So I’m a bit of a dumb ass and cut my mufflers off myself about a year ago…. I’m very much a hypochondriac and have been dealing with some weird symptoms past month… I have been having muscle twitches all over body, and constant muscle cramping/ tightness…. I started to think … maybe carbon monoxide has been leaking into my car and I have cause brain damage over time … the pipes end right at the end of the rear wheel… I usually drive with my windows down which should lower the chances right? Do you think carbon monoxide could leak into my car from where the pipes end (I attached a picture) Are these symptoms of carbon dioxide poisoning to begin with? I don’t know please give me some insight!
