That pesky Exhaust Rattle Again!!

[Len]

See i'm convinced its some ancillary metal piece.

Yea i have been thinking of putting in a new SS system. Just wanted to sort this out first!

Here's another thought - if you buy a SS system does it come with a new CAT or do you use your existing one?

I think you either get a 2 piece kit, i.e. mid and back pipe, with joins after the cat, or if you do get a 3 piece kit then i would imagine you would not get a new cat, as this would probably double the price of the system.

Hope this helps

Yea thats what i was thinking. Coz a SS sytem is 250-300 quid and a CAT is nearly that on its own.

But then Mild Steel and Stainless dont mix! On their own they start a chemical reaction and corrode. In an exposed wet/salty area under a car it must be accelerated. Hmmmm have to do some investigation.

[mrwotto]

well the cat fits inbetween the front pipe and the mid pipe, so everything should be ok!

As the cat is not made from metal!  Or at least i think not

The outer casing is! The ceramics and other stuff is inside.

i think most are "cat back".. thats what i meant

Right just been to mates garage, put it on a ramp straight away!
I sat in the car to set the revs to where it sounds, 2250rpm and two of em go underneath with large implements! Touching, banging. levering etc.
Outcome is its the from pipe/downpipe!

Now this is what was said:-
Its a pig of a job, prone to snap and then its a manifold off job, so best leave alone til it starts blowing.

Now i know this guy and when u hear pig of a job ya know it means he dont wanna do it!
So i live with it for now!

Only one solution I have come to terms with...
Leant to love your rattle:)

My Mk3 8v ADY sounds like the valves are about to fly through the bonnet at 2800RPM. It's the heatshield just behind/below the manifold in my case. The VW garage (unnamed so as not to incriminate) recommended a whole new exhaust system...!! (phuq that!)

So I'm climbing in tomorrow and apply some gentle pressure with a 16lb lump hammer...... again.....
