I know some of this has been discussed in other posts, but I am still a little confused. Frome what I am understanding only the stage 1 and stage 2 stillen SC won't void my warranty. So I am think of going with the stage 2 SC, Nismo headers, and Nismo exhaust. Is there anything I need to add to setup that won't void my warranty. I just became an owner so I have read a lot of the stuff posted here.

 

It depends on your dealership. Some of them are cool with aftermarket parts while others will give you a hard time. If you have bolt-ons then you shouldnt have a problem. If you have a built motor with a TT, forget about going to any dealership for service. Your parts should be ok.

 

The STILLEN Supercharge is not covered by your local NISSAN dealer... It has its own 3rd party warranty that is available for purchase seperately... If you purchase it, you can bring it to any authorized NISSAN Dealership or service center and the 3rd party company will pay for the work...

Although, the 3rd party waranty only covers the supercharger and any part that fails directly caused by the failure of the supercharger... If you have another problem that is not directly related to the supercharger, it should not be a problem...

You could just get all nismo stuff (only s-tune). Or be sneaky and get stealth mods like a lighter clutch and flywheel and LSD + 3.9FD...Or even lighter wheels. The wheels and drivetain mods wont give you more "power" but they will make your car faster, and should keep your warranty safe.
