Hey guys !
I noticed recently that my focus started hissing whenever i pressed the gas pedal and started losing a lot of power so i thought that i have an exhaust leak and i checked and found out that it’s leaking from this area i dont have the time to fix it and i have to do more than 200 miles with it tomorrow will it harm my engine in anyway? And can it cause a huge loss of power?
Thanks in advance
