370Z DFW Exhaust WTB/WTT

Bruce AaLee

Hey guys,
My name is Ali, I'm new to these boards as I just sold my C6 Corvette and purchased a 2009 370Z Touring Sport 6M. It came with an Invidia Q300 Exhaust and non-resonated test pipes. The car feels faster than the new 2010 Nismo Z and base Z I drove at the dealership, but the exhaust is too loud for my taste.

The Q300 by itself is one of the best performing exhausts made for the 370Z.

However when paired with non-resonated test pipes, this exhaust is loud and raspy.

1. The first thing I'm interested in doing is buying or trading my test pipes for Catalytic Converters:
Berk/Stillen HFC
Stock Cats

2. I'm also interested in buying or trading for performance exhausts that are known to be on the quieter side:
OEM Nismo Exhaust
Stillen Exhaust

My car has 17500 miles on it, not sure when the exhaust/test pipe was put on, but it is in good condition. The test pipe has long tubes O2 sensor tubes and my car does not have any CEL issues. Depending on what is being traded, money will have to be part of the trade. For example, I'm not expecting to be able to trade a test pipe for a HFC without paying something on top.
