Hi Just purchased my car with the following mods. RM racing intake, Comptech headers, RM racing exhaust. I don't know which models, or if there is only one that fits on this year. That's my first question. Second one is I'm not sure if I'll get use to this sound. Can I put the stock exhaust on or do I have to trial and error it with different ones. I also can't find any related sites to RM racing products. Any help with any of these questions would be greatly appreciated.
