Hey Guys,
I am thinking of fabbing up some headers from 304 stainless. These would be equivalent or better than the Supersprint units currently avail for $3000+. I have had extensive background in motorsport fabrication and welding. These would all be fully Tig welded and Mandrel bent. I am trying to get a feel for how many sets I could actually sell, and if it would be worth my time to do so. Please feel free to post opinions and interest. Also, please interject any features you would like me to explore in these new units. The total cost on the headers would be around $1800 per set. Each set would take approx 50hours of labor to complete, so this is VERY competitive when you consider my time and materials as well as the cost of my equipment. The high flow cats pricing is TBD as well as the x-pipe. Thanks for your time.
