Thermo-Tec Wrap on downpipe?

[supergas]

Installing homebuilt 4 inch on the '96. My downpipe is close to the firewall and I was thinking maybe some header wrap might work here?? I used it on my 454 trucks before and it cut down on the underhood temps alot. Any reason why I would not want to do this here? Thanks for any input.

I've done it and so have several others. I don't have anything negative to say about it, and I don't think I have heard anybody else with negative comments.

No reason you don't want to do it at all. In fact it should help the efficiency of the turbo a tiny bit keeping the heat in the pipe where it belongs.

Thanks for the input I thought it would work fine but have run into things I think will work that caused another problem.

it will cause quicker deterioration of the exhaust pipe due to trapping moisture against the pipe, but it does "work"

With the New HX-40 turbo my down pipe i really close to the firewall. I pulled the down pipe firday on wrapped it with the header rap and then sealed it with a spray on stuff. It dropped the noise level in the cab.

The fine print on most header wrap products will tell you it voids warranty.



That said, Detroit Diesel offers a fully jacketed exhaust mainfold and turbine portion of the turbocharger on the series 50.



We use exhaust blankets for the customers that specify a jacketed exhaust.

long time to hurt the pipe?

won't the muff. rust out before the rap deteriorates the exaust pipe?... . I'm willing to try it for the sound proofing.

That stuff can make the pipes really brittle due to all the heat trapped in the pipe. Its more of a problem with gassers but it still is not a good thing lol. I decided NO on that stuff when I saw a BROKEN header
