I bought the black widow with cf a few weeks ago to my 2008, the workmanship quality is very good, welds are outstanding. Experienced no problems with install, good fit up, all stainless steel headers. No adjustments required to Ecu or pc, it's approximately 15 lbs, paid $517 to Hawaii, free shipping (delivered within a week) free flowing power, can feel difference, did not do or will do a dyno tune. Ok, the negative, the exhaust sound isn't exactly what I wanted, although it sounds way better than stock (had the yoshimura r77 duals), not like the Yoshimura full exhaust that has a real deep throat & loping sound but higher price, also, the customer service response time is a couple to few days, sometimes none response (via emails). Also, if ordered, you will need to buy your own gaskets, the ones shipped, do not fit. If your not looking for that deep throat or loping sound, like I am, it's a great buy & recommended.
No problem. Good luck & Aloha.
