GrimmSpeed Non-Resonated Catback Exhaust System Subaru WRX STI Sedan 2011+

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.

Features:

Custom dual outlet mufflers - dual perforated tubes offer quieter, more refined tone
Quad 3.5'' double-wall, angle-cut tips - our most commonly requested configuration
Resonated or Un-resonated options - the choice is yours, although we recommend resonated for the FA20DIT and un-resonated for the EJ
304 Stainless Steel construction - genuine American 304SS material to withstand the elements and abuse
1/2in thick flanges - all 7 flanges are laser cut from the same 1/2in thick stainless plate for perfect sealing, easy installation and extreme durability
Flex section - your motor and mufflers are both mounted using rubber or poly mounts and can move independent of one another - if there isn't a flex section or donut gasket allowing relative movement, there's a much greater likelihood of damage to your exhaust or turbo
Custom polyurethane hangers - these hangers keep your exhaust where it needs to be, freeing you from rattles, melted bumpers and so on
TIG welded - each catback is hand TIG welded just across the hall from the engineering offices that they were designed in, ensuring craftsmanship that does our Lifetime Warranty justice
GrimmSpeed Lifetime Warranty - buy knowing that we stand behind our products and customers 100%
