I think this is the tube that connects the turbo to the intake. Is this correct? Whats wrong with the stock part and what will you gain by changing it?
Also, are the cats themselves restrictive? If you are going to install cat backs only seems like this with now be the bottleneck in the exhast and will net only a few horsepower. Is it worth it to change just the cat backs without changing the cats or downtubes?
