zero...


zilch...


nada...

BTW, this was not gutted by me or anyone else. for whatever reason, the internals, cracked, broke apart and blew out the tailpipe.

the other one had what appeared to be about 1/2 of the substrate or ceramic brick remaining intact...

so I guess I know for sure what that cloud of smoke was that I saw shoot out of my tailpipe the other day...

later,

Well, thats a perfect example of the old expression "blow it out your tubes"...

Nice show & tell pictures!.

 

Put a straight pipe through it and be done with it.If you leave it like it is it will cuase turbulance in your exhaust kinda defeats the purpose of a free flow exhaust.

I would send those pictures to magnaflow.I thought a converter had to last for a certain amount of time and or miles. that one looks like new on the outside and is empty already.

 

Now that's what I call a high flow cat...

PEacE..................

Holy Snikes....Whats the HP rating on those Cats...LOL!

 

i know that sucks but thats just funny to me.

 

Looks like mine



But to be honest all the C12 and C16 I run in my truck peob didn't help them

 

Bummer Chris (+ you too Don)

Been seeing a lot of these pic's lately, many actually.

I got to say over the yrs, we have read TONS of Post about defective and or unhappy customers re: aftermarket exhuast here on F-150. One has to wonder if they're just overpriced crap ??? (Oh here we go)

BUT WHEN WAS THE LAST TIME YOU SAW A STOCK CAT
GO BAD IN A FEW MONTHS ????
Or a stock Muffler shoot off, or rust out, constant blown header gaskets, totally hollow cats, I DON'T KNOW MAN, you know what they say, if it looks like Schitt, smells like Schitt, and taste like schitt, then it must be

What was it my L Brothers (and Cecil Pit Pals) were saying about their full L exhuast systems at Cecil, they're just multi thousand dollar sound systems that add no performance. AMOF one was freshly tuned with it, and ran slower.

I'll continue to stay stock thank you, and believe I can run 10's with it someday if and when I go built motor and MAJOR N20 HP

EDIT We need spell check around here for us dumb people,
hehehehehe

 

Considering the warranty on exhausts mandated by the EPA, like never.

 

The only mod I have on my exhaust is a Borla cat back and so far so good.

 

If you don't mind post a soundclip with the cats gutted and let us know what your dyno looks like. I wouldn't mind my truck being a bit louder.

The LT's, high flows, and bassani just aren't loud enough for me....

 

Since someone asked... My '91 Exploder I dusted a stock cat on it... It was the damndest thing, there are so many rattles, knocks and what not, I didn't hear the faint 'marbles in a can sound'... It just kept getting s l o w er... finally, I could only do 60 mph wide open, and I could not hold it up hill... The mileage was way over 120k miles - the odometer had stopped and I had to get that replaced for inspection - I'm guessing 150k...

 

150K compared to a few months is quite a diff.
AMOF that happen to me too in a Beretta GT, the SOB wouldn't
even get up to speed it was sooooo clogged. Had @55k on it when it happen, but they did find a bad sensor they claimed caused the cat to go bad.

What we're seeing with these aftermarket exhuast seems to be more of a "built quality" issue. We've all read posts of aftermarket mufflers rusting out, cats holling out, etc....
It seems for such a high price, they just don't seem to last nearly as well as the factory exhuast ??? I would still like to make mine a tad louder someday though, just not sure which way I want to go ? Maybe I'll just weld in an electric operated bypass and have the option to be as quiet as I want, OR AS LOUD
