Sidepipe slip

[Stu J]

During the past few miles I have noticed that the actual sidepipe is just slipping away from the header by 3 or 4mm, I am sure that several miles down the road it could possibly get worse.
I don't really want to pack the header with paste in order to glue it, has anyone ever had this problem? how did you get round it?

Which joint is slipping? If is the one where the elbow connects to the actual side pipe then it must be the brackets that hold the pipe to the chassis that are allowing the pipe to move backwards. If you have just used a strip of steel bar with one bolt into the chassis you could drill a second hole and stick another bolt in. Personally I do not think that strips of steel are good enough and that they will crack across one of the holes at some point in time! (but I'm a fussy bugger!)

If it's the joint where the header connects to the elbow you could try two "U" bolts instead of one!

Edit... just read you post again, I'm surprised the the head/elbow joint is slipping, they are normally a right git to get undone! Make sure that at least one "U" bolt is over the slots in the elbow so that it can force the elbow to clamp down on the header.

Hi Stu

I got round this problem by drilling two holes through the sidepipes and the headers then keeping it all in place with a couple of self tappers

Thanks for your replies, Pete your first paragraph is correct so I may try the 2nd bolt idea, however would the self tappers lead to an exhaust leak Warren and work themselves loose after a while? I presumed you drilled underneath so the screws could not be seen too.

Hi Stu,

I certainly don't want to start an argument but IMVHO self tappers are just a bit too far on the bodgy side of things!

You really need to knock up a good set of brackets and only use the rear mount. In my experiance if you use the front mount the exhausts end up acting as a engine anti rock device, they don't last long doing this job! (The bolt that Pilgrim tack weld on to the bottom of the exhaust snaps off)

You can then weld the bolt back on and weld all the way round the head of the bolt. The result is that a lump the size of a 50 pence piece then snaps off the exhaust!

Below are some mounts that I knocked up, they might be considered a bit OTT but they do allow the front of the exhaust to move up and down and won't snap!

I know that people have got away with just using strips of steel, like a said AJMHO!

The exhausts are 4" custom chrome, and the brackets are similar to what you made but not as grand plus there is only 1 bobbin on each bracket.
I shall make up some new brackets with 2 bobbins and put 2 holes into the chassis as a "lock", I also think it is agood idea just having 1 bracket either side giving flexibility too.

I did not want to start drilling the pipes because in a way I agree with your view but it was a idea, cheers Warren.

Good one!

I'm sure that your new brackets will sort it out. The two bobbins stop the pipe flopping about but still allow it to move up and down very easily at the front. The square plate goes inside the chassis to spread the load.

Good luck,

Pete
