We received this car on Monday of this week. We will be doing all of the prototyping in house in our NY facility. We plan on making a 1 3/4 x 3 and a 1 7/8 x 3 then 3" back through the x-pipe then stepped down to 2 1/2. We will also be releasing a 3" all the way back version in the near future.I will post up picks as the R&D process takes shape. Here are some of the car.
