questions about catback exhausts, downpipes and midpipes
 

hey i am about to order a catback exhaust and maybe a down pipe. I was wondering which is better the hks carbon fiber hiper exhaust or the apexi gt spec. I was also wondering if you put in a downpipe but know mid pipe well it be emissions legal because on other cars that dont have a midpipe if you put a downpipe it becomes off road only like toyota supras for example and also what if i dont put i a down pipe but a high flow catalytic converter will that still make it emissions legal

you are correct as far as emissions. midpipe=no pass. I saw the hks on a FD last week. That sounded pretty good, but loud for my taste.
