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?

Test pipes are the best bang for the buck. And yes, you're gonna need a tune.
