Doing X-pipe and secondary cats - question?
Going to replace the resonator with an x pipe and remove the secondary cats
Question is? 2.25 or 2.5 when ordering x pipe, and 45 degree pipes? Are those 45 degree pipes ok?

2.50"
Yes, 2.50" for both. So you are replacing the resonator with the Mandrel bends and the x-pipe with the 2nd cats 
also checkout the seller named mandrelbends. Go with the stainless steel x-pipe.

POA replace the rear cats with a 2.5 X-pipe, the closer to the Engine the better.
