i am getting a Nismo S-Tune Exhaust. Its about 6-7 months old. it has a couple of scratches on the mid pipe and the Y pipe and im getting the adapter so it can fit on my infiniti g35 coupe. I am buying it for 750. Is this a good price? Should i worry about anything? how do i make sure its not a replica or anything? Ill appreciate if anyone can give me some hints or details for my buying. Please and Thank you

 

that sounds like a decent price. not amazing, but acceptable. i believe its about 1200 new. i may be wrong but it shoudl say "nismo" on the tips if its legit. i'd go with it.
