Muffler replacement for stock exhaust ... anyone?

I'm looking to cut-out the stock muffler and put a magnaflow straight-through muffler in its place. Has anyone done this? Is eliminating this restriction sufficient for running a chip? Considering the turbo exhaust outlet is only 2 1/2" (?) it just seems like 4" exhaust would be overkill and a poorly justified expense. All opinions or comments are welcomed, thanks.

I just removed the cat and muffler and welded in a four inch piece of pipe. Sounds great and was much cheaper then buying a name brand!
