just ordered the quad tips I'm gonna run, so now I'm going to buy a muffler, and build it. My plan is to redo the piping from the flange to a single inlet 3in/to 3in muffler with a 14 inch body- Magnaflow 12867 and split to dual 2.5 in to the driver and passenger side.

To those that have done a quad setup, what are the things to take into account? I remember reading that some people had issues with piping the passenger side. Why is this?

also if anyone knows what size is the factory piping is? I haven't measured yet
