Well I've put 2 metres right around the perferated tube which is just of 5 times round but I've kept it as lose as I can mainly so it can expand and knot together Luckily the 2ubular perferated tube is right in the middle ( square ) I had a nightmare with the Tullet to because of the way it's offset I've took all the wire wool out Which has made the back box very light compared with before Let's hope it holds in for the year Can you explain the grease around perferated tube sizeten as I don't quite understand the advantage of it ?

Just needs a new kid on it now



The steel wool took some getting out

Is there and mileage in adding a tip like the Tullet on my system with the perferated internal ? As mine currently is just cut of bit of 3" pipe

I've read that resonated tips can help a little bit but am not sure I believe it in the real world.

Im going to extend my tip anyway as the exit is very close to the clam ( flame damage )

So may aswell put a resonated tip in
To see if they work

I'm also going to put a false tip above to make mine look a bit better
I'm also going to put a DB reducer in the false tip



So it can be moved down stairs if it's needed

The top will also be slightly set back from bottom one
So if the static tester pics up top one there will be a lesser reading 😜

grease inside the exhaust is common practical joke that garage mechanics often do each other. smokes like crazy.

Those dB killers do work, I made one for Nipper and it dropped the noise by nearly 3 dB. However, you need to be aware that they create a good deal more back pressure, so your fuelling may be affected (though your ECUs will modify the fuelling tables appropriately over time presumably). Also your cylinder head temps may rise a bit.

I will have a seperate map for it nev which I can call up on

[siztenboots]

if you know the rpm range of the static test , then you can map that area for less noise , it would not impact wide open throttle performance, just low load.

I'm sure someone at VW could help out here

Great idea

This came today



And knocked this up

Could you show a few pics of how the exhaust box and the plate over it is attached and lined so that the gases dont escape please?

[CHILL Gone DUTCH]

I've just made the plate ATM nev I've been work to today It will over lap and have many riv nuts around it To clamp it down If it leaks which is unlikely until the wadding falls out 😜 I will put exhaust paste around it

I was going to cut it out of the wife's stainless steel dust bin But decided against it 🐔

just use pop rivets + paste (or silicone stuff, as that can have some heat). Drill-out/replace when repack is due.

Checked my spark plugs after around the 300 mile mark and 1 track day



There is little browning around the insulator so may still be a little hot running but will leave them for now and check again after croft on the 13th so may go up to 9s

well margo is back together 

 

exhaust was a bit of a PITA but got there eventually 

 

at bedford the static test was 99 Db today a unconfirmed reading of 92Db was recorded at static 

 

the car is significantly quiter especially when cruising around

 

the car was not as quick as it normally is though ??
