Feel free to let me know if you run into trouble. You can do it at home. Just make sure it is properly supported. Never trust a jack alone.

If you try it and run into trouble, I'll try my best to help.

You have a great night as well.

I do not trust Jack's alone. I have a few jack stands I can use of my neighbors and some big blocks of wood. A good friend of mine was underneath his travel trailer levelling it out about 5 miles out of town around 5 years ago. The trailer fell on his chest and by the time the ambulance got there it was too late he was only 50 years old. The sad thing is he wouldn't have let anyone else do what he did. Thanks for the reminder though. Often people think it can't happen to them until it does. Maybe I will go to my friends garage. The job will go faster with another set of hands. Have a great night!

Thanks. Just as an example; the V band flange clamp kit is $49.99 apiece at the local Auto parts store ( I won't name names) out of curiosity I looked at it to see if it was the same material etc as the ones I got for $7.99/ea and it was. I know parts stores have to make a little money but then normally a mechanic makes a few bucks off the parts and there's nothing wrong with that. I'm just happy that my friends dad is a mechanic and he has offered to do the job. Of course I'll pay him. Probably with the money I saved on parts, lol. I will post pics when it's done. Thanks so much.

Okay, I have not started this yet. The weather has not been the greatest rain rain and more rain. We actually have a freeze warning tonight too. I was looking at the diagrams maybe I'm looking at are wrong one but I noticed one had a T Bolt Clamp. Do I need this clamp also. I do not want to start this and I need something. Maybe that was the split converter you said one of the diagrams were. I have Friday off and weather permitting if I do not hear back from my friend I'm going to jump in and just try this myself. Thanks

The T bolts are on the V clamps. The clamps wrap around the two flanges with the donut in the middle and use a bolt to tighten down. The OE ones use a T bolt, aftermarket ones use T bolts or have welded on bolts. Both work.
No rush, been raining daily here as well, I'm thinking of buying a hovercraft to mow the lawn. LOL

Right! Well, you can ride your hovercraft out to the houseboat In building, lol. I was hoping that exhaust would have been done before my doctors appointment in NY on Wednesday but it's all good! I have an extra V clamp here if I need something I'll use my imagination, lol. Thanks

Hi,

First and most importantly, I hope everything went well for you in NY. As far as the exhaust, I know it may be some time since you get to it, but please feel free to let me know if you have questions, need help, or just to let me know how things turn out for you.

Take care,

Joe

Thanks and I definitely will. I need to get all those parts out of my entryway anyways so I'm thinking of possibly doing it myself soon. I have an 02 sensor removal tool I have the sensors cuz that one is welded to flex pipe. I have all the clamps and all brand new parts even if it takes me half a day it can't be that hard. I know I can do it I remember changing a muffler on a Renault Alliance I had back in the day! Thanks for being patient with me! NY trip went good! Next trip I hope I have an inspection and emissions appointment.

Hi,

I'm glad to hear everything went well. I'm sure you're happy to be home. LOL

I don't know if you need them, but I attached directions below for different parts of the exhaust system. I hope they help.

Take care and let me know if you have other questions.

Joe

Hello, well the hard part is over I think! What a mess. Plus jack stands and blocks of wood really can't take the place of a lift and air tools. 4 hours non-stop and tomorrow the new will go on. I just wanted to show you the mess I was working with. I'm assuming that was the hard part. I hope it was, lol.

Hi,

It doesn't look like it was in very good condition. LOL. That is the worst part because of the rusted parts and bolts. The new parts will be much easier to install.

Take your time and be careful when you're under the vehicle. Please make sure it is safely lifted.

Take care and let me know the outcome.

Thank you. Yes, I jacked it up and put pieces of wood under the front tires and jack stands on both sides underneath and then I let the jack down. You can never be too careful. Yeah I knew it was a mess. I was able to save the upstream O2 sensors. The other two welded to the pipes are getting tossed with the pipe. The guy I bought it from buys and flips cars. There's still a right way to do wrong. I know they sell different size flex pipe so I don't know why he even put it on because even with the clamps he had on there was about 1/2 in gap so it wasn't sealed anyways. Oh yeah I knew it was a mess that's why I dreaded starting it. The original V clamps were still on there. My reciprocating saw sure helped, lol. Thank you as always and I'll post more tomorrow afternoon. Have a good night!

Oh boy. So I ordered one smaller butt clamp. I can't remember which part but it's behind the catalytic converters and y oioe but the clamp just won't tighten down any further. The pipe isn't going out it's in there but the clamp just slides around a bit do instead if a 2.25 in I have a 2.0 coming.I'm going back up to my friends garage even though I'm doing it outside of the garage. There's more light outside. I'm going to have her help me hang it. It just seems there's no room under there at all now. I'm wondering if those old parts were even the right year or vehicle. This exhaust takes up every inch of length under there.I tried to hang the back before I left last night but I was tired hungry and a little frustrated over my tire going flat. Tried putting air in it the valve stem is bad so Im going to have to take it off and take it to the repair place. I worked a midnight to noon ran up there until I had to go back to work from 6pm to 9pm ran up and it was just too dark to see how in the heck I can hang the back. It's been a learning experience for sure but it looks so nice. I'll post pics when I get up there after noon I'm still at my midnight to noon shift. Maybe so shouldn't have tightened everything up so well before I tried hanging it. Thanks again.

Okay, got to untighten a few things. That's why you just put it together loosely then hang it then go back and tighten it. I know nothing about pounds of pressure for torque so I'm just going to pray I get it all right.

Done. Except for the one smaller diameter clamp I got under there and couldn't see or feel any leaks except drivers converter to y pipe. That new pipe smell though. I'll drive it fir swhile then get under there in a werk see if I csn tighten it down. It's very pretty and shiny under there. I will post pics in a few hrs omw to work.

Hi,

It looks great! Good job. As far as the smell, there are stickers and oil on several of the components to identify part numbers and prevent rust. That smell should go away.

Now for the clamp, I'm not sure how you got a 2" one on in place of a 2.25". Usually, they won't fit around the pipe. As far as tightening, just make sure nothing can move. Torque is done using a special tool called a torque wrench. Most people don't own one.

Let me know if there is anything I can do to help. Otherwise, great job.

Take care of yourself.

I'm not sure I can get that 2.0 clamp on when it gets here either. The 2.25 band clamp aka butt clamp aka coupler clamp just seems big and it's sliding around. The pipes are together real good but when I started the vehicle and crawled back under it that was the only place I could feel air coming out of and I'm pretty sure it was a 2 25 like the other. It just will not tighten down enough so it doesn't move around. Maybe the manufacturer sent the wrong size? I'm not sure I have a 2.0 coming maybe I should have ordered a different 2.25. Thanks. It was not as hard as it seemed. Your written step by step instructions worked better than anything. The pics helped with the placement of the exhaust gaskets/donuts. Thank you so much I could not have done it without your guidance. Thanks again have a great night. I have a few more projects I'll start new threads. Take care.
