I'm sell the exhaust that came on my 99 nsx when I bought it five years ago. Recently when turbo so this exhaust has to go. I was told it's a GT ONE F1 exhaust at the time I bought the car but not sure how to confirm. I love the sound of this exhaust and it was very liveable but when you got on it it was awesome sounding. I do have pride resonated test pipes on it which livened it up more. I can sell the test pipes separately if needed. I'm asking 1500+shipping and fees. I have a short sound click I'll try and post or send to you. Thanks for looking. ****test pipes sold****** still have the exhaust.
