Performance mods.
 

Hello, just bought a 2015 Scion FR-S. Before this owned a 2002 SVT Lightning. Final out come 459 RWH - 547 TQ. Totally stock except for mods to blower, exhaust, tuning. Basically air in air out no internals stock block.:burnrubber: Needed a brake from 10mpg. What is the best bang for the buck just short of forced induction. Exhaust, intake, tuning. What kind of dyno numbers can I expect? Has any body done a windage tray? High flow cats or no cats? Little help please!!!

Congrats and welcome. You might want to look in the technical topics section. Tons of information there. Your questions have been ask many times.

Enjoy your car!

e85 #1

e85 + header back exhaust #2

Header back #3

All with tune of course

Tune first thing. E85 of course if it's in your area. Worry about exhaust next, starting at the header, then over pipe, front pipe, catback, in that order. Intakes don't do a whole lot for this car, the stock setup is pretty good. Drop in a high flow filter, and maybe a silicone tube instead of the rubber accordion one.
