Catalytic converters

[tissimo]

Ok, so my car is bone stock (minus suspension and wheels.. oh and a sweet K&N drop in!!) meaning still has the stock catalytic converters and everything.

The car smells like shit now and assume the cats are going, is there any way to revive them? or at least stop the smell, haha. I know removing them would solve the problem, but I like the quiet comfortable ride as it is..

Theres no sniffer test in FL so them actually working doesn't matter, I just want to stop the smell.

Get a high-flow cat.

Smell is usually for a reason... Contamination, wrong AFR....

No sniffer test, you can run a test pipe. I got mine for like 60 bucks from sip racing.

A few months back I had a big exhaust manifold leak, I'm sure it caused some funky afrs for a bit. Other then that all is fine, gas mileage is normal. I usually fill up at the same gas stations and has been smelling for about a month and a half.

Though about 2 months ago I did fix my BOV so it didn't leak and was flogging on the car quite a bit. Maybe the old age + the low AFRs of WOT coated it or something?

Any fix?

I prefer to fix as cheap as possible, so a new cat is out of the question. I'll just knock it out and cut out the precat if i have to, but would rather not.

Just remember about the visual check. If they look and there's no cat, uh oh.

New cat is about $100 bro...

I've heard that different gasses sometimes don't play well with some cats. Try different gas stations and see if a smelly pattern emerges.

No inspection here.

$100 wasted, I'll knock it out/cut it out before wasting money like that, lol.

I'll give it a shot.

I was mostly saying that to lewis, but it applies everywhere there is a visual safety inspection.

well if you wanna be sneaky you could alway just weld a cat covering over your test pipe

I go to a place on 44 called atlantic fuel. Its just two middle eastern guys one in the store one in the garage. When i first bought the supra I passed with an ez button taped to the dash for a horn, no tail/brake lights (TLFS issue) and i had taken my cat off and installed an hks downpipe, but hadnt gotten my test pipe yet so the exhaust was just dumping out the downpipe. My brothers 98 dakota just passed with a HUGE manifold leak, and a check engine light with like 10 trouble codes. Inspections stickers are the only business they get as their fuel is trash, and noone trusts them to work on their car, the other bay is always empty.

Thats clever! I like that!

 

[hvyman]

just punch it out and weld a tube inside so it doesnt leak.

/facepalm

I hope I'm never behind you guys in a cruise...

I know that, cause you told me that. I'm just pointing out that the visual inspection still exists, and to be careful if you are going any other place than the 2 middle eastern guys.
