i just bought a apexi N1 and i have the racing beat true duals on my car right now and im looking to sell it from the y-pipe back, so y-pipe and the 2 racing beat muffles and you would need to complete it is the presilencer and the true dual header those 3 pieces alone are like over $600 brand new and you can ask anyone they have not been on my car very long at all. They will still give you a good stock look but trust me they are worth it with the sound they make and the HP gain i got around 20 hp on my stock N/A with the full dual system. If your interested i am willing to sell for $400 obo which is a really good deal just work with me on it and ill try to give you the best price but thats a good chunk off the original prices i mean the 2 mufflers themselves are $500 together so just how you look at it i guess. If your interested hit me up with a PM and we can talk about it.
