I used the DEI products on mine, including the paint. I used header wrap before on my racecar without the coating. The coating seals the wrap, extends the life, & IMO, just looks better. I'd recommend the paint if your going to wrap it up.

BTW, mine was rusty as......living on an island in the Gulf has it's downside.

I beleive somehwere i saw that addressed that it "could" possibly keep it from fading - I got the copper colored wrap and I guess i will coat it - said to wait until the wrap dried if using the water soak application method - I applied it yesterday - drove it long enough to get it good and hot - evap the moisture and rode it to work today - suppose I will get the spray and apply it tonight after the header cools off......just a few lite coats? anyone who has done it let me know.

did a little more digging - the material i used is the Titanium LR technology material - DEI says no HT coating needed.

yep i got 15' and it covered the header from the engine port to the union with the muffler. read somewhere that folks used 25' must have a healthy overlap - i tried to keep it at 1/4" overlap as recommended.
