i recently threw a Yoshi TRC slip-on, along with the hotbodies undertail on. i have a 08 r6s. sounds great rides great. my bro put a kr tuned full system on his 04r6, sounds just as good.
as far as looks? its all what u want. start usin google images. ask questions on forums if you did the research and still cant find or understand an answer.
just understand we here 4 each other but dont waste our time. other than that welcome to da club
ps-best thing u can do for opinions on exhausts is look 4 reviews on purchased exhausts. realize that u have an 09 so its not gon show up in many options or drop-down selection menus just yet, but 06-08r6s and 03-05r6 shit WILL fit, accessory wise.
