I've decided to replace my 2 1/2" Magnaflow mufflers with Dynomax Super Turbos. I want something a bit deeper and quieter.


The issue is the outlet of the new muffler is the same OD as my existing tailpipe. What are the best options to make this connection. I don't want to weld it since a) I don't weld and b) as soon as it's welded I'll need to take it out for some reason.

Options I've seen

Use a band clamp designed for butt joints
Use an exhaust pipe expander and stretch the tailpipe making a typical lap joint
Use a coupler and clamp both sides

Others?
