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.

but 3" is by far the best for a 3s motor

Best for loud noise. If I was getting a 3sgte and keeping it under 250whp, I would go with a 2.5" exhaust in a heart beat. At levels less than 300whp, you lose LESS than 5 whp from a full 3" exhaust. Its dyno proven.

i got this from recneps:



the exhaust piping is dependent on a lot of things.

a larger piping size and or more free flowing exhaust will push your peak torque up in RPMs, assuming youve got the cams for it. a smaller and less free flowing exhaust will push your torque band down in the RPMs.

if your peak torque is higher in the RPMs its going to result in more horsepower, this relationship is easy to see with the formula for horsepower.

hp = (peak torque * the rpm you got it at) / 5252

i think 5252 is right.

its up to you if you want nice topend and more horsepower but not so hot bottom end



you might lose 1-2whp on the dyno by pushing your tq down in the rpm range.

but really that could be dyno error
