Drilled a hole in the muffler,I do it on all cars to let the water out,they say it can lay at the bottom of the cataletic converter and freez during the winter,crack the honeycomb cat and then you need a cat.well,15k miles now i drilled the holes and what did i find,a whole lot of water running out,enough that it was still running out when i got back with my camera !.
Weather it makes a difference or not i dont want the water laying in the system. (rivers side of the car)....there was a puddle on the ground and the ground is rocks ! ...ALOT of water !.....give it a try.

Oops, wrong thread.

I meant to ask you, if you're worried about water pooling in your cat, why aren't you drilling a hole in your cat?

Cant hurt to get it out of the muffler and i dont want to touch the cat LOL

interesting

didnt know that..
i thought people drilled holes in the muffler to make it like rice loud?

Not me this is my daily driver.... I have a vette for that LOL

so.. you drilled your vette's muffler too? :doh:

better put some jb weld on that hole now.

The cats run too hot for water to build up inside, additionally, the vertical nature of the primary cat doesn't allow water to collect in it. The secondary is still very close to the motor and any airborne moisture that might make it's way that far up the exhaust would be expelled from the heat and pushed out into the cold, restrictive, and apparently collective stock muffler. The OEM muffler is the heaviest and most over engineered part of this car lol.

so.. you drilled your vette's muffler too? :doh:


LOL No not yet,but i will.
I dont know if the cats have water in them or how it all works...but all the cars i have ownd have water in the muffler at the lowest point from the cat.never fails.

Heres the vette,---> http://s262.photobucket.com/albums/ii111/victory-rc/ZO6%20NEW/

Most of that water in the mufflers is just sitting in the insulation out of the flow of the exhaust. It's not really hurting anything except maybe over quite a few years of exposure to the elements it'll rust out and sound the same as a hole drilled in it :P Nice vette though.

Yea,i dont think its a big deal but ,it lets out the water:yawn:

I see your in florida,wish i was there.

That's sexy. have you tried just running it on the headers. A friend of mine was putting a aftermarket true dual exhaust on. We were curious to see how loud it was.... never again. No joke the idle was as loud as my car at redline WOT. The vette under WOT was just ridiculous. My ears hurt afterwards.

No,I'm not removing the exhaust. Lol. Maybe drill a hole in it. Lol

If drilling holes in your exhaust was good for the muffler/car, it would come with holes in it already.

If drilling holes in your exhaust was good for the muffler/car, it would come with holes in it already.

There were cars that had that hole years ago,that's where the idea started.but with the laws for emissions now you must have a "sealed system".it can't be any good to have a cup of water floating around in the muffler ,that is about how much came out.

If it can't be good, how do you know it is bad?

i have to say...that is the worst idea i have ever heard...make that heard in a while...how does water get in your exhaust?the only water in your exhaust would just be condensation from sitting out over night. it wouldn't be that much, then, as soon as you fire up the car and start driving it around, the hot exhaust gases will heat the exhaust up to above boiling temperatures and send all the water out as steam.

now, lets just say, hypothetically that water does enter the exhaust system overnight, and can freeze the cat and make it fail or whatever, the problem is that your exhaust system is pretty flat and level, nearly parallel to the ground, so the water isn't going to drain out unless you park on a slope so that the gravity drains the water down. but wait, if that were the case anyway, then all the water would just drain back and settle in the muffler anyway, and not in the cat, and thus just be waiting to get expelled when the exhaust gas heats it up anyway.

i'm sorry, but as far as the realm of useless car mods goes, this one is pretty useless, relatively harmless, but useless. also, the reason why you don't have holes in your exhaust system is so that you don't have exhaust gases entering the passenger cabin and inebriating the drivers.

so please, reconsider this, and then plug those holes up with some mighty putty or something.

If it can't be good, how do you know it is bad?..... Re-read post #1 it says. The reason.

Tell me who "they" are that say this can happen and I'll almost consider that a reason. You're purely speculating and have zero proof of this happening (that I've seen yet). I'd suggest reading Drax's post above.

okay, i just asked my mom, and my uncle, they are both over 60, and grew up on a farm in montana, just south of canada (so probably just as cold as CT), and this is a completely foreign concept dude. how many beers did it take to come up with this idea?

i'm not trying to attack you, but this to me is an idiotic little idea. i'm actually from a corvette owning family myself, we have a 1995 corvette, a 2001 corvette, and my uncle has a 1978 silver anniversary corvette, but non of them have holes drilled in the mufflers.

Lol,your cars cat converter makes the water

Lol,your cars cat converter makes the water
Wow...

LMAO, wow

If the cat makes the water then why don't you drill a hole near it?

Well,if you and I were sitting at the table drinking beer,I would take a bet about water being in the muffler of new cars with a cat. And if you did as I did we would find :H2o leaking out of the hole. Lol. Where's my beer nowm. Pay up. Lol. Older cars did not have stainless exhaust systems like newer cars and rusted out

LMAO, wow

If the cat makes the water then why don't you drill a hole near it?

