The GPP RS-Race for the 2015-on Subaru WRX/STI is our most aggressive looking system for the VA sedan chassis. The RS-Race is ideally suited applications, which require less sound suppression and maximum flow. (with the factory catalytic converter, this application has a surprisingly mild sound level for cruising and a good rumble under wide open throttle.) This light-weight, large diameter, full stainless-steel 80mm (3.14”) non-tapered, cat-back exits the (right) passanger-side and has no pre-resonator. Even with the cost-effective price point on the RS-Race, quality materials, construction and craftsmanship is not compromised. For extra customization, the RS-Race Tri-bolt tip allows for installation of optional RS Tip Silencers, various tip lengths and styles in both stainless steel and genuine Titanium.

Greddy GPP RS Race Single Catback Exhaust

Decent deep rumble tone. Drone is not that bad on roads and highways. You can still have a normal conversation inside your vehicle and on speaker phone. The right side single exhaust exit with a little angle gives that old school jdm look on the WRX/STi. The tone on WOT is not obnoxious at all. Great sound if your protuned with burble tune. I have paired it with Greddy Titanium exhaust tip to for aesthetic look. Over all I can’t say any negative things about this exhaust. I am always pleased of Greddy exhaust products over the years. Would definitely recommend this exhaust if you live in a residential area lol

Best exhaust for the wrx in my opinion it’s the perfect loudness to get some attention but not all of it & you even get some crackles in there

Great sound without an annoying amount of drone. As another user said can’t think of a complaint
