Ace Race Parts carries a variety of exhaust pipe adapters, connectors, couplers, and other fittings. Our 304 Stainless Steel and 6061 Aluminum Tube Fittings are a high-quality, cost-effective solution for header, exhaust, intake, and downpipe builders.
Our 304 Stainless Steel Exhaust Fittings are manufactured to the stringent ASTM A270 Sanitary specification, which offers a much higher quality finish and welding experience than other specifications of exhaust pipe adapters due to an extensive testing and inspection process prior to shipment. 304 Stainless Steel Exhaust Pipe Fittings are available as Transition Reducers from 1.500" to 5.000" diameters.
Our Aluminum Transition Reducers are available in 6061 Aluminum with a highly polished finish and work perfectly in conjunction with our Aluminum Mandrel Bends, Aluminum Tubing, Aluminum V-Band Clamps and Flanges, 4-Ply Silicone Hoses, and Stainless Steel T-Bolt Clamps.
