My 91 S4 has the black, dual pipe tips.

They're not too bad looking, but I'd like to take them off for repainting. It looks from PET as though they are a separate part - not shown on illustration 202-15 but there is a reference in part list to 'cover' 928 111 271 03

There are a couple of well heat encrusted 8mm bolt heads on the tips. I'm betting these would be easy to snap these so wanted to check how they are attached before attempting to remove - do they locate into holes on the pipes or just clamp onto them? Do the tips just pull off with the bolts undone? How simple is it to remove entire rear silencer is that is the way to go and paint the tips in situ off the car?

Thanks a lot!

When I repainted mine few years ago, I removed the entire silencer.

Not a big job at all.

- Lift the car;
- remove the two silencer clamp bolts, move the clamps out of the way (just slide them on the pipe);
- remove the nut and washer on the metal hooks and remove the bolts (2 if I remember well).

If I remember well that's about it.

Be careful, the silencer is quite heavy.

Thanks very much Bertrand - looks like a simple project. May I ask why you chose to take off silencer and not just the tips?

Actually, I don't remember Adrian!

Maybe I tried to remove the bolts and they didn't moved.

What I do remember though, is that I cleaned the silencer well while it was out!

I removed it a few time. To paint the tips, to put a RMB, put it back to stock for a little while, put the RMB back again...

Cleaning the silencer - what a good idea!

I'll consider that, but may put me on the slippery slope that ends up with mirrors to show off the underside!

Adrian,

Getting the thing off is easy - getting it back on if you are working from axle stands is a bit of a bear!

I was trying to fit my stock rear box last year just for a trial to see how it attenuated the rort of the RMB. That thing is dammed heavy- after losing about three knuckles work of skin I gave up and refitted the RMB- so easy. Whether you would have such issues no idea but just my experience.

The tips are held on by a set screw not sure what the remedy would be if the thing bust but doubtless it would be a solvable problem.

If you have not tried it and you can get away wth it, the RMB is a nice satisfying alternative but power wise it is arguably worthless- better to fit an x-pipe if you want a bit more power/torque. I have a Louie pipe, a custom mid section with a Bullet muffler and then the RMB- the sound is legendary in local Porsche circles! Even my wife picked it out down town one day some years ago- she heard a car roaring away- said to the girls "that sounds like your Dad's car" - it was and I was nearly half a mile away!

the tips are held on with a screw that goes through a nut plate thats welded to the tip cover.

trying to remove the screw will usually result in the screw shearing off ,
and then if it did turn,
you might be left with a rattling tip.

If you do feel the need to remove it I would suggest to use an induction heater on the bolt head.
when you get the bolt out ,
and it might have to be drilled,
the best way to secure the tips is with red silicone hi heat sealant smeared on the inside of the tip
