Aftermarket exhaust tubing size question

Does someone running an aftermarket exhaust know what size the tubing is? I looked at some online and the tubing looks like 2.25 while one listing said 1.75!?!

I wanna get something going on mine but wanted to collect some info first.

The U-bend that connects to the oe "S"muffler is 1.75" Size you need depends on engine size & RPM range you want to maximize torque.

My mid-cat delete pipes were manufactured with 1.75 pipes on my 04S.

Most come with a reducer pipe to transition from 2" to 1.75"
