While I think Boling Brothers do a spectacular job with their builds and fab, i sent them a little adjustment to their chassis design that i think should be incorporated.

It is the space allotted for mufflers, I have a full fender chassis so ground clearance isnt an issue but these bars really cause space issues if you were to use chambered mufflers and the car was low to the ground.
all I suggest is to add a small bend downward near the trans crossmember.
