The resonator is separate from the cat, and is somewhere before the muffler. It is NOT needed to pass emissions (I don't even think it affects it, just sound), but you will need a cat to do so.

i can't find what size the stock exhaust is for the 3sgte..
~Daniel~ No Longer Celica Owner.. moved on to a 03 WRX-EJ207

its small. IIRC its just under 2.5", and has compression spots where it goes over the crossmember.
a couple of pics of a custom b-pipe i made for dustins swap.
3" mandrel bent stainless, with the super cool exhaust cutout. (remote actuator not pictured)

What's the largest diameter exhaust you can run over the rear axle?
One o'dem crazy Canadian freaks, eh?
>
i've seen as large as 3" over the axle, but it takes a VERY good fabricator to make it work properly. (im not nearly that good yet....lol)
IMO anything larger than 2.5" shouldnt run over the axle, going that large,(3" or bigger..lol) with the bends it requires, IMO negates the advantages of having the larger pipe.
a couple pics of a downpipe and b-pipe i made for steffs turbo setup this weekend, to mount up to the greddy cat-back she got.(you can see where i added the v-band to the existing pipe laying behind the exhaust in the first pic.)
2.5" stainless mandrel bent, with custom turbo exhaust housing flange by randy (97lestyousay) and some super sweet vibrant v-band clamps. with those vbands, you get perfect alignment of the exhaust because the flanges have a male and female side to align them, and you also do not have to totally take them apart because of the cool snap together v-band that holds them together. ill get a couple pics of one that was left over later.

That pulled up pretty nice, the first pics I saw with the flange sitting on the turbo made the gap
look a little bigger.

Here is a clear explanation of each a resonator and catalytic converter as well as their function. (courtesy of carexhaust.com)
Catalytic Converter
As already mentioned, the catalytic converter reduces harmful emissions from engine exhaust. It uses a combination of heat and metals that act as catalysts. A catalyst is a metal (or chemical) that causes other chemicals to go through a reaction without being affected itself. The inside of the catalytic converter consists of metals like aluminum oxide, platinum palladium. These metals cause the carbon monoxide and hydrocarbons to react and produce water vapor and carbon dioxide which are much less harmful to the atmosphere.
Resonator
The muffler alone cannot always quiet all of the engine noise. Many car exhaust systems also include a resonator which is like a mini muffler. They are usually straight pipes filled with sound muffling materials. The resonator can be either before of after the muffler in the exhaust system.

ahh yea, i almost forgot..lol
here they are.
first the v-band and flanges together:
this 2nd one shows how the clamp part of the setup works. just loosen the lockbolt enough to slip the collar over the T part of the bolt, and the joint is ready to slip apart.
this pic shows the "female" (on the left) and "male" (on the right) sides of the 2 flanges. when you tighten the v-band, you get perfect alignment of the joint with this setup because of the nature if the design. good stuff IMO.
and lastly, the side of the flange that attaches to the pipe.
you can see in this pic how it has a "female" recess, for the 2.5" pipe to fit into a 1/16" or so, which makes for a nice tight fit for welding.
and a repost of the clamps in action on steff's (hurley97) custom downpipe/b-pipe i made here using them.
the PT # shown in the 1st pic is for 2.5" clamps.

she bought everything herself for her setup, im not sure what she paid to be honest...i know a 3"vband like that at the local speed shop is VERY expensive..like close to 80$.
PM me a price on the 3" vibrant vbands, ill be using a few of those in the hopfully near future on my own exhaust!
the 2 sensors are:
1 for the OEM pre cat sensor.
1 wideband / postcat sensor for stock ecu
she also has one farther down the exhaust path, after where the cat would go under the car.
im not sure if its an st, or 96+ thing, its the 1st and only 7afte ive worked on, to be honest...lol

Yeah V-bands are VERY expensive. The 3" complete set (clamp and two flanges) are $88.95 each from Vibrant, and they don't discount their stuff very much. I can get them for around $74 and probably work in some free shipping with a good order.

my dad said he would make me a sports exhaust for my car (hes made lots for his race bikes and such) so if he can weld all the piping and stuff what parts would I need to buy? i've also heard that I could use 3s-ge headers on my 5S-FE is this correct?
also because my car is a daily driver and I cant really take it off the road does anyone have "plans" or something like that of the exhaust for our cars? if it matters mine is a ST204

I pick up the car today from car shop!
The defective ebay header was pain in ass to fix..
Eheheh I recomend Headers and straigth pipe for everyone!!
The car response now is TOP!!
The sound is very loud when you hit the pedal
YEAHH I NEED to PUT ressonator very soon! I almost sure i got the loudest car in all town!!
I will put some video and pictures very soon!!
