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.
