they have numbers up by the tips so how do i determine how to which tip will fit my stock exhaust pipes

Get under the car and measure the inlet and outlet connecting pipes outside diameter and the length of the stock muffler, correct?, no other way.

also one last question could i put any 3.8 liter cold air intake in my car?
