The downpipe goes out the turbo and into the cat (provided there is one). You wouldn't bypass the cat and leave it still in there cuz all your exhaust will run through the downpipe. So if you plan on bypassing the cat, just take it off.
thats what im sayin if the down pipe gose to the front of the cat through the cat and to exhaust or just to the exhaust where the back of the cat was you would not have a cat anymore down pipe would just ot straight to exhaust any one know what the turbo performance kit dose?
