Lexus IS300 magnaflow muffler

Replaced stock muffler with magnaflow. Has a 3" inlet wit a 4.5" tip on the outlet
(UPDATE) For all the folks look for a muffler number, i didn’t know about it since i had a independent shop do the work, just told them to put on a magma flow basically. Also sold the car years ago. If i ever find the bill for it ill see if it has it on there.
