Beyond Redline Stage 2:
Reflash, CAI, Downpipe, Catback, 550cc injectors, Intercooler, Reflash: +65whp/70wtrq

If I decide to get a Genesis Coupe, I would like to go BR Stage 2 as soon as I get it. That would put me at around 250whp so I wouldn't miss my 2010 WRX too much which is at about 260whp (catback + tune) depending on what dyno you're on.
I was a little surprised when I saw that BR only claims a 20whp/5wtrq increase from Stage 1 to Stage 2 with deleting the 2ndary cat, larger injectors and a FMIC. But I guess once you're Stage 2, you're all prepped up for a turbo upgrade.
