Jet-Hot coated PPE downpipes heat test.

[Zpak]

And the verdict is... Touchable at full operating temp. 245° was the highest temp I could find. While obviously too hot to handle or keep your hand on I was comfortable feeling all around the pipe without fear of burns.

I really wish I would have done the same test with the factory pipes but, just couldn’t wait.

So if for no other reason, at least now my PTU fluid isn’t being cooked by the exhaust.

Cool ! Literally. Ha !

Catted or open Dp?

 

[Zpak]

Catted, bolted to stock cat back.

I have touched the factory pipes with no coating. I can vouch that they will burn you and you won't touch them a second time.

Cool to see....and touch apparently

That's damn impressive considering most Cats run in the 500-1200 deg F range. Lets just say you've got my interest! Off to their web page I go. Ball park price on what you had done?

 

[Zpak]

Sure is. Like I said, I wish I would have gotten the temp readings with the stock setup. Even someone with wrap would be interesting to see what there’s is.

It was $440 for the catted PPE downpipes. Test pipes would probably be cheeper. It’s all about surface coverage.

where do you buy the PPe down pipes from ? and do they offer the coating service ?

You can go directly to/through PPE themselves to order the DP's.

They DO NOT perform the coating.

However, PPE will coordinate with JET-HOT and drop ship them to JET-HOT in order to have the coating applied.

Once JH is done, they then will ship the completed product to you.

thank you so looking at about $1,500 for coated down pipes ????

Yep. I feel a bit bad but I actually ordered mine from Vivid Racing due to the fact that the pipes were almost $200 cheeper than directly from PPE. Though, I was in contact with PPE during the build. Once completed they were shipped to Jet-Hot for the coating. The whole process took just over two months from the time I placed the order for the pipes till I received them looking all pretty.

From my understanding over the years, Jet-hot coatings only add a layer for the heat to push through. But, eventually, they will see the same radiating heat as uncoated metals. Apparently Jet-hot uses shiny coatings for their "lab tests" which reflects the IR light that the lens is trying to measure. So the lower heat reading is inaccurate. I would stick to heat wrapping if you want to contain the heat and reduce radiation.

I’m not doubting you on the accuracy of my harbor freight IR thermometer. However, my hands touching the pipe and cat while running at operating temp told me all I needed to know. To be honest, I thought the temp readings seemed high in relation to how they felt. Blasting through gears I’m sure would change that, but I know it’s still far better than nothing.

Will it last forever, who knows? Only time will tell. But, if they don’t they will be re coating them for free as they are guaranteed for life.

Lastly, my car sees snow, rain, salt, and all other forms of muck the winter roads have to throw at it. Wrap isn’t an option for me.

I would be curious to see the temperature variation after say an hour of driving or several wot pulls.

What type of heat wrapping do you recommend?
I'll be doing the down pipes this spring.
Thank you

DEI Titanium wrap has been my go-to. If you have never wrapped exhaust before, you want to wet the wrap (keep it in a bucket of water as you wrap). This keeps the fibers under control. You will want to wear gloves, it's itchy like fiberglass. Also start wrapping from the furthest point away from the engine going towards the engine. This makes the overlapping edges face the rear of the car. Pull the wrap tight each wrap and overlap half of the last loop. lastly, DEI also makes a silicone spray to help seal up and protect the wrap. The only part of the spray that sucks is you need to cook the wrap onto the pipe first then spray it. So you'd have to wrap it, install the pipe, bring the engine up to temp, cook-off all the water, then uninstall and spray the silicone on.

Thank you. Wow, nothing worthwhile is easy.
