So as I am wrapping up the 1-5/8" heat exchanger project I am curious if there would be a demand for 1-1/2" or 1-3/4"? I have had a few inquiries and wanted to gauge interest. I can honestly tell you I can't sell them for 1500 like I did for the 1-5/8" as I basically broke even.. I think I can make it work at 1700 to 1800 for the group buy if we get enough as I would have to buy tooling for the bender that costs 4k alone. Let me know who is interested.. Retail will be 2200 just like the 1-5/8" so those who are interested let me know now.

I might be interested the other way...1-3/4"

I would definitely consider that as well..

Ben, you would then be making 1 1/2 headers with out heat also. Mark

Yes correct..

As much as I want a set of these for my Six, it just has to wait until my car is back home in my garage.
