996 GT3 Exhaust Most Porsche's 996 GT3 (1999-2005) leave plenty of room for improvement when it comes to horsepower and torque. Most stock exhaust systems are chosen because they are the least expensive alternative when it comes to the high performance exhaust systems. An aftermarket performance system will free some power in your engine. This means your engine will breathe better and fuel and air exit the combustion chambers faster. This means more fuel and air can be burned to create more power. Shop for your exhaust system here at Trinity Autosport.
