Exhaust

My lowly 1st gen truck now sports the the wastegated exhaust, elbow, and dowpipe from an ISB. The downpipe comes to about an inch from the firewall now, and I'm absolutely certain that when towing heat is going to cause trouble.



I'm not particularly interested in turbo wraps, as I think the higher heat buildup in the turbo housing will simply get transmitted to the center section, with the bearings and oil catching the damage.



I'm just wondering if anyone has wrapped or otherwise insulated thier downpipe... If so, what did you use, did it work, was it expensive, and even more important... how much of a pain was it to install?



I looked at header wrap at the local parts house... and what they had looked pretty cheesy. Even some sort of thin insulating stuff for the firewall would be fine with me, I just haven't found anything yet.



Here's the image of the turbo and downpipe...

There are quite a few of us who have used header wrap. I used the DEI (check my sig) brand and found it to work out quite well. Afer I wrapped it up I painted it with their recommended coating to help keep the heat in and the moisture out. All in all I am very happy with it.



My original intent was the same as your's, to keep the heat away from the firewall, but after reading more (and getting some feedback from Hemi-Dart) about wrapping the downpipe, there is more to gain than just protecting the firewall.



I used about 2/3 of a 2"x50' roll. This was on a 4" downpipe. Total cost for the wrap and the paint was ~$50 from Summit.



Hope this helps,

PowerWagon, I am also running header rap on my 4" down pipe. I took the down pipe off wrapped it tightly and then painted it with the paint that i got with it. It seems to work well.
 
I had Doug at Wentland wrap my setup (same routing as yours) with insulation from a Powerstroke downpipe:eek: I've gone through a summer of driving and towing and it works quite well.

fascinating. I'll have to see if there's any more over there to rob from them. :D



I think I'm going to line most of the firewall with a sound and heat insulating aluminized pad. It's not expensive and it looks kinda cool.

I insulated my down pipe with the pads that came with a Banks turbo kit for a 6. 9 Ford. The pads are quilted aluminum faced and filled with a ceramic fiber. They are fairly thin and can be formed easely around the pipe, slid down into position and secured with wire ties. The ceramic is a very good insulator -- my pipe is close to the firewall and the plastic air cond. box. They have been on since "92" and still work great. I think you can buy them from Banks as replacememt parts.

I used the aluminum faced insulation under the carpet and in the door panels. There was a reduction in noise and it seems to stay cooler in the cab in the summer. It was quite a project to remove the carpet but worth the work. I even found some "stuff" I thought had made it to another demension! The door panels came off fairly easily and I pre cut and fit the sheets in 2 pieces then glued them in place. Hope this helps.

Happy trails

When we were installing the new turbo housing and downpipe, I bumped the rubberized sheild for the heater and large chunks of it broke away. The whole thing is brittle and falling apart. Since the dealer quoted me nearly $300 for a new one, I've decided that something else is just going to have to do.
 
PW any NAPA sells heat resistant products, or you could call the NAPA in valley center ca. and get what you are looking for , they are a distributor for the product, wraps ,foil backed products etc.

also Thierry in vista ,ca is parting out a d350 , give him a try for what you need.
 
The circle track guys have a ceramic pads in different sizes to deal with the heat. If you'll give stockcarproducts.com a look you shold find them. Not real sure about the $$.

I used the whole 2"x50' roll on my downpipe to just passed the lower bend. if you are going to be in Tacoma on the 2nd you can see it there.
