GrimmSpeed Catback Exhaust Kit

With so many catback options available, our goal was to create a unique, refined sound in an extremely high quality system. We've been casually referring to it as the gentleman's catback around the shop, to ensure that our mission was not lost in all of the craziness. We also wanted to produce a single system that would fit as many models as possible. Using a unique hanger design and by including a set of four custom polyurethane hangers with each kit, we've been able to fit all EJ and FA20DIT WRX and STI sedans from 2011 to 2021.
