A friend of mine had shorties installed on his 2011 challenger and the place that installed them striped one of the bolts in the aluminum head. Now he has a small exhaust leak. He is taking the car in for an upgraded cam in a few weeks and would like to wait til then to fix the leak. My question is will driving the car with an exhaust leak on the #1 cylinder damage the valves or anything?
Thanks

 

Nah, it'll just be a bit annoying and could possibly throw a CEL depending on the reading the O2 sensors get, but he'll be fine
