Hey guys. I just installed speed daddy headers and I had a couple questions. When I finished the service engine soon light came on. I'm wondering what the possible causes are. I had to make my own o2 extension so that might be it? And also when I step on it a little bit it gets a lot louder than normal. And it kind of makes a fast paced tickin noise. The more gs applied the louder it gets. I'm pretty sure its not the o2.
