Title: Exhaust fitting advice
Post by: SMD on 29 May 2012, 12:42:31
Want to fit my exhaust this weekend and due to the size and weight of it and not having done it before, I thought I'd ask here for tips.

I'm aware that the hardest part is probably drilling out the bolts if they snap, I'm kind of prepared for that, will try to source pluggas and got a blowtorch and drill bits ready.

Fitting the exhaust, is it better to fit the centre sections first and then fit the rearbox or vice versa? I can't imagine making the whole thing up out of position and then fitting would be a good idea.

Cheers

Fairly straight forward to fit. You have already mentioned the problem and as long as you have a decent drill and bits you should be ok.

That's how I did it  :y. I completely soaked the bolts in Plusgas a few days before. I fitted the centre sections on the hangers first, loosely fitted the cat bolts and then wiggled the rear box on. The rear box is the only awkward bit. Assuming it's a V6, you have to wiggle the two pipes on equally and then lift up on to the rear hanger. Check that the pipes are level in the bumper cut-out and tighten all clamps and bolts.
I did mine with just the rear wheels on ramps because thankfully my bolts never sheared so I didn't need to get under the car with a drill.

Regards
Alan

I loosely built my V6 exhaust up on the ground & lifted it up as a complete assembly.  ;) Infact I made my Senator's stainless system up as a single exhaust & lifted that up as complete assembly too.   ;) ;)

I fitted the lot as one last weekend, it was a little unwieldy but I popped a trolley jack under the backbox to aid getting it up high enough.

Andy, omigo,

Was it fiddly getting the hangers into the rubbers mounts when as one unit? The hangers are on different directions, unless you can slide them on.

If you take one rubber hanger off, you can hang it from one rubber hanger and then slide the second rubber hanger on afterwards.  :y

That's what I hoped. Thanks for confirming

I'm glad YZ250 knew  :), it was years ago when I fitted my (stainless) exhaust & I'd forgotten  ::)

Last time I did mine...

Assemble loosely but so it doesn't fall to bits when man handling first. Make sure you have all the right bits and that they do all actually fit together.

Slide the whole lot under the car, once the old ones off. Lift the silencer end onto the appropriate hangers. Then lift the cat end into position and fit the bolts loosely. Fit the rest of the rubber hangers.

If at all looks ok and fits correctly, do it all up and fit the clips that stop the rubber hangers sliding off. Not forgetting sealing paste on the joins.

Re, exhaust paste. Should I make it up, trial fit it, if ok remove and paste joints or shall I skip trial fit stage and just paste it up? How long does it roughly take to harden?

You'll be able to fit your exhaust before it hardens, it goes off when heated ie when in use.  :y :y :y

Wipe the joints before you fit it.  :y

I appreciate everyone has a method that will work for them, but I do mid sections first and then offer up backbox.

My biggest tip:

Night before you start: lots of plusgas on cat bolts.

5 mins before you start: same

Directly before you start: Same

Or just chuck it all in the car for 9th June and I'll fit it for you / with you :y

James, I wont say no to that!  ;D  Cheers buddy, although I think it will take more that 1hr 15mins this time because dont forget the waterpump needs changing too and that would take, I dunno 5 mins  ;D

I loosely join the bits, then hand the centre boxes on hangers, then hang rear box on hangers, then do up stuff.
