MG MGF Technical - Rusty Exhaust

Dear All, i have a yr2000 w reg mgf an i have notice that the silencer (i think it is the silencer) is rusty. Is this a problem? will i need a new exhaust?

Cheers Andrea

What do you mean by 'silencer'?

Do you mean the tailpipe finishers, the connecting pipework or the silencer box itself?

Connecting pipework tends to go rusty, tailpipes should stay rust free, rear silencer box should also fair pretty well.

i presume the silencer box itself....at the seams either side it has gone very rusty.

Hmmm, not sure if it should do that. Corrosion on the pipework is fairly common, but the silencer box itself should be pretty good rust wise.

Out of warrantee? Might be a good idea to look into an aftermarket system, a fully stainless steel one that is guaranteed for life. Don't necessarily have to go for anything wild, MGOC Double S system is pretty quiet and unobtrusive, but is also well made and should stand the course of time.

Go for it

Loud pipes and no cat

Beautiful!

Chris and Andrea both need to know where and at how much cost we can get a full stainless steel exhaust fitted locally.
Thanks all ,

Providing you supply the exhaust...

Easy option: MG dealership can do it. This could be expensive though.

Next easiest option: Kwik Fit or similar. Should be less than your dealership, but probably not by very much.

If you know one, your local garage can do it - this is likely to be fairly cheap as the job itself is very easy, consisting of only 8 nuts (3 on the pipe connection flange, 2 on the support hook and 2+1 on the strap). However, the first three nuts tend to go very rusty after a year or so and generally are a right pain to remove.

It is for this reason that i do not recommend a DIY approach. It's not that the job is difficult (just nuts and bolts), it's because it can take a lot of time to remove these nuts and a garagr is better equipped to deal with them (nut splitters / oxy asceteline torch etc).

In addition to the exhaust you will need a new gasket (pennies). I would also recommend a set of Mike Satur's cat saver nuts - these replace the rusty nuts on the cat/exhaust and do not corrode like the standard fit ones.

Lastly, you should probably talk to your insurers too, some of them can be a bit picky regarding exhausts.

SF is absolutley right
I remember him wrestling with those same rusty and troublesome nuts under the back of his car in the Paddock at brooklands. Cool place to change your exhaust tho SF!

Ileft Cheeseman in Woking to deal with them when they put the cat pipe together, it may have been the first cat bypass pipe made for an F in Stainess! back in 96. It's nicely blued now though!

Get the MS cat saver nuts, or as I did in true Surrey Labs form. Go to your local motor factors and get some nuts of the correct dimension. The thread is quite large so as a result the nuts you will buy are pretty deep and beefy. They will do fine

For the MOT I can now put the Cat back in for its annual constitutional in under 10 mins and I dont even have to jack up the rear!
