1-3/4" Long Tube Headers w/ 3" X-Pipe

The American Racing Headers C4 Corvette long tube header system is engineered to meet the demands of C4 Corvette owners seeking enhanced performance. Manufactured entirely in the USA from 100% US-made 304 stainless steel, this system boasts 3/8" thick laser-cut flanges for a warp-free seal and hand-ported TIG welded inlets for optimal flow. The merge collectors feature scavenger spikes, and the primary tubes are available in either 1-3/4" or a stepped 1-3/4" X 1-7/8" configuration. The system includes a 3" X-Pipe, with options for 200-cell metallic substrate catalytic converters known for their extreme durability. Installation of this system requires an OEM GM LT1 Oil filter adapter; without it, the headers will not fit. Buyers must specify the exact model year, whether the vehicle has EGR, if it's a coupe or convertible, and the transmission type (manual or automatic) at checkout to ensure proper fitment. It is critical to note that all American Racing Headers products are manufactured exclusively for racing purposes. Installing these products on a vehicle eliminates its legal use on public roads and highways and may be subject to fines and/or criminal liability under the Clean Air Act. This system is intended strictly for closed-course competition use and is not legal for street vehicles or other non-racing competition off-road vehicles. A Vehicle Compliance Waiver must be signed prior to purchase.
