I have a '17 440 with MPPSK..I was also looking at VRSF Catless Downpipe (As amazing as MPPSK is, I am looking for even more aggressive sound) so it seems like catless is the way to go for me, but I keep hearing how catted is a good idea too? Seems like comfort mode normal driving should keep the catless dp with MPPSK pretty tame? and then crazy in sport..
What do you guys think?
