T1R offers a true 3" (76.3mm) dual resonated Exhaust system for the FK8. You will maintain your stock catalytic converter for emissions.
T1R exhaust is constructed with full stainless steel with a distinctive TRI-tip. Besides that, it maximizes the exhaust flow out of the engine. From our dyno testing, the exhaust gained about 30whp / 31WTQ (91OCT fuel) alone without any additional modifications.
Since the exhaust is dual resonated, exhaust noise at 3500rpm is under 82 db.
