The stock exhaust is 2.5" all the way back to the rear cat after that it steps down to 2.25. I did a 2.5" in/out high flow cat and flowmaster muffler and 2.5" mandrel bent tailpipe and it is perfect I think. I left the pre cats as is and they are still going strong at almost 180,000 miles so if it aint broke... Also I'm pretty sure 3" will be way too large and will probably negatively effect your low end torque a lot and it will definitely be a cop magnet for sure as it will be obnoxiously loud.
