These Kooks packages cover the 2014-2019 Corvette LT1, LT4 and LT5 range, combining stainless long tube headers with a catted X-pipe and the OEM rear connection. Straight and stepped primary options let you choose the package for the engine you have or the build you are planning.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSKUs:\u003c\/strong\u003e 2170H430, 2170H440, 2170H530, 2170H630, 2170H640, 2170H6SS\u003c\/p\u003e\u003ch2\u003eChoose the header and catalyst together\u003c\/h2\u003e\u003cp\u003eThe stepped primary starts at 1-7\/8\" and increases to 2\"; the straight designs use either 1-7\/8\" or 2\" throughout the primary. All use 3\" collectors. GREEN and H.O. GREEN catalysts suit naturally aspirated and forced-induction applications within their ratings. H.O. GREEN uses a larger 4-1\/2\" body and 300 CPSI substrate, compared with the 4\" body and 400 CPSI substrate of GREEN.\u003c\/p\u003e\u003ch2\u003eKeep your compatible OEM rear exhaust\u003c\/h2\u003e\u003cp\u003eThe 3\" X-pipe finishes with a 2-3\/4\" OEM rear connection.

GREEN catted X-pipe arrangement and separate competition-only front pipes. It gives you both pipe sets, rather than supplying a catalyst-free system alone. The competition pipes are not for public-road use, and a competition-use waiver is required for the package.\u003c\/p\u003e\u003ch2\u003eFitting and ownership\u003c\/h2\u003e\u003cp\u003eGaskets, header bolts, O2 extensions and clamps accompany the header installation. We recommend professional fitting and a tune for the long tube conversion. The mid-pipe clamp studs may need trimming to clear the belly pan; that clearance check helps avoid a rattle after installation. Check the fasteners again after the first heat cycle.\u003c\/p\u003e\u003ch2\u003eTuning for your header upgrade\u003c\/h2\u003e\u003cp\u003eWe recommend a tune with these headers, matched to your engine and the completed exhaust.
