Tips for installing exhaust

I recently got the engine back in my 64 and am now in the process of re-installing the stock under chassis exhaust system. Car is on 4 jack stands, so about a couple feet off the floor. Based on your actual experience, what suggestions can you offer for someone doing this by himself ? I know a second set of hands would help but that is not an option for me. My problem thus far is getting the pipes connected where they go through the crossmember. Mufflers are on the pipes. System is not new but is not very old either.

Suggestions ?????????

Thanks in advance for your help.

Take note:

Make sure the two parts....will go together first...long pipe and part from exhaust manifold...you don't want to fight this working under the car...

Yep........................confirmed already Jack. When I hang the muffler and pipe at the rear mounting bracket, the front pipe won't go far enough into the pipe at the crossmember. I may have to take it to a muffler shop and have it swelled slightly.

Thanks,

I’ve installed welded muffler/tail pipes on my ’67 a couple of time by myself but I’ve had the luxury of having a hoist.

First, I hope you’ve removed or have the rear valence panel off – you’ll need the room if the mufflers are welded. Don’t attach the muffler to the rear mounting bracket - you'll start with the mufflers hanging down, then rotate them into position. Run the pipe through the frame and mate to the exhaust pipe. Move the tail pipe from side to side and up and down while pushing forward. The tail pipe should slide over the exhaust pipe. It can be a pain if the tail pipe has been compressed by previous clamping but it should go back together.

I have never needed to remove the rear valence. I put the rear pipe in there first the push it over the front pipe at the hanger.

If you're having a fitting issue going over the front pipe, rent or buy the tail pipe expander from your FLAPS and size it yourself. After the first sizing up, remove and rotate the expander tool to create a smoother opening.

If you ant a sealed pipe joint between the two pipes, use muffler cement just before the joining and then clamp together.

If you are building a new system and you want to butt weld it, I have found that when you align the part under the car, you can use 2" masking tape wrapped tightly around the weld area.

When you take it off for welding, cut out a small area and tack it, then do the other side. It keeps your alignment real nice.

If yoy are using a gas torch, you can weld right through the tape.

Problem solved.................................. .I installed one of my NOS N-11 off road systems. Had it on in 30 minutes. I guess there IS something to that GM sales pitch......................."Keep your GM car all GM".
