Rear Silcencer To Middle Section Clamp

[WooDooUK 1]

Hi,

 

My current exhaust system is a Bosal patten system, but were the rear silencer meets the middle section is of a real odd design, it is like two trumpets with a two "u" shaped clamps going round it, (see diagram drawn with my awsome drawing skills )

 

However it seems completley usless and keeps coming loose, rattling and blowing realy badly, anyone have any suggestions on how to keep it all nice and tight? I tried gunking it all up with exhaust paste but it just delayed the same results.

there should be an olive between the two parts, fit this with a little gunk and it should be hunky dory

have you got a doughnut shaped ring in between the pipe ends?

Nope thatle be it then next question is would i be able to get one of these from Peugeot?

if you pop round to your local kwik fit/etc and ask nicely, they might let you have one for free (take the back box with you for size reference)

Errrm - what are you on about olives for???

 

The only place on a stock system there is an olive is between the down pipe and manifold! That is unless BOSAL decided to come up with their own unique way of clamping the parts to gether, but I doubt it.

 

Your dodgy drawing appears to be a badly drawn standard later design exhaust system, although I've never had a problem with these blowing. There should be one section fitting over another on a steep taper, not two flanges up against each other.

 

When I assemble them I just put a smear of Gun Gum on the two surfaces and clamp them up (remembering to keep the exhaust as straight as possible until clamped up). If the clamp gets loose then they blow like hell but also rattle as the clamp moves around so I'd expect you'd have noticed if this was the problem.

Phew, was panicking then wondering why mine doesn't have anything fitted inside the clamp.

 

As Rob says, the "Olive" is just the type of fitment, one pipe meets the other (rounded edges) and they are clamped together. Make sure all the surfaces are clean, get a good quality clamp and use some exhaust putty - always works fine for me.

I've got one of these on mine, its never not blown. But thats because mine is fairly low, and my local pub has Jordan sized speed bumps

 

But yeah, just wire brush, little bit of gum, and tighten the clamp up, just make sure the join is all square or else it won't sit well.

some systems (eg. Piper) have identical flared ends on both the intermediate pipe and the rear box (as appears to be shown by WooDooUK's drawing)

 

these flared ends obviously aren't going to match up to one another as the back box needs to be able to move in relation to the centre section to allow for correct fitment

 

you need one of these rings in between the pipes

assemble using copper grease

Id expect it to look more like this, but with the parts pulled together by the clamp, if the clamp isnt pulling it together try squashing the sides inwards with a hammer then refit it.

thats exactly what I meant by my post earlier,

 

modified this drawing to demonstrate too -

 

hope you dont mind me borrowing your pic ritchie

Excellent that clears things up nicley, Now off to learn how to draw
