turbo ppl come in

for a turbo, pretty much the bigger the better. 4 inch is the standard now. Most people are hacking up duramax exhausts, I just ran a piece of straight 4 inch with no bends, just a little "crick' where its welded to the muffler to keep it off everything. Im running the Big cased magnaflow muffler, 4 inch as well.
This is 3 inch, but its now, or was 4 inch. Except no bend as show,just a long piece of 4 from the downpipe to the muffler, easy to remove as well. V bands FTW ( picture just for reference)
