hey everyone so i just want to know your opinions on my next upgrade, i own 07 350z with 71k miles i have a full hks high flow cat back exhaust with dual cold air aem intakes, i also have Megan racing test pipes, would i see alot of difference in hp and tq if i install them on and also 0-60 times? im debating on whether selling them or installing them on, also would i have to get a tune once i install it?

 

Your car will blow up and the check engine light will come on. Then the EPA will send a SEAL team to your house for removing the cats and therefore harming the environment. Your car will then ultimately me hauled off as government property and placed into auction. Think of the trees.
