Exhaust opinions with current tp

[Deep071]

HI everyone I'm somewhat new to this forum and haven't really posted yet and just had a quick question to everyone.

i have a 2009 nissan 370z with stock exhaust except z1 motorsports test pipes that were installed recently. I'm in the market for a new exhaust and needing some opinions on what you guys think would sound good?

also for got to add that currently my test pipes are making a bad rattle sound and I've looked under the car when it was on a lift and even had a performance shop here check it out and they said it was fine but still continues the issue anyone know what this is??
