Hi Guys,

The rear section of my exhaust is badly damaged and needs replacing. I have the replacement section ready and I'm going to have a go at sorting it if/when there is a break in the weather. It's pretty low on my list of priorities but the noise from it gets on my nerves.

I've never done any work on exhausts before. I heard they are difficult to remove in sections. I've got the breaker bar on standby

The bolts on the section look ok though (not rusted). I'm planning on spraying them with penetrating oil before trying to remove them.

Is it worthwhile painting the section with fire paint before fitting to help preserve it? The rest of the exhaust is painted black - new section is bare metal.

I'll get some exhaust paste. Do I need anything else and has anyone got any tips for me?

Cheers.

The sections should be ok to seperate with sockets/spanners, depends how long they have been on for really and waht sorta work the landy goes through, if its really gunked up sometimes a cople of hits with the hammer to remove the surfact corrosion and then some wd40 should help, if its really bad then a cutter/grinder will help. But you shouldnt be that bad.. Cant give you any advice on the paint bud sorry,

As above...get the angle grinder on standby

No amount of paint will stop an exhaust from corroding as this happens from the inside outwards.

Good luck with the weather !!!

I'm in the same boat,and it must be done in the next week. I intend to cut the rear section just past the olive joint and attack those rusty bolts. I'm de-catting mine at then same time as the cat is leaking

As the guys above say - hammer at ready and start spraying penetrating fluid on the fixings now and repeat several times a day if you can

I was surprised how easily mine came apart 2 month's back

If it won't budge, apply heat and then hammer free - angle grinder is last resort and really shouldn't need

I had time to have a go at this yesterday and was stunned at how easily the centre section separated from the rear section. The amount of room that you have to maneuver under the vehicle is incredible and you really appreciate it when your doing a job like this.

The tailpipe had separated from the rear section completely so there was only one exhaust hanger holding up the entire rear section. I think I got around to this job in the nick of time before the whole lot came off.

I read that Loctite 5920 Premium Silicone Copper Gasket Maker works better than fire gum as it allows some movement so I used this at the joint. Seems perfect for now but it's early days!

Thanks for the advice guys, that's another job sorted.

If you're going to cut anything, cut the clamp bolts.

Then you'll find that the whole thing falls apart at the olive!

Nope, complete waste of time and paint cos they rot from the inside out.

Yes this is what I did. Then replaced with stainless bolts and nuts.
