EXHAUST PERFORMANCE ??? Oo naman , if proper exhaust of the car is installed , a big amount of power can be attain . pero ibat ibang gains depends on the condition of the car at ang right piping combo . The exhaust and collector plays a big part sa performance ng auto , without the other ay minimal ang mga gains at mandrel bent pipes plays a big part too .


A Honda Civic with B16A can easily make 18 horses with a 2.5 inch piping and a 4 to 1 collector / header . :D
