Gains with downpipes vs flange adapters?

[MacK88DO]

Hey guys, first time poster. Been lurking for a couple years but finally brought home my 2018 SCREW Lightening Blue as surprise from the wife for Christmas.

Been watching the threads and various tuners but I’ve noticed that no one advertises increased gains with downpipes installed with tune vs just tune? Seems like the easiest exhaust based gains to be had are the turbo flange adapters which are much cheaper and emissions compliant. Does anyone have any hard numbers to support going with Downpipes? Want to leave the exhaust sound alone for the most part.

I don’t think the down pipes added any actual power but I did notice the turbos spoiled up a little faster.

I saw on a post from spd that they were claiming 26hp and like 40ish lbs but I asked them on a few Instagram post and they did not respond. If they do make that I don’t know why they wouldn’t advertise it..... I have adaptors and down pipes and can’t really tell but it spools up quicker.

Not a chance.... don’t bother.
