Alright team I have a bizarre question and since it's night I unfortunately can't add pics but I will add them tomorrow! For now please try to keep with me. I noticed the car starting to sound funny and really ticky about a week ago and all of a sudden it got loud and threw a code. I don't know how to check the code since the exhaust is modified and I fear the dealership. But I put the car on the lift and I noticed I'm missing a bolt on my passenger downpipe. Could that be the reason to the code and the noise? And if it is! Then how do I go about replacing that bolt? Thank you so much in advance the car is a daily driver and i need her running back to normal!
