  • help w/ exhaust PLEASE!

    I need help. I am at my wits end. start from the beginning. I purchased cat back system from 4wd, which did not fit at all. I spent 2 days trying, including taking out one out. I ended up bring my TJ 2.5L to a Monroe near by and they had to fabricate something in order to make it work. The flang that bolts to the cat is abit smaller so it wont line up right. So it sounds like a sick lawn mower. My next thing is that i think of is to bring it back to Monroe have them weld it to the cat. But I dont want to do that. is there any type high temp goop/sealant that will help seal it. I am very frustrated. So in all the damn exhaust cost me little over $600. No autopart stores around carried anytype of cat back system. SHOCKED! Please some one help me?

    if it didn't fit from 4wdh then why didn't you either return it, maybe there was something wrong with it from the manufacturer (i really don't see that happening. Other than that there is really no reason why it shouldn't fit. Also what "didn't fit" alittle more info would be helpful. As for some sealant there really isn't anything that i have found that actually works. Welding is ALWAYS allot better than clamping. i say get it welded. Or call customer service. Pics would be helpful too

      I used Muffler mender from victor. On a exaust crack. It worked for about a hour. Terriable stuff.

        Are you the original owner of the Jeep? If not it may have been an aftermarket cat.
        Why dont you want to weld it in? Once you clamp it witha muffler clamp, youre going to have to cut it to get it apart anyway.

          i agree with the first reply. if it didn't fit u should have contacted 4wd, they would have made it right. Now that its installed its non returnable and your stuck with a empty wallet and a exhaust leak.

            Like was mentioned before once you have clamped it, it will be a pain in the arse to get back apart without cutting. If you are able to get it apart you can weld a piece of pipe that is the correct size onto the cat, cut the pipe between the cat and the muffler to fit and clamp it onto the piece of pipe that you added to the cat. You need to make sure that the two pieces of pipe that you are clamping are good and straight with no dents, otherwise you will end up with some leakage. Hope this helps...
