Tomei has released an extremely affordable and lightweight exhaust for the GRF/GVF WRX STI. Tomei has designed this exhaust system with performance and weight reduction in mind, using titanium over steel and designing the exhaust with minimal bends as possible. The catback exhaust weighs in at just 15.8 lbs compared to the stock exhaust that weighs 50lbs! To even further the weight savings, instead of using the traditional gasket and flange design, they designed the exhaust with slide joints and a hose clamp setup.
