For C4 Corvette owners, American Racing Headers has finally answered the call. Your long awaited C4 systems are here! With features you'd expect from ARH including all 100% US made 304 S/S construction, 3/8" thick flanges with hand ported inlets, merge collectors with scavenger spikes, your choice of 1-3/4" or stepped 1-3/4" X 1-7/8" primaries and our 3" or 2-1/2" X-Pipe equipped exhaust (with or without our 200 cell metallic substrate cats), it simply doesn't get better. The system is designed to splice into your factory or aftermarket exhaust on 92-96 models; but will also fit 84-91 Vettes with mild adapting. Will also work with straight or angle plug heads. Expect minimum gains of 25 RWHP.
Convertibles require our 2-1/2" X-Pipe mid-section and are not available with cats.
