My understanding of a test pipe with a resenator was that it opened up the exhaust making it flow better as oppsed to it hitting a plugged up cat. I was thinking about getting a test pipe to open up my exhaust but then i guess id be a gross poluter. You know what though as long as i put it back on before i go to emissions i'll be fine, even though i am killing the enviroment i might just see a small highend increase. Not sure if i'm gonna do this or a high flow cat. But i'll probably do a high flow cat because then i don't have to mess with my exhaust every year.
