I recently put a short ram injen airtake and was wondering what i should put next thinking of getting stillen headers n stillen cat back any other mods performance wise

If you're just sticking with ready-made bolt-on parts. Go with the Stillen headers, and Borla axle-back. The upgrade your car's suspension with, then aero enhancements.

How much hp do you get with the stillen headers thinking of going full catback n up rev tuning it then putting coilovers maybe light weight pulley
