Third party dyno testing on a Dyno Dynamics dynamometer revealed gains of 40 whp when paired with a tune, with 20 whp gains unlocked by Competition Headers alone after the tune had been applied.\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCONSTRUCTION:  \u003c\/b\u003eEach header is assembled out of T304L stainless steel and rigorously quality checked in-house.
