[QUOTE="yewly1990, post: 1064415278, member: 157782"] I not sure how the back pressure assist our car to move easier, all the exhaust shop tell me same as u, s-flow is best for auto car, since it have the best back pressure. Speedwork was the only one who tell me, 4-2-1 and straight flow are recommended for all the car to get the maximum power =\, I know 4-2-1 are very useful to city driver since we are always doing stop and go, and automatic transmission can`t raise our rpm to 8k. But I having question with the back pressure method. As the information I get from some oversea website and some magazine, they said exhaust system should had the least restriction to the exhaust flow to get the best power gain. The more restriction means more back pressure generated, making the engine work harder to pump out the exhaust gases from cylinder. And it count as one source of pumping lost. I get stuck between 2 theory, which one said exhaust are design to let go exhaust gases as fast as possible for all the car, and another theory which said back pressure are use to be gain more power to automatic transmission???