A cat costs 500 to 1000 bucks on a new car,depends. And I think your more likely to find water "after" it more then unde,I never drilled a converter and won't for the price,r

Well if the water is after it, then it is not affecting the cat now is it

and the reason why exhaust systems rust out is because rapid heating and cooling when driving in wet conditions, where the hot exhaust gas heats up the exhaust system, and when driving in the rain, sleet and snow and salt (depends on state procedure etc), the cold water or snow or whatever that splashes the OUTSIDE of the exhaust causes it to rapidly cool for a moment, and the salt also eats at it, causing oxidation and rust on the OUTSIDE of the exhaust system.

now, lets go back to your theory that your catalytic convertor creates water, even if it did, again, the residual heat from the exhaust gas would continue to keep water droplets from forming until it was dried out. now, the condesation of water that forms inside they exhaust, would be pure water (practically distilled) and the only impurities would be remnants of burnt carbon from your exhaust gases.

how can you be smart enough to have a job that allows you to afford a corvette and a tc but dumb enough to think drilling a hole in your exhaust is a good idea?
give me your corvette before you drill any holes in her.

:no:

No............

water is a product of burning hydro-carbons........

go retake chemistry......

This is basic information here ,come on,---> http://www.catalyticconverter.org/faq/index.htm

What do you know, they said nothing about water getting into it.

I just retired from the navy last year,20 years ,in charge of a DSRV.

WHAT DO YOU DO ?

What do you know, they said nothing about water getting into it.

who said water "gets in" ?..... its from the cat.

OHK.... ITS BEEN FUN. google "muffler weep holes" turns out they have a name. good job !

I dont see your point, you drilled the hole so water cant get to the cat from muffler but the cat makes water. So how are you solving anything?

hahaha.. :rofl: you think being in the Navy for that long is gonna impress anyone here? well sure doesn't for me.

i just read every post in this thread and i only have to say one thing.

draxcaliber FTW! lmao

I can only say LOCK THIS THREAD.

:no:

No............

http://unreasonablefaith.com/wp-content/uploads/2009/06/jesus-baby-cry-caption.jpg

not in anyones defense but yes water is a product of burning hydro-carbons, correct?

taken from "how stuff works"

"Catalytic converters are designed to reduce all three:

Carbon monoxide (CO) is a poisonous gas that is colorless and odorless.
Hydrocarbons or volatile organic compounds (VOCs) are a major component of smog produced mostly from evaporated, unburned .fuel.
Nitrogen oxides (NO and NO2, together called NOx) are a contributor to smog and acid rain, which also causes irritation to human mucus membranes."

considering the fact that the only way a cat could do this is by heating them up tot he point when they burn.

there for the catalytic converter burns hydrocarbons which in theory would create water? correct?

i like how you tried to prove him wrong by proving him right.

now im not jumping on anyones side but i just think for someone to say something like you did should really know what they are talking about.

the catalytic converter does create water. and actually in a perfect world a car would only give off O2 and H2O (oxygen and water) but unfortunately its not a perfect world and there are other things that a car creates due to combustion (CO2, CO, NOx etc)

thats why when you start your car (sometimes) after its been sitting for a while you'll see a little bit of water shoot out when you go to move (or rev the engine) because water has been collected in your exhaust system due to the Cat doing its job.

while this does sound like a stupid thing to do to your exhaust i can see where hes coming from on doing it.

would i? no because from there you have a point where rust can form due to BARE metal being exposed to the elements.

the reason why the stock muffler and stainless steel exhaust systems are made to not rust are because of A. a coating on it to protect the bare metal under it and B. the qualities of the metal.

while in some cases the elements will "eat away" at the exhaust causing it to rust over a long period of time, the fastest way to induce rust is to expose the metal (ie. drilling a hole in the muffler)

so while as much as you guys would like to flame him for doing this, its not really necessary to attack him. and im surprised that some of the people that posted in this thread did in such a way.

he was trying to protect his exhaust system in a reasonable way.

the water that was in his muffler could have quite possibly sped up the process of rust formation in the muffler (who knows if its coated inside and thats a very common reason why mufflers rust from the INSIDE out).

if you dont believe that, go work at a shop that does a lot of exhaust work.

oh and learn a thing or 2 about chemstry and how car parts work. they are made to do certain tasks for a reason (ie cats burning hydro carbons to form water because water is better for nature then hydro carbon).

just wanted to throw my insite here because everyone else feels it necessary to do so also. prove me wrong nobodys perfect and i've been wrong before.

man everything turns into a argument in this forum good lord...

im not arguing

im not arguing

Contradictory statements ftw! lol I love this place hehe.

I yield and apologize. I like learning new things and definitely have here and thank you for that. Drilling a hole in the muffler....still seems like a bad idea to me, whatever. A shop doing an inspection upon seeing this, should fail you. Do I care whether or not they do? Heck no.

But your parts, your car. Do what you want.

2C8H18 + 25 O2 ---> 18 H2O + 16 CO2
(gasoline combustion)

we were both right lol sort of :lalala:

yeah, while i admit i was wrong, your exhaust only needs 1 hole in it, and that is the tail pipe.

Just throw a few packets of silica gel in the tail pipe and call it a day before we get too scientific over this lol

lol a bi-product of the combustion process is H20 believe it or not and yes it can collect in your exhaust system. When i had a angled muffle on my tc, it used to shoot water out on start-up daily! this is neither a bad idea or a great idea but it couldnt hurt, it might prolong the life of the muffler (not the cat) if your living in CT

I think we're done here.
