Got Exhaust Wrap?
Yo guys, my girl just got me a downpipe as an early Christmas gift. It's a slightly used Godspeed and I got it locally for $180.
Now I need to wrap it, so if any of you guys got any extra pieces laying around or some up for sale at a decent price that would be stellar!
Thanks

You can buy "Black Shadows"..........I don't have that much cash. I was hoping some of you guys had decent strips left over that I could prolly piece together....ghetto style!

I got some wrap from this site - seems to be very decently priced. For my Bosal DP, 1x50 roll was just enough, with maybe an extra 20 inches of leftovers. They also have the protective spray for around $7 a can. :banana:

For those that order heat wrap tape, the narrower tape allows you to conform better to more tightly curved tubing such as headers, while the wider tape allows faster coverage for things like downpipes and mid-pipes. Someone sells high-temp adhesive tape to hold non-adhesive heat wrap in place but you can also use stainless worm-gear clamps around tubing in most cases.
Those Eastwood prices are pretty good. :thumbs-up:

Heat wrap
There are pro's and con's to Heat Wrap.
Pro: Once the heat wrap is installed. You could place your hand on the part that is heat wrapped while the engine is running. It's that effective in shielding heat from the source. It will definately lower underhood temps.
Con: With an unwrapped pipe, the heat on the metal can be dissapated. With the wrapped pipe, the heat has no where to go and starts to cook the metal that is wrapped. This might not be a problem with a high grade stainless steel, but if you are wrapping cast iron or mild steel, it will do some damage to the metal and the metal will start to break apart.
I wrapped my (mild steel) downpipe on my Grand National and it cooked the crap out of it, cracking it in multiple places in the wrapped areas.
I decided not to go with it on my Stainless DP on my WRX.
The uppipe would be a good pipe to do since you want as much heat kept before the turbo.

"Nixwrx" have you noticed a decrease in power after the car has been running a while? I would think that some sort of shielding would be necessary since even the stock DP is shielded.
Anyone else not using exhaust wrap on there DP's?

The factory shielding on the DP helps with the underhood temps but does nothing for HP.
I've also never heard of any claims of HP with wrapping exhaust. IMHO, Wrapping does almost nothing if you have a cold air intake and a sealed hood scoop to your intercooler.

I have the Bosal, and have NOT wrapped it for the reasons that nixwrx listed. If anything, I would ceramic (HPC, Jet Hot, etc) coat it. Gives the benefits of wrap WITHOUT the downsides.
And if you have any fluid leaks (i.e. oil or tranny fluid), header wrap is an underhood fire waiting to happen. Guy I know in Houston lost his Syclone to it : wrapped downpipe.....tranny fluid leaked into it and instead of harmlessly burning off slowly it gathered in the wrap and then caught fire all at once. Truck was toast before they could get an extinguisher under there
