OK guys.

Lets say I wanted to keep my stock exhaust but swap out the muffler only. I think the tubing is 23/4 inch. I might be wrong. What is the loudest magnaflow I can buy that will fit in place of the stock muffler. I plan on doing this at home, so the fit is going to have to be exact.

you will have to add a ext. to any of the magnaflows , i put the 4x9x18 and my shop installed bout a 14 inch ext to make up the difference
