Exhaust knocking on rear beam.

[Chris-White]

Also, there is nothing worse than laying on your back in the cold and pissing rain trying to sort your exhaust out, especially if it is someone else's fault that it isn't right in the first place

I had good times doing that.

seriously satisfying throwing your ratchet spanner with accompanining 13mm socket out from under the car and off down the road whilst shouting ''f**k it i'll take it to kwik fit tommorow''.

I had a similar problem with a secondhand scorpion exhaust.  If you are still struggling take it to a custom exhaust builder like a Powerflow agent.   10 minutes and a fiver later it was sorted... but only by them heating up the pipe which runs over the beam and reshaping it.  The original exhaust fitter was a bit 'chicken' and just fannied around with brackets and clamps.

My Milltek came this morning, I will let you know how the fitting goes

I've solved the old exhaust knocking on rear beam problem by doing the following:

Slacken the join between the back box and the centre box just in front of the rear beam.
Gently tap the rear box so that the joint slides apart about 5mm then retighten the clamp.
This should raise the front of the back box ever-so-slightly and was enough in the case of my exhaust to cease that pesky banging!!!

Another adjustment I've had to make is to slacken the joint just in front of the middle box and give the whole rear section a twist to raise the back box up. You then however run the risk of the rear section banging on the rear valance/bumper etc.

Using these adjustments you should definately be able to get sufficient clearance and given that the pipe has only just been fitted everything should come undone nicely.

Let me know how you get on mate.
Definately needs adjusting, will suggest said tweeking to them when i take it in next week.
Was also thinking of taking it over to awesome for them to do, anybody got any views on that?
Cheers for the replys everyone, will let you all know how it goes!

Yes i supplied all new rubbers but have since seen poly ones available. Are they any better do you think?

Great advice, i will be suggesting all this next week at the garage, thanks

well after about 3 hours lying on the floor trying to fit that beast it went on without too many problems. Just very fiddly when youve only got the car up on axle stands. I had to modify the two hooks on the backbox as they were much further apart than the old one i had on, so i bent them closer together to make the rubbers nice and tight.

No knocking on anything yet, although fitting the centre section to the downpipe didnt go too well as it seems to be blowing a little from there
