Its too tight of a squeeze to fit, I tried sanding the tbr slip-on slightly but itll go in about a cm and just get stuck. Other than using a dremel is there a better way to make it fit loose enought that I can turn it during install and clamp it up? Pipe widener perhaps? Have a muffler shop do it?

They will be able to fit just fine with a little tweaking I just dont want to do any major damage.

 

Solution I went to a local muffler shop and someone widened the pipe for me. Put some RTV silicone and clamped it now its perfect!!!
