Heres my situation..
I've decided to do the pipin for my celica...
I'm changing it from the standard piping to 2" or 2.25" but i'm unsure what to do..
As yet i just have a redback muffler and the rest of the system is stock... With just the redback muffler i am sittin on 87db...
Will 2" make much of a difference?
I would probably need a new resonator?? I"m considering going 2.25" for a deeper note but i don't wanna loose too much drivability but want a harder hit after TVIS, thats the fun zone.....
Could i get some opinions of benefits of 2" and 2.25"???
Would i need 2 resonators to keep the system down to 92db (the legal limit i believe)
Thanx again
Adrian

Found out from a friend that the stock system on the celica is 2" so no doubt 2.25" is the only option towards upgradin..
Could i still possibly get some opinions on how the car will compare to the stock 2" system supposably? and which areas will i feel the performance?

You will likely hear some more performance at the higher rev range 
Unfortunatley you wont feel the performance, the difference really wont be that great.
You will however "feel" the performance if you Run premium fuel and advance the ignition timing to 15 degress BTDC.
Please don't do this unless you run premium or ultimate fuel or you will likely destroy your engine!
I have run with 16 BTDC for a while now, and I use Premium 95/98 fuel.
Do this before the exhaust. Each mod will likely yield around 5KW, but the Timing adjustment will be "usable" and is free!
oh and i have the same car
