Hey everyone. I have 2 questions about Magnaflow exhaust for an 03 cobra. 1) Will a different brand of X-pipe (bassani for example) be able to link up with the magnaflow catback system? (Probably a very stupid question, but I'm a tad ignorant.) and 2) Where is the best place, shop or online, to purchase Magnaflow? I've seen sites from $320ish to $479. Any suggestions? Thanks for your time.
