Yeah get a base. It still comes pretty loaded but no Navi, no touch screen, no pony projectors.
Whipple kit is supposed to be 700hp with an optional 5 year/100,000 mile warranty. Dont quote me on the warranty. I will believe it when it is posted on the site.
You get the Pony Projection l9ights on the base. It is listed under the 300A package for the Base 2015 GT
