ERA has 2 under car exhaust options that will work. There is enough clearance. The side pipes hang lower than the frame rails so you should be all good with an under car exhaust. Maybe that is moot now and you are going with pipes..... I admit to skipping the last 3 pages of this thread.
The inboard brakes work well and save you a bunch on the budget for other items. As Peter told me when I was asking about converting mine to outboard brakes.... the rear brakes are not as important as the front. Get the larger front brakes. They are the ones that are going to stop you anyway.
Love the sunburst wheels. If (when) I build one it will have sunburst... I guess I could get a second set for the current cobra..
