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 had a flow thru muff when i put on my exhaust and i just took it off last fall. It wasn't worth it. Just go no muff, you'll like the sound.
