Do you own a 20th-anniversary GTI? 😍 Have you wanted to change how it sounds to be more aggressive? You may want to check out our MK4 cat-back system. Designed by our in-house engineers, the straight-through 2.5-inch flow path is all about reducing restrictions and turbulence, which translates to smoother airflow and better performance. Plus, the stainless steel resonator takes care of any unwanted drone, giving you a sporty sound that’s fun without being overwhelming. Oh yeah, It’s also lighter than the stock setup—21 pounds compared to 27 pounds for the OEM exhaust. Look up ES4338303 to find this cool guy! #ecs #ecstuning #thisisecs #mk4 #gti #vwmk4 #20thmk4 #vw #jetta #wookie #gti #mk4gti
