Some have said that it can shorten the life of the pipe as the heat cannot escape. Not sure on that one, but the car has only done 9000 miles in 5 years. So it dosnt get driven enough to worry about that. The question is, would it be a good idea to wrap the dump pipe in heat wrap from my turbo down to the exhaust on my XR6T?

But wasnt sure as it seems like the temps are a lot higher on turbo cars exhaust, its all sort of concentrated in one area I guess. I mite grab some next time im at rice barn. At least I will only have to remove the rear heat shield to get it on. Link to comment Share on other sites More sharing options...

Joins tend to crack very quickly. Link to comment Share on other sites More sharing options...

Wrapping the dump/front pipe in theory reduces turbine efficiency; by how much who cares I can't pick it.Wrapping of the dump/front pipes is to prevent it cooking everything around it.If you have coolant hoses around near the dump its a very bad idea not to have some form of heat shield or wrapping of the dump. Glycol sprayed in a fine mist (caused by a pin *beep* hole in a coolant hose) is extremely flammable. It will send the engine bay up in flames.
