Designed To Perform!
In response to changing emissions standards, GESi has developed a new proprietary coating technology and a new S-Wound core capable of effectively meeting the latest regulations, while still supporting the performance of late model high horsepower engines when needed.

Don't get fooled by others using GESI Cats, make sure you're getting the UHO version to avoid flow limitations! Our GESI Catted J-Pipes are capable of supporting up to 850whp where others will be limited to 350-500whp.

The '22+ WRX has already shown to make nearly 500whp with just bolt ons and tuning, the last thing you'd want to do is bottleneck yourself at the J-Pipe.
