Hours of dyno and race track testing have resulted in this new light weight fully stainless exhaust system for the 4AG AE86 Corolla.
 
This exhaust system is hand built by skilled technicians utilizing high quality, lightweight stainless steel.  Exhaust runs below the rear differential assembly for optimum flow and straightest path (instead of looping up and above and routing over the differential assembly which causes flow restrictions and limits power output).
-Exhaust track runs below diff assembly.
-Ø60mm standard catalyst can be used.
-The internal design based around a constant Ø60mm pipe.
