Kooks buillds all of their products to the highest standard, and these are possibly the best headers you can buy for your 1997-2004 Corvette. These 1997-2004 Stainless Long Tube Race Version (Non Emission) Headers (No AIR/EGR) feature 1-7/8" primaries and 3" collectors with O2 Bugs welded into the merge collectors.
These 304 stainless steel long tube headers are for the 1997-2004 LS1/LS6 Powered Chevrolet Corvette.
To connect these headers to your exhaust you will need a Kooks high flow X-pipe. These all 304 stainless high quality X-pipes come without cats (off road), or with Kooks high flow catalytic converters. On top of the standard rear O2 bungs, these X-pipes also include an extra O2 bung and screw cap for wideband tuning. The standard X-pipe size is 3" inlet, 3" Center Section, and 2.5" Outlets to connect to your stock/aftermarket 2.5" axleback.
Fits 1997-2004 LS1 2001-2004 LS6
