Hi there,
It would not be a problem to build the car the way you are suggesting. The only down side to it would be the time frame. The silver car with the under side exhausts ,on our web site, was custom built for a customer who wanted a "Gentlemans Racer". Apart from the underside exhausts , the car has an A/C , Hard Top, and Torneau cover. The development of the A/C was probably the most time consuming part of the job.
If you would like to contact me directly I will be able to give you a quote with the relevant time frame to build a car to suit your needs.
