Fitting Silencer

I was just wondering what the technique is for fitting a silencer. The problem would seem to be rather basic but results from the new box being slightly different from the original. My problem is how to hook on the hangers.. The original silencer had one of the hangers un-boltable so it was possible to slide in one side and then bolt of the second. The new stainless steel silencer has both hangers welded in place and I cannot see how it is possible to hook them in as there is not enough lateral movement available. The rubber mounts are hidden behind the heat shield which I assume is fitted first.
Any suggestions would be gratefully appreciated.

Here's how I did mine How to - Fitting a new exhaust.


But mine had a removable hanger too.


All I can think of is to release the 2 brackets that hold the rubbers in place, fit the rubbers to the hangers, put the exhaust in place and refasten the brackets to the car.

I saw your very comprehensive posting thanks. I thought about removing one of the rubber mounts but the trouble with that is that they are under the heat shield which has to be fitted before the silencer I guess.

Same as mine issue.
The rubber I've got are really near end of life, but to change them, I have to remove the shield, lump of rusty metal (that were nuts?) .... 5 hours job.

the exhaust mount rubbers fatigue with age,, the mounting points need one particular consideration above all aesthetics. That is - that the flexible is true, without kinks or s bend misalignment.

To achieve that may mean modification or adaption of the " new" verses the " old" and yes its a long process.. there is no easy one stop,end all solution. it requires on to fit the exhaust based solely on ones own experience, and observation of reaction to change,, it really is its own thing... not one anyone can can say.. " do this" because there is no " do this" just pointer replies.
and getting the exhaust outlet pipes true in the flexible joint and true in the bumper is not something anyone can tell you how.. not me... at least...
its yours.. fix it.. if you cant pay someone to fix it for you.. its your choice.

This seems more a dialogue for someone that is embarking on the trip of his life, rather than something more mundane...

I have tried dry fitting the silencer without the heat shield and by removing the rubber mounts. This made it very clear that it would be impossible to fit without doing this as the hangers protrude through so far. Hopefully the pictures show what I am saying. This begs a couple of questions. Has anyone managed to fit a heat shield after fitting the silencer and how essential is the heat shield.

I had to open the bends in the hanger to get mine to poke out in the right place. Not to hard

Have you asked the supplier or manufacturer for some guidance?

Long shot maybe, but you would like to think that someone has thought about this, not just blindly started selling a silencer that nobody can fit with a heat shield...

I would have thought so Ian. I wrote to the supplier who said that he had not had any complaints before. I actually didn't complain just asked for advice. All the other examples I have seen had removable hangers on one side like the original. I was just hoping that I was missing something obvious but I am not sure what that could be!

I've a powerflow stainless system on one of my Tf's, welded on hooked either side and seriously rusted bolts making it impossible to remove the hangers. ended up sliding one side hook into place on a hanger then used a very large bar to bend/force the final hook whilst using a large screwdriver to prise into place. I then bent hook back to shape. I will add, the prising didn't do the heat shield any good but the exhaust hasn't needing moving since so all is well

Can't you reach the bolts under the heat shield with a ring spanner or cut out a small section of the shield?

Modifying the heat shield is the next thing to try!

I was fortunate having fitted new mounting blocks and a new heat shield a few months ago. Apart from having to reshape the hangers to get them to fit at all I removed a mounting block using an open ended spanner, refitting was a pain but managed it without damaging the shield. Have recently used the oxy torch to adjust the hangers again so the tailpipes were level

ok... forget about the old heat shield fixing points... they will have rusted and seized screws that will round and break off when one tries to free them.

get some new penny washers and new screws.. of your choice..

break away the heat shield around the rusty seized fixings.. free it and take it off.. you can use exhaust paste and thick aluminium foil, or plumbers heat mesh pads ( from B and Q http://www.diy.com/departments/bq-so.../161521_BQ.prd ) _ which will stick to it.. to repair the heat shield where its damaged, and reinforce those holes and patches with heat mesh, as you need to... the whole repaired heat shield can be sprayed in silver exhaust paint..

when you have freed off the exhaust mounts and done repairs.. replacements etc.. you can put the whole lot back together..

using the new penny washers and screws you have bought.. and drill in new pilot holes, close to the old fixing points or where you want to.


?

i told you in my first post .. you have to be inventive.

not least.. you could make a new heat shield from scratch using Mocol heat shield cloth and Zircotec from example http://www.demon-tweeks.co.uk/motors...ing-protection

Been there done that too many times. Again today too!

For the amateur DIYer with limited resources, working under a car such as when fitting an exhaust etc is one of the least attractive and tiresome jobs.

Did just that today on my MG ZT-T 1.8t with the MG6 engine I fitted. I now have a near silent ZT-T. Previously sounded like a BTCC at full bore!...

My Exhausting Thread here

Before removing those heat shield bolts, I gave them a good soaking with Penetrating Fluid. After a five minute soak, I was relieved that they all came undone without breakages.

Penny washers ... Same problem so been there done that today too. :~


Apparently ... in a parallel universe MGJohn drives .........A.......

Arrrrrggghhhhh......... ......

Thanks everyone for all of the replies. I managed to fit the silencer by modifying the heat shield so that the rubber mounts were visible with the heat shield in place.

To those with answers that related to stuck fixings that was never my problem as all came out relatively easily.

Changing the stainless silencer was part of cleaning up the underside and now with a cleaned up hammerited subframe the underside looks the business. Shame no on one will see underneath:-) Hopefully now with the car now residing in dry old Spain, I won't be doing that job again.

I have to say that these days I am finding it hard just to do the job in hand and get sidetracked cleaning everything up before they go back. Goodness knows how long it will take me to something serious if or rather when it occurs.

Next job is to prepare the car for the equivalent of the Spanish MOT prior to importing it and putting Spanish plates on it.

PS Not sure why photo transferred upside down!
