Probably a dumb question re: bolt-ons

When you get tired of that go FI if you want, But headers and HFC's are waste of $$$ to me. I made 298 WHP and 240 WHTQ on a mustang dyno, Auto 7 spd X Coupe, With Gen 3's, cat back and tune, stock cats and manifolds,

My sig numbers are of course FI, cat back ,Stock cats and manifolds.

I think I'm gonna just do berk HFCs and the FI catback + uprev tune and be done with it (for now anyway)

Looking like FI catback exhaust + berk HFCs will be the way I go unless someone sees a huge problem with that setup.
