So im getting a really quite muffler to replace my tail pipe, with NO muffler. The muffler i used to have was a ripoff with just a straight pipe, so it was really loud. However it was a 2.5" catback. The muffler im getting which is a stillen axle back is 2.25" will this bolt up to a 2.5"??? thanks guys!

 

try it if you have it. most flanges are the same but they can be clocked at different angles.

 

It should, I had a 2.25" twin loop hooked up to my 2.5" piping and it was the same...as long as it's for your vehicle make the flange should be the same.
