OK, let me be clear. The GTM/Stillen kit is the greatest thing since the invention of the automobile whilst the Stillen/GTM kit is an utter piece of crap, not worthy to wipe my posterior with. The Stillen/GTM kit is constructed of the highest quality material where as the GTM/Stillen kit is just thrown together with whatever they had around the shop that day. The GTM/Stillen kit will net you around 500 hp easy but the Stillen/GTM kit will actually rob you and leave you with less power than stock. Don't listen to the GTM/Stillen fanboi's, they are paid to lie about their product. If you don't listen to me, you are probably a nitwit/nin-com-poop and don't even deserve the quality associated with the Stillen/GTM kit....good day!
