I have a pair of 1 3/4" 2005-2007 LS2 C6 Corvette Melrose Smoothflow Ceramic Coated Headers with O2 Sensor Extension. These are ceramic coated headers and fitment is great. The coating is still in good shape. These headers are probably one of the finest, if not the best headers for a C6 Corvette. They are made from aluminized steel, rather than stainless steel. And are coated inside and out to perfection. Brand new they were around $1k. You can either fit/mount these on to your factory mid pipe or 3 inch highflow cats or 3 inch straight pipe.

$550 free shipping, lower 48 states.

"Melrose Headers high performance header kit will take your C6 performance to a whole new level. Constructed by hand utilizing CNC cut exact-fit flanges, 1-3/4" tubes and 3" collectors. Named " Smooth Flow" as result of their construction having no sharp bends and very few welds. These headers are manufactured by the same folks that worked with GM to produce and supply the headers for the LS-2 engines in ASA racing series. Threaded oxygen sensor bungs come installed. Dyno proven gains of up to 38 RWHP and 35 RWTQ."
