Why P1?

These headers aren't just good-looking — they're track-tested by the team at Rooster's Factory Support. If we bolt it on our car, we sell it in our store. The 2026 redesign improves fitment and flow over previous versions, making this one of the best bolt-on performance upgrades for your 305 program.
