A downpipe would be more likely to void he warranty than a tuner though. at least with a tune it takes less than 5 minutes to flash stock. Takes much longer to remove a downpipe and return it to stock.Downpipe would be surfire way to increase on stock ecu with no tuner. Back when vits page was still viewable he mentioned how the spooling and boost would "outrun" the ecu control slightly giving better spool and more boost without commanding it to happen.
