Hey im new to this forum, got a 2009 base 370z with sport package a month ago and am definitely interested in the top speed exhaust. I was going to get the aam shorties but they are 400 dollars sounds good but i rather get this top speed. Could anyone tell me if putting an exhaust will void my warranty? Car has 35k miles and i extand to 70k. I have heard many diff answers that cai is ok but exhaust woukd void warranty. Anyone know for sure?
