1. GrimmSpeed Unequal Length Header
If you’re looking to get that classic Subaru rumble without sacrificing performance, the GrimmSpeed Unequal Length Header is definitely worth a look. They really put in the work to make this header something special. Unlike a lot of other aftermarket options, GrimmSpeed designed theirs with equal length runners within each bank, but one bank is 1.5 times longer than the other. This gives you that unmistakable Subaru sound while still aiming for the performance benefits of an equal length setup.
They used some pretty advanced tech, like 3D scanning and printing, to figure out the best runner lengths and angles. Plus, they made sure it fits with different oil pan setups, which is a nice touch. The collector is a cast 304 stainless steel piece with a low-angle merge, which is supposed to help with faster spool and better throttle response when you’re not on the boost.
GrimmSpeed claims their header offers substantial power and torque gains over the stock unit, often around +25hp and +25 ft/lbs of torque. They also state it’s the quickest-spooling aftermarket header available, outperforming competitors and even some equal-length designs in certain metrics.
When it comes to actual gains, GrimmSpeed’s own testing shows some pretty impressive numbers. Compared to the stock header, they saw maximum gains of around 25 wheel horsepower and 25 ft/lbs of torque. What’s interesting is that even though it might lose a little bit of low-end spool compared to the factory header, it makes more power everywhere else due to better efficiency. They also tested it against other aftermarket headers, both unequal and equal length, and found their UEL header could out-spool the competition and provide significant power increases.
One of the best parts? GrimmSpeed says it’s a simple bolt-on and doesn’t require a tune, making it a pretty straightforward upgrade. The flanges are a beefy half-inch thick, and the runner pipes are 14-gauge, so it seems built to last.
