I know some of you guys are running this muffler, just wondering if it was a straight up cut the old one out n put the new in place? Or was there a lil fabbing needed to connect to the stock pipe?

My plan was to keep all the stock pipe (front n back) n replace the muffler only...

I believe that's how most Magnaflow mufflers are. Just cut out. Weld in and go.

I had bad problems with the magnaflow muffler. I went through 3 of them cuz they kept having baffles come loose and rattle and it drove me crazy, i switched to a flowmaster and havent looked back.
