Unfortanatly I'm not too familiar with the h/x pipes. Is it a weld job or a bolt-on for the exaust? I am assuming i will still need the MIL eliminators. And if i get a h/x pipe, will i still need mufflers or will that make the difference? P.S. i am mostly just doing it for the noise, but i do want the car to sound as good as it can without having to buy a whole new system. Thanks.
