No plans for a tune probably until the warranty is up.

EDIT: Also I have the torque app with OBD II connector..not sure if you are familiar with that. What should I monitor after installing to make sure everything is running correctly?

I think with a CAI and short tails.. you would be fine .. if you do anymore you would prolly need a tune

The AAM Resonated Short Tail exhaust kit is a excellent quality and well designed muffler delete. I have installed five AAM Short Tail exhaust kits and they have excellent fitment on the 370Z platform. I have never seen or heard of any negative effects from installing a AAM Short Tail exhaust kit on a 370Z. The AAM Short Tail exhaust kit will add whp/wtq to your 370Z if you install this kit. There is not enough back pressure lost to make you loss whp/wtq. You will be helping your VQ37HR engine release exhaust gases fastest and more efficiently helping your VQ37HR engine breath better. The whp/wtq gain will be miniscule though. You will benefit from a better sounding 370Z. I am not biased at all in my opinion I think the AAM Short Tail exhaust kit is one of the best sounding muffler delete kits out there for our 370Z. Also the exhaust tips on the AAM Short Tail exhaust kits is very appealing on our 370Z’s as well.

As far as needing a tune I have seen my share naturally aspirated Z’s dyno over the years and you will not know any conditions without using a wideband. For just a cold air intake and exhaust installed your engine pcm will compensate and adjust for these modifications easily and conditions will not be dangerous for your 370Z to constitute needing a tune. If your Z is under warranty and you do tune and your engine PCM did fail you will end up replacing it on your own dime. I would wait to get tuned if you decide to.

Quick,

Thanks for the responses. I decided to order the short tails..just a tad disappointed I'm going to lose the engraved "Nismo" lettering on the stock tips! Once I'm confident and happy with the setup I'm sure I can have the stock tips put on.

Im not even running a CAI, so it should not be an issue at all. Not sure if you are familiar with the torque app for android...but for peace of mind what vehicle stats should I monitor post install?

How do you like them? I'm assuming you installed them?

Did you lose any low end torque?

Thanks
