Hey JC what did you wrap your exhaust with? how wide was it? how long? how much overlap? what brand? I know you told me some of it at BusNUSA last year but i should have written it down. :>) | ||

Thermo-Tec and DEI enterprises sell it in 2" by 50 foot rolls. It is a woven fibreglass like material sort of like webbing. You wet it before installation and wrap it around what you are going to insulate. at the end, you secure it with a hose clamp. Summit racing as well as many speed shops sell it. Can be ordered online. I have personally used it and it works as advertised. Am satisfied with it. Couple of things- if the pipe is going to be subjected to any road salt, you will need to seal it or protect it, otherwise the salt lays against the metal and will cause rapid deterioration. Also, some have said that the concentration of heat now in the covered pipe can cause metal cracking in the long run. Of course this, I believe is experienced mainly in the thin pipe used in headers and pipes on automobiles. It definately improves performance. By retaining the heat in the exhaust, it will draw better, just like a hot chimney with a coal or wood fire. Turbos will also spool up quicker. These improvements are going to be modest or subtle but should be able to note a slight improvement. Plus the main benefit of heat reduction to surrounding areas. | ||

Hi Ed, how have you been? I'm thinking about going to Bus'nUSA again, maybee I'll see you there. I think the wrap was DEI. It works just like John says. Easy to install. I secured it with stainless steel wire. I overlapped it about 1". I can't tell about an increase in performance, but it sure reduces the engine compartment temperature, and the bedroom above. You can put your hand on the turbo and exhaust anytime. I can't remember the cost, but I did the turbo and about 3 feet of 5" pipe with 3 rolls. The muffler with the same material, only foil backed and in a sheet about 3 by 4 foot, also secured with wire. I want to do the exhaust manifold soon before we get going this spring. JC | ||

Oh and Ed, the whole thing was less than $200. JC | ||

Thanks JC and John. Thermo-tec and DEI, Summit and Jegs, were all part of what i was looking at. Thanks for confirming what i thought i remembered about it. Hope to see you again at BusNUSA JC. We are planning on being there and at the Rally at the Caverens too. |
