How Big Is The Stock STi Exhaust?
From a consumer’s standpoint, you should know that you get what you pay for. You see a 55 in. flat screen Energy Saver 720p/1080p HD 3D TV for a grand at Best Buy. You’d be paying for quality, efficiency, and performance. The TV unquestionably beats out your current 30 in. flat screen 30 in. 720p TV by a long shot. Same concept applies towards stock exhaust systems on a 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 and 2012 STi. A majority of STi models run on the same engines. Respectively, the stock exhaust systems are similar. While stock STi exhaust systems fully comply with energy regulations, they substantially hold back STis from reaching their fullest potential, in terms of power.
Stock STi Exhausts Restrict Power
STis are essentially, by default, turbochargers. Turbochargers utilize wasted gas to produce more power. Thus, other cars would be put to shame on the road. Exhaust flow is key. A stock STi exhaust would provide nothing more than standard performance and efficiency. If it’s not replaced, then you and your STi would be the laughing stock of the bunch. You and your ride would be inferior compared to everyone else’s ride. Because stock STi exhausts are designed to be “energy-friendly,” the pipe work limits exhaust flow. The bigger the pipes on an exhaust system, the greater the exhaust flow. And the greater the exhaust flow, the more horsepower your STi nets. The engine may also become more efficient.
Look Into An Aftermarket STi Exhaust ASAP
Performance car owners or enthusiasts would advise to replace stock STi exhausts with aftermarket exhausts because the diameter of the pipes on aftermarket STi exhausts are larger. Prevent you and your STi from being publicly embarrassed and stand out with an aftermarket STi exhaust.
