That's not bad at all! I take it you had to send them in somewhere, or do any of the vendors provide that service?

Bringing this thread back from the dead.....
I recently purchased a set of headers (not coated) and was thinking about buying some wrap because according to RR-Racing's website, it says...
"RR-Racing recommends using 2" wide titanium DEI heat insulation with these headers. We also recommend wrapping the starter with heat insulation when the headers are installed."
However, I know this thread is old, but it appears that everyone is against wrapping the headers.
Has something changed over the past 4 years? Why is RR-Racing recommending to wrap the headers? They obviously know their stuff and have done plenty of testing....
Thanks!

PPE is also stainless, although, AFAIK, mild steel is a reduced price option> But, for me, I like the ceramic coating because it reduces the underwood temps, which can make those components around the headers last a bit longer. Remember the stock manifolds have a heat shield around them. Also, the black coating makes them more stealth.

A lot of misconceptions here. Wrap is only bad when moisture is involved as trapped moisture leads to oxidation and suface rust even on SS as not all SS inhibits rust.
For performance it is best to keep the heat inside the exhaust. Ceramics can drop header surface temps 2 - 300°F.
I would never wrap anything that is driven in the rain. That said humid areas can be just as bad. Coatings are best but shield or cover anything that needs additional protection. Reducing underhood temps saves, belts, hoses, batteries, sensors and our new friend plastic everything.
Keeping the heat in the exhaust is a good thing. Its how you do it that matters. Keeping in mind that many oem pipes are double wall partially for this reason.

Just got my PPE headrers from RR racing last week, and they really recommend wrapping them with 2" DEI Titanium wrap, anyone with PPE headers did it? I don't drive the car in the rain, or snow (Weekend Car).

DEI says you’ll get four to five years for the average person out of the titanium wrap. I’d say that’s enough to avoid wrapping unless you plan on removing your headers on a routine basis. That answers whether or not I’m going to be doing that.
Anyone want to buy some titanium wrap?

Do one or the other, never both. If you drive your car frequently you can eliminate the condensation issue (mine does 75 miles daily rain or shine). If you car frequently is parked I would have them coated and not worry about it.
