I went aftermarket custom. I have a turbo muffler placed up and out of the way. The tail pipe is 2.25" and the front pipe is 2.5".

I have had the system for five years with no problems. It is quite but that is in part due to the turbocharger ahead of the turbo muffler.

At some point I plan on going 2.5" out the back.

I did not want to deal wth the factory setup at all.
