H-Pipes

H-Pipes: the mid-pipe section that ties your exhaust together and changes how it sounds

An h-pipe is the crossover section that sits between your headers or manifolds and the rest of the exhaust. On a V8, the equalizer tube linking the two banks balances pulses side to side, which is where the classic muscle-car rumble comes from. Swapping a restrictive factory mid-pipe for a freer-flowing h-pipe (or an x-pipe / xo-pipe variant) is one of the most common early exhaust jobs, and h-pipes bolt in ahead of your cat-back section. Some versions keep converters in the pipe, others delete resonators, and the choice you make here sets the tone for the whole system.

What ThreePiece stocks

There are 12 h-pipes in stock right now, spanning 9 brands: BBK, CORSA Performance, Borla, Ford Racing, Mishimoto, Roush, Stainless Works, AWE Tuning and Kooks Headers. Prices currently run from $279 to $850 — that is the live range for what is on the shelf, not a fixed offer. Fitment data covers 11 of the 12 products, weighted toward Ford and Chevrolet, with the Ford Mustang, Chevrolet Corvette and Ford Raptor as the top vehicles across model years from 1986 to 2025.

Concrete examples: the CORSA 3in Double X Pipe for the 2015-2024 Mustang GT 5.0 sits at the top of the range, the AWE Tuning Performance H-Pipe for the 2017+ Raptor covers the truck side, and the CORSA C6 Corvette 6.2L XO Pipe handles the Chevy V8.

How to choose

The first decision is converters. The BBK High Flow H-Pipe for the 86-93 Mustang 5.0 and the BBK short mid h-pipe for the 96-04 4.6 GT/Cobra keep catalytic converters in the pipe; the second is cut for use with long-tube headers, so match it to your header setup. A resonator-delete piece like the Stainless Works Mid Resonator Delete H-Pipe for the 18-21 GT trades quiet for volume.

The second decision is h-pipe versus x-pipe. An h-pipe leans toward a deeper, traditional tone; an x-style or xo crossover tends to be raspier and higher-pitched. Both are represented here, so pick by the sound you want. Also confirm pipe diameter matches the rest of your system — several here are 2-1/2in and 3in.

What else you need

An h-pipe is one link in the chain. Pair it with Headers up front and a Cat-Back Exhaust or full Cat-Back System behind it, and finish with Mufflers. If you are keeping converters, browse Catalytic Converters, and check Exhaust Flanges for the connections. Everything lives under the main Exhaust section.
