From SCP website...
"We have shown a few shots of the stock exhaust to show you have bad it is. Note the 90 degree bend on the drivers side downtube. Note the pinched piping coming out the rear of the stock resonator. The stock piping is dual 2" to a single 2.5" to dual 2". Your car is begging you....UPGRADE the exhaust and our 2.5" to 3" to 2.5" system is the perfect solution!"
