I've done similar in the past. :oops:

haha...when I was younger and much less wise about my first car I probably would have considered it, lol. These days Autozone sells outer sleeves as well as inner diameter/outer diameter connectors to patch two pieces together. Much better option and most are <$3 iirc.

My brother has done this twice now. Fell off once, and then just slapped on a new can. I guess it works, but I question why he'd do that when we know a guy who would most likely be willing to weld it for him if he'd ask nicely.

I had asked why he didn't ask the guy to do it for him, and he basically said his welds suck. I'm thinking, well, it's your fracking exhaust, not suspension work. It just has to hold air in there. I'd rather have an ugly weld than a tin can.

open header or bust

actually anybody have a catless side exit exhaust, so you spray exhaust at cars beside you?

Ugh, talk about taking all the fun out of driving. I get a pounding headache after too long in a car with a loud-ass exhaust like that.

Tuned pipes can sound good, glasspacks can sound good, but fart cans and open headers ALWAYS sound like utter crap.

lol, on my dads lil '89 Chevy S10 farm truck the muffler fell off. so as a crafty 16y/o, I literally stuck a coffee can on the end of the straight header and hung it with bailing wire. Sounded so ghetto, yet so awesome. Didnt muffle much though.

Years ago, a buddy drove a beater (while fixing up his classic Mustang), and it had the rotting exhaust disease. Every time it would blow a hole in the pipe, he'd get a soup (or similar) can, cut the bottom off it, cut vertically through the tin with some snips, then wrap it around the pipe, clamp it with a couple stainless steel hose clamps, and then seal it with some exhaust pipe tape. He told me once that about half the exhaust was held together that way! :eek:

Best I saw were beer cans with the ends cut off being used as sleeves on an exhaust. Wish I had pictures...

similar to this

I generall just keep cutting it back and removing sections of it past the break till i end up with open manifolds and no piping, my truck right now is running manifolds with about 3-4' of pipe from each bank and no cats/mufflers, it makes the cops really happy when i have my foot into it going up a hill and it sounds like someone is firing a machine gun out of my truck, good thing i know the local cops.

Im replacing my exhaust next week just waiting for my headers to arrive.

edit spelling

Hi,
Just wanted to document my repair (as i read lots of guys on amazon/ forums saying that this type of repairs last a short time). Had 2 holes in the exhaust pipe (just before the muffler) of my old (2003) car. There is one more hole on top at same place (not visible on photo; its size being slightly smaller). Was supposed to use a small piece of aluminium can piece (or a tin can piece) to cover the hole and then apply cement over it – in my haste and excitement (LOL) to do the repair (as a neighbor, who was arriving soon from abroad, wanted to use the car), I forgot about it.
Used Visibella cement from aliexpress. Car is not used much and was not used at all (not even started) during a period of 6 days (car has been used lightly after 9 days; it was started for 5 minutes on 7th day). First cleaned the pipe with a steel wire brush and Steel kitchen utensil cleaning roll.
For 5 consecutive days, a layer of this cement was applied by finger after wetting the pipe/cement with water. 1st day – as the holes were quite big, it took some 3-4 tries to cover the hole/s. Ambient temperature – above 30-35 deg. C during the day.
Here are photos from Day 0, Day 1(24 hrs), Day 5(120 hrs), Day 15 (neighbour is using the car).
I am hoping it lasts for 5 years :) (what do you guys think?)

I've done similar "muff-o-mend" type of repairs, think more like 5 months, not 5 years. The issue is, you didn't supply anything for the patch to secure to, you could have placed a mesh there, (and held on by a clamp) to give it foundation, as is it's prone to the vibration of the engine eventually shaking it loose.

Muff o Mend , sounds like a QVC beauty product .
LOL, yea, back in the '70's, (specially in northern climes), exhaust systems took a beating and they were not stainless steel so products like that were popular, I had so much on one car it looked like I had King Tut slung to the axle..
