H Pipes

H-Pipes & Exhaust H-Pipe Crossovers

H-pipes connect the two banks of a dual exhaust system with a crossover tube, balancing exhaust pressure between cylinders and producing a deeper, more traditional V8 exhaust note compared to X-pipe designs. H-pipes are a popular choice for muscle car and truck builders who want that classic American V8 rumble.

OneFastShop carries H-pipes including direct-fit and universal H-pipe crossovers, stainless steel and aluminized steel construction, catted and non-catted configurations, and H-pipes in popular pipe diameters for muscle cars, trucks, and dual-exhaust V8 platforms.

Every H-pipe at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're adding a classic crossover tone to a V8, replacing a rusted mid-pipe, or connecting dual headers to a cat-back system, OneFastShop has the H-pipe. Shop the full H-pipes collection today.
