Stage 2 exhaust system for all injection cars and late carb models using catalytic converters. This RC40 style single box muffler bolts on directly after the cat for easy fitment. The stage 2 is a bit louder than the stage 1 but flows even better. Don't forget to get new hanger mounts (WC-DBP7104) and gasket (WC-GEX7761) and if you want to do a cat delete at the same time check out our cat delete pipe (WC-C-ARA664).
