Hey everyone,

You haven't seen me around these parts yet, but my name is Lukas and I'm the Buyer for Massdrop's new automotive community. Massdrop is a community of 1.5M people who discuss, vote for, and buy the best enthusiast products in groups.

We recently ran a very successful group buy in the C7 sub-forum for the Z06 rear quarter panel vents and had 45 people join in. Here's a link to that thread.

I've been working closely with DEI the past few weeks to work up a deal for you guys. We're very close to having a group buy for their Titanium Exhaust Wrap locked down, but I wanted to do an interest check to see how many of you guys would be interested in something like this.

Just reply to the thread below and I'll add your name to the interested list! I will personally message everyone who says they are interested if and when the group buy goes live.

Bought 2 50' rolls 3 weeks ago. Great stuff.

Does it create rust and rotting?

Ive always heard to never wrap exhaust if you want it to last. So Im curious too.

You can prep a header to help it last. Biggest help is with underhood heat.

Why else would an EXHAUST wrap exist? They serve their purpose to keep engine bay temps down. For us supercharger guys whose intake usually sits above the headers it is greatly worth it.

blackozvet

it depends on what you use it on, stainless, chrome plated and coated steel is ok,
mild steel will rust with wrap on, this pic is after wrap was on for a short period of time,



but sometimes its a necessary evil, I have wrap on the 4 right hand side pipes as they go past the starter motor and the wiring looms, If I have to cut the pipes and fix them down the track so be it.

My current exhaust is wrapped by the previous owner. Ive never used the stuff before as I always heard it will rust out the exhaust which is why I was curious.

If it cuts under hood temps and is proven to not rot coated headers I may be interested.

Will the vendor please clear this up.

years ago I wrapped a set of coated hooker headers for a street car which saw drag and auto-x use, it was a double edge sword. for the positive, the wrap greatly reduced under hood temperatures. I even dropped a bolt on the headers while it was running and just reached down and picked it up without burning my fingers. negative, it retained so much heat in the header that the structure of the metal was compromised: it got brittle. I also didn't start the wrap for 6 inches from the header flange, that is where most of the heat is that would deteriate the header. when I pulled the headers, they were nasty/rusty looking from getting wet then extreme heat.

Hey everyone,

Thanks for the informative and civil discussion about the wrap's effects on the pipes.

Blackozvet and Sleazy Rider, were you guys using the old style wrap or the newer titanium (lava rock) stuff? I'm going to ask DEI if the titanium wrap is any different with respect to corrosion. I have a feeling that the material of the pipes has a much larger impact though.

I ask in the other thread he sent me here. Looks like we will have to wait till next week.

blackozvet

I have used the common style wrap, Ive used it on karts, motorbikes, and cars, and yes the type of header material does make a difference. Stainless seems to be the most resilient to being wrapped.

A mate of mine has the titanium wrap on his coated headers on his Dodge racecar engine and has had no issues with it after 2 seasons.
Im pretty sure he used the spray sealer on it.

Sleazy Rider

I was using the old style wrap. back then all the write-ups were saying not to wrap all the way to the header flange because of all the heat retention in the first few inches of the tube caused cracks in the metal if using mild steel headers. stainless steel headers resisted heat fractures better.

Hey guys,

A couple of you had questions about the wrap, I reached out to DEI and these were the answers I got.

1. How does water affect the wrap and pipes?

2. What type of under-hood temperature reductions should users expect with the wrap?

3. How do the fiberglass and titanium wraps compare in terms of absorbency?

They also said that stainless steel or coated headers will of course be more resistant to any corrosion or rust than mild steel or uncoated pipes.

Hope this helps.
