H & X Pipe Exhaust Kits and Pipes

What Does an X Pipe Exhaust Do?

An X-pipe connects both banks of a dual exhaust at a crossover point so exhaust pulses from each side can balance. According to JEGS tech content, X-pipes grew out of the H-pipe design and often deliver better scavenging. Balance pipes also make a dual exhaust quieter than the same system without one.

You can buy an X-pipe three ways: built for a specific application, as a universal kit you fit yourself, or built into a cat-back system. For a wider look at how crossovers fit into a full setup, read our overview of types of exhaust systems.

The crossover works with everything upstream, so plan it alongside your manifolds or headers. Our buyer's guide to exhaust headers covers header styles. When you're matching components, shop the full lineup of headers and exhaust parts.

X Pipe vs H Pipe: Which Crossover Fits Your Build?

Pick an H-pipe when low-rpm torque is your priority, and pick an X-pipe when you want the better scavenging a merged crossover often delivers. An H-pipe joins the two sides with a straight balance tube. The 2.5 in. universal H-pipe kit in this category uses two T-sections, and its product page notes it can enhance low-rpm torque.

An X-pipe merges both sides in an X-shaped center section where the pulses cross paths. Mustang owners can choose either style here. This category carries a direct-fit H-pipe for 2015-2018 Mustangs and direct-fit X-pipes for 1996-2008 and 2018 Mustangs.

Both styles need a true dual exhaust. If your plan routes two pipes into one, browse exhaust Y-pipes instead. Check the Part Type filter to see H-pipes and X-pipes side by side. If you're swapping one style for the other, compare the model years in each listing before you order.

Universal vs Direct-Fit X Pipe Exhaust Kits

Universal kits let you set the crossover location yourself, while direct-fit kits are built for a specific vehicle. Here's how the two compare:

• Universal kits are sold by diameter and fitted to your own routing, which suits custom builds.
• Direct-fit kits target specific vehicles, such as the 2005-2008 Mustang V8, 2010-2014 Camaro, or 1994-1996 Impala SS.
• Some direct-fit mid-pipes include catalytic converters.
• After-cat X-pipes install behind the factory converters.

Direct-fit kits save fitment time on supported vehicles. Universal kits make sense when your build uses a swapped engine, custom headers, or routing that no direct-fit kit covers.

JEGS universal X-pipe kits come in aluminized steel, including a 3 in. kit, and 409 stainless, and you can bolt them on or weld them in. Need extra length or a tighter turn? Add exhaust tubing bends, or browse the full exhaust piping category.

Choosing Pipe Diameter and Material

Match the X-pipe diameter to your current tubing, then choose a material that fits your budget and finish preference. Use these points with the Outside Diameter and Material filters:

• 2.5 in. X-pipes cover many direct-fit Mustang and Impala SS kits, plus universal options.
• 3 in. X-pipes include universal kits in aluminized steel and 409 stainless.
• Aluminized steel appears in 16-gauge universal kits, including X-pipe and H-pipe versions.
• 409 stainless is used in mandrel-bent X-pipes with reinforcement plates at the welds.
• 304 stainless shows up in 2.5 in. X-pipes with 45-degree designs.

Before you add to cart, check the Inlet/Outlet size filter so the crossover matches the pipes on each side. The Overall Length filter helps you confirm the kit fits the space under your vehicle. If you want gaskets or clamps in the box, use the Gaskets Included and Hardware Included filters.
