i cant find a flowmaster 40 series for '05. i've been told to order the kit for the '03 and that it should work, any help?

 

Have you called Flowmaster? They should have the best information about what their products will fit and if they have something that will work for you.

 

I don't think the exhausts changed at all in size from 98 on. Your tube sizes are 2.5" in/out. As long as your in/outs are that size it shouldn't be a problem.
