Planning on changer my muffler to a Flowmaster Delta Flow 50. Upon ordering, I was asked what size pipe, offset in/out and overall muffler dimensions. Just wanted the muffler and have a muffler shop install it. I have a 4.2 S/C 2wd auto. Does anyone out there know the dimensions I need? Thanks in advance for your help.
