Thank you,
should have them sections welded up to the bags on Sunday

**crumble** · 17-10-25, 06:22 PM

I will do a quality check over the weekend at some point.

**tom.marg** · 19-10-25, 06:02 PM

Finally a good day at the workshop.

I set about getting both pipes that link the centre section to the top of the air bags welded up. Then weld on the v band flanges.

The next point was to see if they still fit as there is a lot of joints and tight space.

They had moved a bit, I think it was on the V band at the join had a bend straight in to it rather than a bit of straight pipe, there for there was a slight bit of slack on the fit up, no Gap to fill on a join as such but thinking about might have moved in to the free space or slop on the flange.
They Still fit well enough so it was on to a quick mount set up. 2 Tabs on to the cross member and some small stainless mounts on to the exhaust, tack on remove exhaust again, weld cool and refit.

It can be quite time consuming!

next Is on to the fun bit. I thought that but was tough haha! The next bit has to come past down inbetween the tin work for the back of the boot and the air bag, avoiding the shock, then come along past the tank and in to the 1/4. Then finish at the bumper.

so great progress really, shall we say the bulk of it is done. Once the exhaust is all on I will remove the car from the ramp for johns new van to get in the air and have a full service and check over.

while he is doing that I?ll get on with some other bits on the floor, then back on the ramp to get the cross member back in and some heat shielding plan a fuel line route that looks as fun as the exhaust.

Nice work Tom, are you limited to the bends you can buy in stainless to get the right angles ? How about the turbo clamps rather than sleeved over is that more for maintenance work ?

**tom.marg** · 19-10-25, 07:00 PM

Thanks mate,
No you are not limited to bend angles usually, in this case I am using 316 stainless, 45/90 deg available. If using 304, you can get a wide variety of bends.

The 90s I am using can be cut down to a req degree no problem, I done this on the front sections.
the route taken here is not due to bend angle but more weve got one route through this gap.

Not sure what you mean ref the sleeve joins mate? Every join on this is a VBAND.

The normal slide on with a double slot as per most production stuff

Sent from my SM-A556B using NSRA mobile app

**tom.marg** · 19-10-25, 08:38 PM

Oh get ya! Yeah I don’t often do that method to be honest. I would like to but I would need a decent pipe expander for this 316, normal expanders don’t seem to touch the 304 either.
I like to use a nice clamp, it gets expensive but you get what you pay for.
I know a guy that always uses the slip connectors and has decent gear to make them with no big leaks ect some of them are proper poor.
I see a lot of after market exhausts fitted to production cars at work and they are often low grade stainless and poor fitment. Crazy what people pay for rubbish sometimes

**tom.marg** · 21-10-25, 08:49 PM

Tonights task was to remove the rear bumper and put proper sized bolts in the burner irons, check out some of the next route for the tail pipe sections and make some cuts ready for the next stage.

I removed the bumper and split the bumper irons, the ones fitted are possibly 50 merc with a 49 bumper or something like that one way round or another haha! We may make new bumper irons yet but for now just needed to remove one half of them to get out the way of the tail pipe section. It?s now secure enough to hold in place to work out where to dump the exhaust. 5/8 bolts holding the bumper irons on, these cars were built as tanks!

Next I made a cut of a 90 to make my ?turn downs? that are going to hide inside the curv of the bumper. In to the band saw x2 job done.

Next cut 2 500 mm straights and tacked the turn downs on to get a rough look of a ?run?

Tight 90 legs cut and then halved for a bit of a step curv that?s going to be needed.

Then cut down another tight 90 leg to then attatch to the v band that is now at the rear bag cross member and welded up.

**tom.marg** · 23-10-25, 07:48 PM

Another few hours last night getting some bits stuck together.
Down past the air bag, looks close, because it is. It will be protected. We also figured the exhaust heat would be cooler here than at the front of cars with headers near by ect!

**BadAC** · 24-10-25, 07:15 AM

Blimey, were you a snake charmer in a previous life. Ruddy good work.

**tom.marg** · 24-10-25, 04:07 PM

Haha! It does have some shape to it!

**mygasser** · 24-10-25, 05:11 PM

as it's up out of sight you could always put some header wrap round the section of exhaust near the air bag mate.

neil.

Yeah mate we probably will do, will get some good quality stuff and wrap it nice.
there’s some other sections that will need some heat Shields too.

**mygasser** · 24-10-25, 05:58 PM

by the plastic fuel tank?

**tom.marg** · 25-10-25, 06:40 PM

That area actually has quite a lot of room around it! No closer than production cars in fairness however it probably will get some saftey shielding once all this bit is sorted should be back in action tomorrow for some more work hopefully can get a good bit of progress ready for a shift around in the workshop

**mygasser** · 25-10-25, 08:59 PM

it was hard to see in the pics, i guess you could 'tiger seal' some of that foil type heat shield to the part of the tank closest to the exhaust?
neil.

**tom.marg** · 26-10-25, 06:10 PM

No mate that’s a bit of a bodge, if I make a shield I’ll have it bolting on so it’s proper job. The car is worth more than a bit of tiger seal lol.

Today was a great day at the workshop, other than it being cold, and I hate the cold!! Winter is clearly coming in fast I just had to crack on.

Carrying on with the exhaust system getting the driver side routed to the rear bumper and then the passenger side to follow a similar route but as always not quite the same!

The band saw was getting a work out and lots of tacking checking and welding Both sides are now to the bumper, they are pretty close to the same both sides but obviously being an old car that?s had metal work nothing is identical. We also need to get the bumper fitting bang on before the final trim of the tail pipe they might be perfect but we will see.

I am out of stainless flat so will order some more and make 2 rear mounts for that section.
Also not far off being out of gas.

In the week I hope to get the mounts made and then can just get a nice 3 inch bit of card board tube to check some prop clearances then it can come off the ramp and be parked for a short while.

not bad though, the car nearly has a fully working exhaust system, it?s been owned 15 years and we?re finally making some progress for them.

**crumble** · 26-10-25, 09:02 PM

Dude don't be cold. Their is a heater with about 100 gallons of red diesel.

**its still redoxide** · 26-10-25, 09:33 PM

Going through the same process with the exhaust on the pop project . I kinda enjoy the process and all the twists and turns , Not as many as youve taken care of here, but still a few to get things where I want them to be and a few additions just to add that visual to the system. Inspired by your fabrication.

Looking forward to your updates ..
