I removed my header today to do some work in the transmission tunnel.. This is how a blingy SS header looks like under the exhaust wrap.
I have only used it for about 4 months during the summer and mostly trackdays except a trip to the Ring.
The exhaust wrap has effectively removed all signs of bling.  And never ever buy exhaust wrap from Biltema.  It's shite.  The little that was left of it pulverized in my hands.

Raceland mummy style.

 Closeup shows some oxidation I guess the chinese didn't use their finest metal when making these but this might be the same for any header:

When I put it back on I'll use another brand thats not made of tissue paper.
