It will perform exactly the same way as any other downpipe, brand will not matter when it comes to performance

Aftermarket downpipe are not smog legal
You do not need an exhaust

catless downpipe will remove the restriction caused by your stock cats so you turbo can make more power with less stress (high flow cattted downpipe will not completely remove the restriction, it will reduce it significantly)

Downpipes will also make the car louder
