GrimmSpeed Pulley Cover - 2022+ Subaru WRX, 2019+ Subaru Ascent Engine

GrimmSpeed Pulley Cover - 2022+ Subaru WRX, 2019+ Subaru Ascent EngineFITS: 2022+ Subaru WRX GrimmSpeeds Engine Bay Shrouds have been a favorite amongst Subaru Enthusiasts for nearly a decade due to their minimal design and painless installation. They are a go to as a first modification as they do not require tinkering with any complex engine functions or tuning after installation. They are a simple way to upgrade the aesthetics of your vehicles engine bay. Our Pulley Cover is designed to complement the GrimmSpeed

The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a 180-degree out-of-phase sound wave that cancels out problematic frequencies

our HPFP kit raises the ceiling on what was previously thought possible

which gives them about 1000% (that’s ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice)

Mounts in the stock location so there is no need for cutting or trimming of any sort

this downpipe offers a more aggressive exhaust note

The harmony of the signature ARK Performance mufflers with Helmholtz technology provides all the best sounds while leaving out the drone

they eliminate plastic parts that tend to flex on the OEM cables

and comes with everything needed for a plug-and-play install

The main goal of this mid pipe was to tame the beastly rasp caused by the increased flow of RV6™ PCDs™ and Jpipe

FTW and other MTBE oxygenated race fuels
