Fitting a rear exhaust - any tips/things to watch out for?

Hi. I will (hopefully!) be fitting a new rear pipe/silencer box to an old Suzuki car very shortly. Never done one before so I thought it might be good challenge/experience. Also thought it would be good to ask anyone who has done one before (or indeed does it for a living) whether there are any important things to watch out for or tips/tricks to make life easier.

I gather the first problem may be siezed bolts in the joint between front pipe and rear. I should have new bolts/nuts and gasket so I'm prepared to have to cut/grind them off if necessary. I also understand that the rubber supports can be a bit stubborn too. Would a little squirt of 3 in 1 oil help ease them off/on again or would it deteriorate the rubber? Finally, would the joint (the twin-bolted bracket between front and rear pipe) require any kind of sealant or is the gasket all that is required?

Thanks in advance for any advice and best regards,

Phsy.

I find using an hacksaw on the u bolts is often easier than trying to undo the nuts, Plenty of wd40 on the joint, I like to prize the split joint open with a flat bladed object, Squirt abit of wd40 bang, twist and eventually it'll come off.

Use a bit of gun gum type stuff on the joint, New u bolt and new rubbers are a good idea, you could also dab a bit of washing up liquid on the joints that go into the rubbers.

Make sure the heat shield doesn't touch the exhaust as they tend to make noise with the vibrations, They're easy to catch and bend when working on exhaust.

Make sure you wear a cheap pair of goggles . Always loads of tiny bits of rust and crud to get into your eyes . WD40 best for easing rusted threads but you may need a nut splitter . might be an idea to replace the rubber hoops (supports ) then you can just chop the old ones off if they prove difficult to remove . If they come off ok and they're not split/perished they'll be fine .

Cheers for the replies guys. Yep, eye protection is deffo top of my checklist. I've lubed all the appropriate bolts today and will let it soak in for a day or two. Loved the washing-up liquid idea - however, all the rubbers are bolted on rather than just suspended from hangers! That'll prove fun getting all those off. Hehe. Typical. Oh well...
