Performance Y-Pipes and Mid-Pipes are the missing piece from most exhaust systems.
While cat-back exhaust systems add performance and an aggressive growl they don't replace the entire exhaust system and leave performance on the table. The Y-Pipe or Mid-Pipe links your performance header with the rest of the exhaust system and typically use larger diameter, mandrel bent piping for more power and torque. Equipped with either a high flow cat or no cat at all, no system is complete without a performance y-pipe or mid-pipe.
Y-pipes get their name from their shape, typically connecting the left and right bank of a V8 or V6 engine into a high flow collector that attaches to the rest of the exhaust system. True Dual exhaust system don't have a Y-pipe but can come in other configurations, like X-pipes, Mid-Pipes, Connection Pipes, or Crossover Pipes. No matter the name the purpose is the same - more flow for more power.
