That'* the car you want, others will trip a SES light, as you already found out.
Removing the res can make your car sound raspy. Some times cars sound ok, but other times, not so much.
Anything you do that changes flow will change the sound. Rockers or cam will deepen the sound, a Plog or better yet, headers really changes the tone. A lot of members use the flowmaster or magnaflow series 80 muffler, or series 40 if you have duel mufflers. Changing the size of the pipes isn't worth the cost or effort, you have a 2.5" exhaust, leave that part alone. The bigger cat is worth it though, get the 3"
