Not sure what's up with my original post, but here is all the info again.
I just sold my 370Z and I have an Exoticspeed catback exhaust and Berk Technology high flow cats that came off the car.
I bought the Exoticspeed about 14 months ago... it had 500 miles on it. I put an additional 4000 miles on it. It is in great shape. It is a true dual exhaust and it sounds deep and exotic. It sells new for $1499. I'll sell mine for $799 if you pick it up near Philadelphia, PA.
Here is more info on the unit:

The Berk cats have 4000 miles on them. I bought them new 12 months ago. The sell for $549. I'll sell mine for $399 if you pick them up.
Here is more info on the cats:
370Z/G37 High Flow Catalytic Converters - Nissan 370Z/Infiniti G37 - Berk Technology
If you want both the exhaust and the cats I'll sell the set for $1150 if you pick them up. The set sells for over $2000 new. You can get my gently used units with less than 5000 miles on them for almost 45% less.
Thanks for looking!
