TPIS C4 Headers, Painted 84-91 Corvette w/emissions ** Available Aprox. 12/2/22 If Ordered Today **
In the late 80's we looked at all the headers on the market and found that nobody made a header with the right size primary tubes. The stock header is woefully inadequate, so we set out to make a header that truly performs. These headers fit beautifully and utilize all the factory bolts and brackets and are installed from the bottom with no cutting or welding required. These headers make an average of 20hp and 20lbs/ft on a mild engine and also make changing spark plugs a snap. All of our Corvette headers feature 1-3/4" primary tubes and 3" collectors. Y-Pipe sold separately. Fits 84-91 Corvette and retains all emissions hook-ups.
NOT EMISSIONS LEGAL IN ANY OF THE STATE OF THE U.S.A.
