Hello Im from central PA . I haven't yet purchased a RDX but I'm researching and will be soon purchasing one. I'm new to Acura but not new to Honda. I had a 07 Civic SI with K20z3 which is in the same family as the K23 so Im very familiar with the I-vtec motors and hondata. I currently have a 03 kia Sorrento that is being traded on in for me to get a Acura Rdx . Talk about a Upgrade lol. Kia is ok but I know Honda quality so the kia Sorrento is nothing in comparison to a Rdx. My 1st mods will be HONDATA and then I'll probably change downpipe and then exhaust. Any exhaust brand you recommend ? Or downpipe?
