515ps with piggyback I can understand but +20 for dp's and + 20 for drop in filters?
DP's seems reasonable but the drop in filters? Also I always assumed you couldn't just add performance numbers. Throw on 2 more stickers and you've got a 600+ beast  |
Catless downpipes could easily add 20hp. Getting 20hp from filters is a stretch even at the top of the powerband, unless you also remove the carbon filter at the same time which is very restrictive.
