This Kooks range covers the 2014-2019 Corvette with LT1, LT4 or LT5 power, offering straight and stepped primary designs with 3\" collectors. Choose the version that suits your engine, then pair it with the matching Kooks X-pipe for a system that fits together properly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSKUs:\u003c\/strong\u003e 21702400, 21702500, 21702600\u003c\/p\u003e\u003ch2\u003eStraight or stepped primaries\u003c\/h2\u003e\u003cp\u003eThe 1-7\/8\" and 2\" versions use a single primary diameter.

That distinction matters when comparing the options: the stepped header is its own design, rather than another name for the straight 2\" version.\u003c\/p\u003e\u003ch2\u003eUseful fitting parts included\u003c\/h2\u003e\u003cp\u003eCometic multi-layer gaskets, stainless header bolts, O2 extensions and Torca clamps are included.
