Nope I went through and checked for burnt wiring and didn't see anything. I made sure to zip tie everything away from the exhaust. I do have the zzp o2 extension and a stock o2 sensor that I actually purchased from Reptile about a year ago. I do I have SD headers and I have a couple of cm of clearance. When I replaced the dog bone bushings with urethane I made sure to rock the engine back and fourth multiple times and from what I could tell there was no contact with the firewall.
