Re: [DML] DMCH performance exhaust (and other stuff)



Hi Martin:

Long time no talk to.  Just for the discussion......

Yes, it is tiny RUST as pitting spots that is occurring on the header  
pipes which is localized close to the manifolds.....  YUPPO, that's  
what it is.

Personally, believe or not it or not, it doesn't both me for I do  
understand that is the nature and the characteristics of the actions  
that the material that will go through.

As far ANY product with "LIFETIME GUARANTEE???"   It is great to know  
as the "business policy" with the company.  I am across the pond and  
just to send it back is an extra job, as well in time and money.    
So, I did took that point into consideration. t is also one of the  
primary reason why I bought the UK system for I believe it to be the  
best that there is and that STILL hold true to till date.

As far 304 stainless goes, that grade will spot up if it is exposed  
to the elements.  I have had much experiences in the industry when I  
was manufacturing specific units for the aquatic trade.  This  
spotting effects has also occurred on my car when I drove it in the  
snow and I didn't clean it some two weeks later.  The spotting and  
the pitting was not deep, so out comes the Scotch Pad and the old  
elbow grease.... Now all is well.

For everyone's info, Rob at PJ Grady had a customer's car at his shop  
some years back the owner had a plastic cover on for a considerable  
of time.  During this period  of time, condensation had built up  
between the plastic cover and the car's stainless steel.   The  
results???  DEEP SPOTTING AND PITTING!!!  I was amazed to see the  
extensive damages that had occurred!  The car now has dark  
freckles..... Rob couldn't even salvage the surfaces of the car.   
So.......
