Message: <blockquote data-quote="donCityZ" data-source="post: 1956443" data-attributes="member: 22885">kweng, are u sure? i was told otherwise by other people and by reading in the net. straight flow = cause to lose many backpressure (very low resistance for exhaust gas to exit)... if your car of lower cc (2000cc or below), and NA, it is advisable to use stock exhaust diameter. since low cc, there are not much gases to let out anyway if compare to turbo cars or higher cc cars. back pressure is very critical to have a good low end torque. at any time, the point is not to eliminate back pressure totally, its just to reduce a bit to optimal level. my opinion is that, using stock diameter with s-flow or semi flow probably the best setup for all 2000cc and below cars. if u just dunk in turbokits or the turbo halfcut, then the need to change exhaust diameter and bigger straight flow mufflers (or small muffler, but twin) comes in.this exhaust concept can be applied almost similarly to induction too. (intake).induction also need some sort of frontpressure to maintain low end torque. You can test by taking out the piping before the air filter box. sound more garang.. but low end torque diminishes. but try floor the pedal till 4-5k rpm.. u will feel the force greater than before.</blockquote>
