Best Header for the 2022–2026 WRX: 5 Top Picks for Rumble or Power

The best header for a 2022–2026 WRX depends on what you're chasing: the JDMuscle unequal-length header ($599–$699) brings back the classic boxer rumble for the least money on this list, while the GrimmSpeed equal-length header ($1,029) is the pick for drivers who want the smoothest, most efficient flow to the FA24's twin-scroll turbo. Between those poles sit Invidia's UEL and EL manifolds and a budget EL option from PLM. Here are the five headers we'd actually buy, compared.

The header is the single biggest sound decision you make on a VB WRX. The factory FA24 manifold is an equal-length design, which is efficient but gives up the uneven exhaust-pulse timing that made the boxer rumble famous. Swapping to an unequal-length header restores that sound; sticking with (or upgrading to) an aftermarket equal-length header keeps pulses even and maximizes flow. There's no wrong answer — only a tradeoff between soundtrack and scavenging.

1. JDMuscle [22-26 WRX] Unequal Length Header — $599–$699

The JDMuscle [22-26 WRX] Unequal Length Header - MT&CVT is our pick for most drivers, and the cheapest way to get the rumble back. It's built from SS304 stainless steel, fits both manual and CVT cars, and exists for one reason: if you've been craving that iconic off-beat boxer sound since the VB went twin-scroll, this is the fix. Being our own brand, it's also priced hundreds below the name-brand UEL options here. Best overall value on the list.

2. Invidia [22-26 WRX] FA24 UEL Manifold Exhaust — $959

Invidia [22-26 WRX] FA24 UEL Manifold Exhaust is the premium take on the same idea: unequal-length runners for the rumble, with Invidia's larger-diameter, smoother-bent piping aimed at reducing backpressure and helping the turbo spool. Choose this if you want the UEL sound backed by one of the biggest exhaust names in the Subaru world.

3. GrimmSpeed [22-26 WRX] Equal Length Header — $1,029

The GrimmSpeed [22-26 WRX] Equal Length Header is the performance-first pick. GrimmSpeed designed it by analyzing the factory manifold's shortcomings and optimizing runner geometry around it — equal-length pulses feeding the twin-scroll turbo as evenly as possible. It won't rumble like the UEL options, but if your WRX is built for speed rather than soundtrack, this is the engineering-led choice.

4. Invidia [22-26 WRX] FA24 Equal Length Manifold (HS22SW4HDEL) — $897

Invidia [22-26 WRX] FA24 Equal Length Manifold | HS22SW4HDEL splits the difference between the GrimmSpeed and the budget pick: Invidia's equal-length design and build quality at a mid-range price. A strong option if you want the EL efficiency story without paying the top of the market.

5. PLM [22-26 WRX] Equal Length Header — $650

The PLM [22-26 WRX] Equal Length Header is the budget EL play — an equal-length manifold for the FA24 at hundreds less than the big-brand equivalents. If your priority is freeing up flow on a budget and you don't care about the badge on the box, this is where your money goes furthest.

Quick comparison

How to choose

Sound first, or speed first? Unequal-length headers bring back the boxer burble that defines the Subaru soundtrack — at the cost of less even pulse timing. Equal-length headers keep the exhaust pulses evenly spaced, which pairs naturally with the FA24's twin-scroll turbo. Decide which you value more before you look at prices.

Budget reality. A header swap is a bigger job than a cat-back — heat shields, tight engine-bay access, and gaskets all come into play. Budget for professional installation, and plan on a tune to get the most out of the new flow characteristics.

Transmission fitment. Not every header fits both gearboxes — the JDMuscle UEL is listed for MT and CVT, but always confirm fitment for your specific car before ordering.

Bottom line: start with the JDMuscle unequal-length header for the rumble at the best price — or go GrimmSpeed equal-length if your build sheet cares more about flow than soundtrack.
