[QUOTE="SlowSVT, post: 8899776, member: 20202"] Now I see where your philosophy is coming from. 2 completely different exhaust configurations. A Turbo will spool most efficiently when there is maximum pressure differential between the turbo inlet and the outlet. The ideal exhaust on a turbo is not having piping or any kind on the outlet of the exhaust scroll. That’s why you see 4” pipes after the exhaust scroll. A turbocharged engine has a substantial amount of backpressure from having multiple cylinders dumping into one or two turbos. A supercharged or NA engine will have more efficient exhaust because they can take advantages of the pressure waves created by each exhaust pulse (when you have a high pressure wave there is always a low pressure wave right behind it and you want to take advantage of that at the next exhaust cycle to help scavenge the cylinder). Turbo’s just pressurize the exhaust manifold to drive the impeller and diffuse the pulse pressure. While I am certainly no expert on exhaust system design I do have first and experience what the effect are if you install to large a system or minimize backpressure. THEY RUN LIKE CRAP! The engine stumbles at low speed and you can never seem to get the engine to run right. Backpressure and optimal exhaust velocity is what you are after something an overly large pipe won’t do.
