The end caps are rusted off of the magnaflow res its hardly worth scrap. Ive re welded them back on twice now. I was planning on getting a MBRP 30" resonator with a 3" in/3" out and run most the way down the center of the car from the down pipe back getting rid of the magnaflow res then adapt to the 2.5" piping further back. Then I rode in a car with a ZZP 3" catback that had a 30" res on it and it was the loudest miserable POS ever. My car is not even all that loud I just wanted it to be a little more stealth and 0 drone for those 1000mile road trips.
