Just bought the OBX 4-2-1 Header so....
I just purchased them today, and I will probably install them like next weekend, but heres my question. How do I make them not so loud? I've been reading a lot of the posts on here about them and what not, but I have not been able to figure out exactly what I should do. I still have my stock exhaust on my car, so do I have to like get a cat back exhaust, or can I just buy a new muffler? And where would be the best place to buy whatever it is I need? Help would be awesome guys. Thanks.
