swappers, what did you do for exhaust? Options

[brianforster]

now we all know that 3" is pretty standard for all our swappers.

what did you do for exhaust? custom from a shop close to you? make it on your own?

whatd the shop quote you?

how much was it if you did it yourself?

looking for general price quotes here, trying to plan out the finishing touches of the swap and the only exhaust shop i called said "theyd have to look at the car".

to cut down on costs i think im going to buy my own cat and muffler from summit (43 bucks for cat, 18 bucks for muffler, summit turbo muflers for the win!) i just wanna know if you guys have any idea what it will cost. i already have a downpipe.

i tried searching, but everyone just says they have 3" exhaust, not where or how they aquired it, and since they are all custom, was wondering what everyone did for it!

thanks as always

we've already established shorter is better? thats what we all agree on....

"it is easy to get overeager on fitting large-diameter pipes into an exhaust system. "the larger the better" is not always the case....there is an exhaust gas velocity that ought NOT TO BE EXCEEDED, this velocity is approximately 250 ft/sec.....to size a tailpipe, you can adhere to this exhaust gas velocity or to simple the guildeline of selecting a tube diameter approx. 10% larger then the turbine outlet diameter."

a 3sgte @ 15psi makes 321cfm ruffly
just to make sure i'm correct
i got it by....((122.04cid x 5000rpm x .5stroke x .90ve)/1728)x(14.7x15/14.7) = 321cfm

a 2.5" pipe can flow more then 600cfm(ruffly 293ft.sec) adiquetly
but we all know that a 3" exhaust does prove gains over a 2.5"
but at the point of 4" it would seem too large for a celica
