Got a quick look today.They removed spacers on the risers and carb and it actually looks like it takes up a little less engine compartment .I didnt get a chance to ask bit I was lead to believe that the spacers under the risers are what made this "dry" exhaust. I have been dealing with the owner and sold me on the "drop in " engine so I dont think he is gonna try to ramp up the cost of the mods since he actually believed it was a drop in.Also my engine compartment access for the switch over could not have been any better making it much easier for them.When the tech first looked at my access he turned to me and thanked me.I included a pic of my access.Charlie
