I know I sound a little paranoid, but if anyone could shed some light on this, Id be very grateful. I just got my car back from the dealer after having the transmission, throw out bearing, clutch fluid, and rear axles replaced under warranty due to a faulty input shaft, and clicking in the rear from my axles. I just washed it and waxed it and want to put my first mod on it, and after hearing the AAM short tails, its the exact sound I am going for, I am just afraid of causing damage due to lack of back pressure.

That's a lot of things that went wrong with your car. I've never had a problem with my 08 HR Z, and it was drag raced all of it's life. I'm considering a 370z as my next car. I hope problems are not common with the 370's.
As far as your car, this is what I would recommend. Put test pipes on your car, plus the short tails, change to 4:08 gears & get a good tune. With the gears, you'll won't feel a loss of TQ & the car will be super quick & fast. With traction & good shifting, you can have a mid 12 second car. You'll gain a ton of H.P. & the car will be loud as hell.
