Magnex Exhaust

Post by elbon50 »

Have aquired a system made I think by Magnex themselves before takeover by Mongoose

A few issues have arisen on preparing to fit it

1. There is a bracket like this fastened to the back of the engine just forward of the driveshaft

Image

The foot of the bracket clamps to the stock frontpipe

Can't be used with my Magnex as the foot comes just where the flexy is located

Have removed it but not happy

2. The rubberised connector which supports the pipe is no longer available from Mr T & I need one :shock:

3. The rubberised silencer supports are no longer available under their original AW11 part numbers but Mr T has the same items under new part numbers (used on other models)

That's the first one of those I've seen that hasn't rusted through ! Don't worry about removing it - I've run 3 Mk1s, with Janspeed or Mongosse exhausts, all with this bracket removed without a problem :thumleft:

Thanks for that Martin :thumleft:

Will be OK so long as I can find a way of replacing the rubberised pipe support then

It does next to nothing, just leave it off, consider it weight saving, we know you like that. :D

The rubber itself doesn't look too bad - just clean it up ( and the bracket ) and stick it back in with RTV Silicone

Araldite is too rigid to bond to rubber. RTV should do the job though, just make sure the surfaces to be bonded are clean

There are two of these rubberised mountings, one at each end of the silencer

Image

The AW11 part numbers were 17430A and 17430S (although both seem exactly same to me)

The above numbers are superseded by 17508-16031 (evidently they're used on a newer Mr T model)

So no problem getting these at the mo (about £16 each :shock: )

I did away with this years ago and never had any issues without it. If anything it was limiting the exhaust movement and putting more stress on the manifold joint.

The short numbers you have quoted are not part numbers. They're just part description codes taken from the depiction diagrams.

A proper Toyota part number will generally be in the "12345-67890" format.

I agree but that does not alter the fact that those parts are only now available under superseded part numbers

The parts man at my local Mr T branch was able to confirm that from the description codes which I showed him
