I haven't been on the forum for a while. I was just busy, one thing lead to another and I was on a forum slump. But I'm back now. I installed my DC Sports 4-2-1 one piece ceramic header yesterday. I did a small test drive but I haven't really got on the throttle yet. So far it seems good. I heard it would make my car sound deeper but it actualy sounds alittle quiter. Alot different from when it sounded with my intake and catback. It makes a kind of huming sound now. Is this normal? Also I have a question about installing my lower tie bars but I'll post that on the suspension section.
