post edited. can see now?
Yup, can see now. In PC. Tks!
However, still not show on my iPhone.
Feel rust due2 corrosion by by-products of combustion eg acids.
Probable causes :
1. Poorer quality by vendor who supplied the one used in yr car;
2. Type of fuel used...any additives added?
3. Is yr catalytic converter still part of yr exhaust sys?
4. A lot of short runs...
and mayb some other reasons?
Here is my ride's exhaust tip @12 mths...to compare...

Added on March 18, 2012, 5:18 pmps. I read a suggestion in Safer Motoring mag (in my ole VW 1300 beetle days...) to spray new engine oil into exhaust mufflers/silencers & tailpipes to extend their lifespan...

Mayb I shld start now...? B4 any rust takes hold?
Most probably too late now...internal rusting cld hv started!
