if i were you i would get the hfc's tomorrow. such a great mod for the money. i would do research on which brand you like. i chose stillen because stillen is always quality and its made in america. they added close to 15 whp on my car. not as much power as test pipes but always stay away from the test pipes unless youre running a twin turbo setup. i would highly highly recommend the hfc's to you. get them and let me know how you like them!
