2004 RX-8 Touring, time for mods
 

Have a 04 that I am working on. I have been researching ehaust system/header combo's to which seems to lead to Exoticspeed. I like the look and sound, what I have read says it is quality, and was wanting to know if I am picking the best option. Is there anything else to look at? I am after power so it can be super loud and that is okay with me. Also, if it is the right choice where do I pick it up from, I have found it on eBay from a shop, and of course on exoticspeed.ca. Thanks for the help in advance.
