The title says (KSA) Greddy Exhaust on an 08 3.5 sedan. In the comments it says its a Greddy coupe exhaust that has been shortened to fit the sedan. Whatever it is, it sounds a lot better than the coupe exhaust, it sound a lot like a Z to me.
What do you guys make of this? (The guy hasn't responded to my message)
KSA is referring to the Kingdom of Saudi Arabia. To me it looks like an EVO2 exhaust. Just look up some EVO2 on altimas on youtube, they look almost identical.
