Header!!
And you can get a good header without spending a ton, People seem to love the Gruppe UEL and it’s about 400-500. The Borla UEL is about 600-700 too. There’s no requirement to spend the 1000+ some of us do on JDL and ACE (myself included).
Gruppe has an ongoing Group Buy for their UEL. If interested check out their thread:
