I can't decide which exhaust to go with (RSR GT2, Blitz, Injen, Stillen). I would like to see some Dyno results so I know which to go with but I haven't been able to find any. If any of you has one of these exhaust systems please let me know how you like it, thanks

even though it wasn't in your list, fujitsubo would be my pick..

but out of your list, i would say stillen would be best for gains, but if you can't afford it, then go for injen..
