Rule of Exaust Set Up? Options

[o0black0o]

Is there a rule for the exaust set up? When I say that I mean Power = Size of Piping?

Also anyone give me a idea 2 what piping and effect each celica engine would have.

ex. 7afe, 5sfe, 3sgte, etc.

Yea, that's almost what I'm gonna do with my 3s, although, I'll only use 2.25 inch pipe as I need that added back pressure for cruising over the mountain range twice a week. (again, as per TRD recommendations for my particular circumstance)

LOL... backpressure. Backpressure = BAD BAD BAD no matter what. Exhaust travels in pulses and faster pulses = more power. Backpressure is when those pulses get crammed together, which equals bad performance (clogged cat anyone?). Torque loss with exhausts is because when engine load is reduced from free flowing exhausts, the exhaust velocity also slows down (at lower rpms). However at higher rpms, the exhaust velocity can speed up FASTER and create more power... but too big of piping on a small engine HURTS performance because the engine cannot spit enough exhaust to fill the extra space and speed up the flow. Make sense?
