Here's the process of what I had to do to change the 14" Magnaflow muffers out for the 20" Dynamax Super Turbo mufflers:

I cut the old mufflers out pipes. I then cut off the hanger rods and welding them to the new mufflers. I also had to cut off the new muffler's rear 2.5" ID pipe stubs and weld on 2.5" OD stubs in order for them to connect to the Magnaflow tailpipes.



Used a little trial and error to make sure I cut out the correct length out of the exhaust pipes between the X and the mufflers. I then did a mock-up using clamps to make sure it was perfect. Even put the tailpipes back on to make sure I didn't change anything there. Once I was satified, I tack welded the joints.





Welded up, ground the welds flush and painted all the welded areas.





Back on the car and done. Came out great. Quite a bit of work. Spread it out over 3 days.







Actually got a little sore doing this work. Felt good to get back into car working shape!
