Small turbo and exhaust bore
Discussion
Was encouraged to change the exhaust downpipe and cat on a small engine turbo car for something with a larger diameter to reduce any restrictions. It feels as if the car has lost some low end torque. I was speculating that perhaps with a larger bore pipe the exhaust gas speed will be less resulting in a reduced turbo speed at lower RPM. Is that a valid thought or nonsense ?
