ok i got cobra exhaust for free (its a 99 car) now i kno it needs to be adapted for my car. but i dont kno how and i dont kno if it worth it. is it the part that goes over my soilded rear axle? or do i need alot? and the guy said i need a kit to make the exhaust installed to my 2003 v6? he said he could not install them on my car? but if i get gt exhaust it will only cost 60$ to install.
