426-450 pipe

This is a dumb question but do the mufflers for the 450 fit on the 426 midpipe or is it a diffrent diameter? :thumbsup:

I searched on here and I only found that the header is a diffrent diameter but does anybody know if a 450 muffler will fit on a 426 mid pipe? Thanks :thumbsup:

The subframes are different, and, if you're talking stock stuff, the 450 muffler and midpipe are one piece. Cross fitting has been done with some pipes, but it takes some tweaking and doesn't work in every case.
