Exhaust / header wrap, good or bad Options

[Joe Ricard]

So while I was laying there under my car (I just do that) while swapping out the transaxle I noticed something.
I looked down the SSI pipes and saw nice clean (like perfect burning plug color) from the exhaust port all the way to the line where the heat shroud stops. After that the pipe is black or very dark brownish black out to the flange.

So would wrapping the rest of the pipe in header wrap maintain the heat and extend the better burn all the way through the pipe? Also will wrap the Bursch collector pipes.

Bottom line will it make more power!

Be very careful with heat wrap on a car that leaks any oil.

I have a wrx and frequent the wrx boards and one of the things we do is swap out up and down pipes on the turbo.

One of the biggest problems with heat wrap is that when covered in oil it turns into a wick. There have been several Wrx's that have burned up and it is almost impossible to put out the fire on oily heat wrap.

If you do decide to do it make sure that that you seal your heat wrap. I mean use the entire can of sealer on it evern if you think it is too much add more.

The good thing about heat wrap is that it will definitly reduce the temps down there!
