For those who like it raw, rowdy, and light, the AWE Track Edition is for you. The Track Edition shares the same bespoke design and precision engineering as its Touring Edition counterpart, minus AWE’s patented drone-canceling solution, 180 Technology ®, providing a weight savings of 39 Pound over stock. In place of the 180 Technology ® resonators are Track Edition straight pipe sections. As a result, this version is known to get rowdy during mid-range acceleration and deceleration, as well as becoming more noticeable within the cabin during V4 mode. Due to this reason, AWE Track Edition Exhausts cannot be returned based on sound preference. How do we avoid the Check Engine Light? AWE has engineered an electronic solution to simulate both AFM and NPP valves, resulting in the ECU remaining happy, allowing the C8 Corvette to operate at full stride with no CELs and maximum peace of mind. Each included kit includes two pairs -- one for AFM, and the other for NPP. If your C8 does not have NPP, only one pair will be used. Purely plug-in and rip! And if one day you decide that the Track Edition is too loud for you, we made it easy to convert between Track and Touring Edition configurations with our convenient Conversion Kits. Easy! There's a reason AWE is the leader in C8 exhausts, and you're looking at it.
