Looking for some help with my Lancer GTS. It's the 2009 2.4L 5 speed. I'm looking for not installing a whole new exhaust (from the cats) but rather just a new muffler and tip. Now, my question is, what dimensions of muffler will fit? I really like the sound of Glasspack's. So, whats the inlet size and such? Anything I should be wary of while installing?

Sincerely, a confused teenager.
