yeah, youre talking about a Y pipe which does exactly that, it takes your single exhaust and makes it into 2, but like the guy above me said if you do that, youre going to actually make your car slower, and also it prolly wont sound that great unless you pull the cat off which is highly illegal and you prolly will get busted for it, so in my opinion, save your money, and buy an HKS full exhaust, and that should be more than you could ask for
