran a test and he said i will still pass the inspection.

I would not be 100% sure about it.


I hate driving with windows closed.

 

I like the smell.....sniff sniff.
