@synergymfg: Our SEMA 392 gets a monstrous exhaust upgrade thanks to the team over at @magnaflow who sent us their Rock Crawler Series Cat-Back Performance Exhaust System. The Mars JL was ready to rip out of the shop right after the quick install and aching to hit the trails soon! Where should we take this thing? 🔥 Ready for an upgrade? Available now! @Poly Performance 🔥 #synergymfg #magnaflow #steering #suspension #upgrade
