Thread: exhaust leak

  1. #1

    Default exhaust leak

    hey guys, what the cheapest way to fix an exhaust leak?
    is it to just find a friend with a welder and have him seal it up?
    its about 8 inches before my muffler where the hanger is attached, real small hole, but i can hear the spattering.
    would you even consider fixing it or to just ignore it?

    It really depends on why it's leaking.
    Is the pipe cracking or is it rusted out?
    If it's just a crack then the welder would probably be best but if you've got corrosion then you'll be better off replacing the pipe.
    I'm anal I'd fix it.

    Back in the day when I was broke I was known to cut a tin can in half and wrap it around the pipe and use a couple of old coat hangers to wire wrap it around the pipe. I will say it never lasted very long but it kept me from getting a loud exhaust ticket!!! LOL

    i honestly think its more due to corrosion :/
    but a whole pipe? yikes! i dont think its worth that much money... or is it?

    How much would an excessive noise ticket cost? I've been to Corpus quite a few times so I know the Police there can be a little troublesome at times when regarding vehicle violations.
    You might be able to get away with just replacing a section but you wont know untill you get in there and get a look at it.
    The aluminium can method has worked briefly for me a time or two I just get tired of redoing the job, Muffler tape is cheap enough at the auto parts store too, but sooner or later ya gotta fix it the right way. Either way do something before you attract the wrong attantion and get a fine to go along with the repair cost.

    well it is only a tiny corroded hole it seems, is does not seem to be any louder than normal, or would i not be able to hear that difference? i definitely dont think im worried about any "excessive" noise, although your right i hate cops here lol

    I would just get down there with a welder and just cover up that hole. Is it on the factory pipe?

    If you can grind the metal to remove the rust, then find someone with a stick (arc) welder and have them weld it. Mig welders don't work well outdoors if that is where it will be done, due to the shielding gas getting blown away from the weld point. Yes, they can still weld if the gas is not there but it will spatter and the weld will be very ugly.

    Have you tried looking up a reputable muffler shop and asking them about it? You might be able to get a referral from someone on here or just research it yourself. They may be able to do a cheap fix until you can replace the pipe. Just ensure they're reputable. Otherwise they may try selling you the whole shop for a small problem. I wouldn't let it go though. Particularly if it's due to corrosion, it's not going to get better as the months go on.
