ElPolloDiablo Posted January 20, 2022 Share Posted January 20, 2022 Dear All, I would like to replace my Nikko high-mount muffler with another sports muffler that I ran into. I'm not terribly clumsy, but I can't seem to get the linkpipe off the collector. Sprayed several times with IMAL, tapped it with a screwdriver and hammer, but alas. He seems to be coming a little, but not enough. And yes, the screw is loose. Any other tips before the whole neighborhood ends up in a madhouse because of me banging the hammer? Thanks!

Member Contributer tbzep Posted January 20, 2022 Member Contributer Share Posted January 20, 2022 Dead blow hammers are a lot quieter and don't damage soft surfaces as much. They are good for taking out frustrations without annoying the neighbors. 😉 Let the penetrant work a few days and just keep working it. Link to comment Share on other sites More sharing options...
Member Contributer bmart Posted January 20, 2022 Member Contributer Share Posted January 20, 2022 I use a rubber strap (oil) wrench on mine when it gets stubborn. Link to comment Share on other sites More sharing options...

Member Contributer Cogswell Posted January 20, 2022 Member Contributer Share Posted January 20, 2022 To bmart's point, I think he's implying that you use the strap wrench to rotate the pipe to break the corrosion. Great idea. You don't want to bang on it too much and put dents in it - that will only make it worse. You could also break the clamp tabs off, but you probably won't be re-using it anyway. On re-assembly with your new pipe, some copper or better yet nickel anti-seize can go a long way towards preventing the issue in the future. I remove mine once a season to prevent the pieces from becoming too friendly. Link to comment Share on other sites More sharing options...
Member Contributer DannoXYZ Posted January 20, 2022 Member Contributer Share Posted January 20, 2022 Here's how to spread that joint slightly: 1. place coin/washer in slot between the clamp-ears 2. insert bolt from threaded side 3. screw in bolt so it pushes on coin/washer 4. add 2-3 turns more and it'll spread out joint (reverse of clamping down). 5. spray PB-blaster into gap created by expanding, let sit overnight 6. twist and pull and it should come off.

Member Contributer BusyLittleShop Posted January 20, 2022 Member Contributer Share Posted January 20, 2022 You'll find the job is easier if you first heat up the engine to operating temp and then tackle the joint... heat will expand the grip on the clamp... the hotter the better...

ElPolloDiablo Posted January 21, 2022 Author Share Posted January 21, 2022 It worked. With two guys. It was like giving birth and cost a lot of sweat. But he came off with a lot of patience and physical strength! Link to comment Share on other sites More sharing options...
