Hello, Iam a new 2013 z owner. Iam planning on doing some bolt ons at first and FI in the future. I previously owned a 2001 Mustang that put down 610rwhp, so I am experienced with modifying cars just not a Z car. I was trying to decide what would be a good (not to loud) CBE...and I was also wondering about voiding the warranty, not ready to do that since the car is new....Any thoughts or coments would be greatly appreciated... My goal is 300+RWHP without voiding warranty if posible...
