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\u003cimg loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2487 size-large\" src=\"https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno-1024x465.jpg\" alt=\"\" width=\"1024\" height=\"465\" srcset=\"https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno-1024x465.jpg 1024w, https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno-510x231.jpg 510w, https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno-64x29.jpg 64w, https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno-300x136.jpg 300w, https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno-768x349.jpg 768w, https:\/\/soulpp.com\/wp-content\/uploads\/2017\/09\/GT4_Dyno.jpg 1280w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCONSTRUCTION: \u003cspan\u003e \u003c\/span\u003e\u003c\/b\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\u003cp\u003e\u003cb\u003eBOLT ON AND GO: \u003cspan\u003e \u003c\/span\u003e\u003c\/b\u003e\u003cspan\u003eEach product is tested in a fixture to ensure perfect fitment.
