The BNR Catless Downpipe for your 2012+ Sonic and 2011-2016 Cruze 1.4T First Gen is one of the best exhaust mods you can do for power and sound. Faster turbo spool, more turbo whistle in your exhaust, and more power! Manufactured from 304 stainless steel. Competitors use cheaper, lower grade, made in china steel- which rusts and breaks at the welds. BNR downpipes will not have these problems!
