We chose appropriately sized catalysts to flow enough power for sustained high RPM use – where the GT4 is at home. Don’t settle for smaller, cheaper catalysts when power and durability is concerned. Third party dyno testing on a Dyno Dynamics dynamometer revealed gains of 30 whp when paired with a tune, with 12 whp gains unlocked by Street Headers alone after the tune had been applied.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003eHAND-CRAFTED CONSTRUCTION\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eEach header is assembled out of T304L stainless steel and rigorously quality checked in-house.\u003c\/span\u003e\u003cspan\u003e Proven design elements including port matched flanges, smooth radius primary tubing, and collectors that optimize the exhaust flow all work in conjunction to maximize power gains.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003eBOLT ON AND GO\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eEach product is tested in a fixture to ensure perfect fitment.
