I was thinking of having the sectional exhaust fitted first by a garage, then it will allow you to remove sections as required to do the other stuff. A newly fitted sectional system should dismount very easily, especially if the garage knows your intentions.

I've done a few exhaust changes using ramps at the back and axle stands at the front. Bit cosy underneath but do-able.

Forget the old adage about measuring twice and cutting once - I measured three or four times just to be on the safe side.

Have a look at my suspension topic.
Listen to this guy.

The exhaust does NOT have to come off to do the jobs you have mentioned in the OP. I should know, I've just done all of them and more, and the exhaust is still untouched and original.

Thanks Jim.

Yes I read your suspension overhaul thread earlier and it's packed with really useful info.

I'm not sure how low I can drop the exhaust without bending/breaking the cat. Which part of the system was able to bend enough on yours?

Btw, while you're there - do you know what the part numbered 3 here is called? (I borrowed your pic). Also, what green and black paint did you use on those refurbed parts?

As Jim has mentioned, removal of the tunnel braces will allow the exhaust to drop to the ground, but as mentioned also previously, support around the flexi.

As I was doing mine in the street over a 5 day period, I also supported it on its length using bungee cords.

Once lowered, you can move the pipe around a fair bit to allow easier removal of the subframe.

Be careful when lowering it though, it is heavier than it appears, but is quite obvious once underneath.

Whilst you are under preparing for the task, spray all nuts and bolts with some proper penetrating fluid and go over them with a wire brush too. It all should be pretty obvious once under and looking at the components.

Where is the flexi-pipe Alan? I can't see it without crawling underneath (which I can't do until the support sleepers arrive).

Is there a penetrating fluid you'd recommend? I've only got WD40 at the moment.

Also, since that new Bosal was just installed, it should be simple and easy to take that off before you lower the rest of the exhaust. That will take a lot of weight strain off the flex pipe and you.

I make my own penetrating fluid - 50/50 mix of ATF and acetone in a squirt bottle. It's better than anything you can buy.

Cheers,
Glenn

Flexi is at the bottom/back of engine. Once the tunnel braces are off, and you drop the exhaust it will flex down from there.

The Bosal/Klarius parts aren't on the car yet - I won't install them until the subframe has been swapped over.

ATF + acetone sound interesting. I used to use PlusGas but it's getting mixed reviews these days.

Interesting comparison here - https://www.youtube.com/watch?v=xUEob2oAKVs&vl=en. Acteone/ATF comes second behind Liquid Wrench (link). PlusGas wasn't in the test. Results are at 8m approx. if you don't want to watch the whole thing.

Ah, that explains why I can't see it.
