For any of you who have used j-tubes, I have a question for you. How well have they worked? I am planning on installing a set on my fastback's aftermarket extractor-type exhaust, but I would like to make sure i'm not doing something that will be a constant pain and annoyance. I'm keeping my factory heat exchangers in case I want to restore my old girl to dead stock someday, but here, where it rarely get's below 65 degrees, there not really needed. My primary concern is where the extractor clamps to the j-tubes. Do they have a habit of leaking often? What about the flange welds, do they hold up well? I plan on buying a good quality set of ceramic coated ones, but I ask these questions because, in the past where I used to live (eastern Canada), you couldn't even think about using these....unless you were a polar bear and loved to freeze. I want to use these because of the excess heat the factory exchangers cause in the two front cylinders, and at 120 degrees in July, I need to keep as cool as possible. Any help, or comments either way, would be greatly appreciated. TIA Marc 1967 Fastback Is your boss reading your email? ....Probably Keep your messages private by using Lycos Mail.
