Exhaust Broken

Hi,

1985 Mk1 Cab 1.6L GL

I am wondering if anuone can point me in the right direction with finding a replacement back box/rear silencer.

Mine decided to completely detach itself from the backbox and so now sounds like a monster truck…

I have looked breifly myself, but seem to be many variations.



TIA

plenty on ebay, you decide, performance/steel/stainless, diy or exhaust centre

Thanks, just wanting to replace the rear section.

Just seems to be multiple versions for different years etc. So wondered if anyone knew of anything exact so the mounts were in the correct position.

The engine code and the last the last 8 digits of the VIN would help to narrow down the correct VW part number

I do believe that you will need to replace the Piping between the resonator, and the rear silencer.  

This is why I hate Exhaust work, and leave it to my trusty mom&pop shop.  

If you do decide to go the whole route, then may I suggest that instead of using the old fashioned silencer clamps (We call then muffler clamps over here.).
That tend to Crush Pipes and distort them making them a PITA to remove or re-use piping with out a Pipe expander to straighten out the kinks.  

OLD style


NEWER style



Use SS band clamps as they come in different sizes and can be bought to reduce diameters as well.



They clamp circumference of the pipe with no distortion
and the pipes can't wiggle loose or leak when the pipes are cut square and butt up to each other.

Thanks a lot for the detailed response! I will certainly take that into account.

Is the reason in having to replace the pipe work between the resonator and back box due to not being able to buy a replacement where the pipework is welded/attached to the back box and the first connection is before the resonator as it is now/originally?

If the replacement silencer has the feed in port that is sufficiently long enough to be attached then no but your pipe looks to be a little brittle (weak) and maybe not last long.  Just my observation.

EW Engine Code.

FK019892

Not sure if that helps.

For your engine code and VIN, the parts diagrams suggest 155253609B was the original part number, with long-life alternatives 155253609C or 155253609P. A quick online search of availability using these exact part numbers doesn't look that promising

Thanks a lot for looking at that, those numbers look to be exactly what I need.

As you say though, impossible to find anywhere that has one.
