New to the forum. Just bought a certified pre own 2013 Si. The car only has 400 miles on it now. I am interested in doing a couple things to the car but don't know if anybif them might void any warranty I have. I would like to add an intake, lowering springs, and a catback exhaust. Please let me know if you have had anybexperience with this or have any thoughts. Thanks!

 

I would wait until the warranty expires.
