I'm about to have this done to my 94 ST! I ordered headers, a cherry bomb (glasspack style) resonator, and a high flow muffler canister style with a 4in tip (burnt) but I'm using a 2.5in piping mandrel bent from the headers back with no cat. I'm looking to have a nice deep throaty tone and be very loud!!!
:D I will post pics of the before and after and maybe a video if it sounds decent on camera.

i have heard even material of the header makes a difference, cheap stainless steel won't sound as good as DC headers for example. I think he meant to add a cat later, although the cats main purpose is for emissions, it does assist with the overall sound of the exhaust.
Okay so my question to you... if it were you, would you get a header and if so what brand? I've heard of DC but do they make headers for the 7A-FE. And can you add a cat. to a custom exhaust, I mean you can but how does it work?

Are you trying to gain more power by re-working your exhaust system and getting a header, or are you just looking for more sound? I would be careful opening up the exhaust too much on an st or any n/a motor for that matter because you will lose lower end power and torque
Getting an aftermarket header also will eliminate the factory catalytic convertor which could cause issues passing emissions tests and having local exhaust shops touch your car because it's technically illegal to remove the cat from it's factory location. I have a 94 st that I put a header on and greddy exhaust back in high school and didn't really see any noticeable gains. Car sounds good though
BonzaiCelica
May 18, 2011 - 7:39 PM
yes you will lose power down low the st only outputs a weak 115hp with a full exhaust and intake. Most Japanese Exhausts (for the ST202 with 177hp and ST202 SS-III with 197hp naturally aspirated engines) come in 60.5mm exhaust piping. Anything bigger than that and you would lose some torque and gain top end
I've read that some Integra Type R guys have used 2.5 inch catalytic back exhaust systems with good results, I have not seen any dyno videos of this so you'll have to do your own research.

i would stick with a 2.25, that 7afe just don't put out enough, in fact a 2.5" on a 5sfe is a little too big, switches the power too far to the right instead of improving midrange. if you got like cams on a 5sfe or a decent built one it would be good though.

its alright on a type r cus they push out decent power without having to lose torque as much as a 7afe would down low, which the 7afe is already low torque.

Wow an old thread, just going back on a bit of history, at the time I thought 3S-GE were equipped with 2.5 inch they are actually 2 inch I don't know why I thought 2.5. Even my GT4 originally had 2" after the cat and thru the flexi, and then onto a 3" aftermarket system.
I have 3" from the back of my turbo to the tail pipe now with just 2 resonators and a canister in the rear, no cats or bull**** small pipes.
cyprus_gt
May 19, 2011 - 12:17 PM
So i got JDM st202 with 3SGE (ss2)...original have 2 inch pipes....
....so i change to HKS manifold and HKS downpipe (wrap them both) plus Magnaflow high flow cat. magnaflow resonator and Magnaflow street version Mufler - all pipes are on 2,25 inch
Results:
minuses: the car i is to loud and my low and middle torque just dissapear
pluses: car goes better on high RPM!
so for me i spend so much money for little more power on high RPM but the middle torque miss me so much!!!
I don't recomend bigger pipes to car with less power than 200hp....
cheers
Dimitri
p.s.
thinking to change my backbox mufler with Apexi SW2 (wich is bigger than magnaflow one) and the resonator after the cat with 1140 Vibrant Performance Ultra Quiet Resonator so i can get back some of my backpresure....and low and middle torque.....

^ its true its the pros and cons of the exhaust setup. if you like torque don't upgrade if you like performance on the top end, then upgrade. You win races more with the powerband moved to the right, but it still needs to be balanced with some torque. Straightflow lets you stay longer in 3rd and 4th gear. I went back from 2.5 to 2.25 and now I have some midrange torque back.
BonzaiCelica
May 20, 2011 - 2:24 AM
you need a engine swap badly trd proven jus sayin
on the other hand I got this information from the beams owners group :
3" = 275 to 425 HP
2.5" = 225 to 275 HP
2.375" (60mm) = 200 to 225 HP
2.25" = 175 to 200 HP
2" = 125 to 175 HP
These are just 'general' guidelines, routing/bends/mufflers/etc will all change how the system will actually work out. So 2.25" using nice mandrels and good flowing mufflers/cats/etc would be perfect for a stock motor, 2.375"/60mm very good and not so big that you would see much in the way of losses and would be great for lightly modified engines. 2.5" is good if you have plans to modify a little more heavily and/or are going to use it as a track car.
Exhaust sizing doesn't make horsepower. It keeps you from LOOSING horsepower due to restriction. Your looking for a balance that keeps the exhaust gasses/air FLOWING at an ideal speed (around 240-260 FPS IIRC).
Too small restricts it by choking flow off at high RPM.
Too large slows it down by having too much room for the exhaust gasses to expand, which creates a slow moving 'wall' of exhaust.

that is a good set up mind you like the oval styled canister. the tanabe would be a good choice too since ive heard them and they are pretty quiet. but yea, just get the ultra quiet resonator the oval style and the longest you can find to keep the noise down. If you are running catless or doublecatless if cali model, you can always double up on the resonator later. but your original set up is ideal and will be deep but running catless makes the change. but whatever sound you want you can get, it can be adjusted for sound, with resonators. its the deepness you can't adjust, thats the muffler.
you have no worries about the pipe sizes being different, you can even go from 2.25 and switch up to 2.5. so 2.3 is a smaller change from 2.25.

My JDM celica wtih 3SGE SSII engine have final exhaust setup:
Wraped HKS manifold with HKS downpipe (second hand from Japan):
Magnaflow Heavy metal high flow catalyctic series 9900:
Vibrant utra quiet resonator:
and at the end Apexi WS2 muffler:
All pipes are on 2,25" (only the muffler is on 2,37")
Tomorow will test the car and will let you know for the result!
cheers
p.s.
my last setup was:
the same HKS manifold and downpipe + diff. model (small one) high flow Magnaflow catalyctic + no name resonator (local one) + magnaflow street Muffler (all at 2,25")!
minuses : i thing becouse of the catalyctic and the muffler the noise is to loud and the low to middle torque has gone!
pluses: the car goes crazy after 4600 RPM :-) good sound when you drive slowly (sound like V6)
so that why i make new configuration - to reduce the voice from the exhaust ang get back some of the middle torque with the new toys

The car now have more noise from the stock one but you can enjoy it driving slow or fast!!!Only some to deep sound it's show up after 150 km/h on the highway on full throttle but its coming from the manifold and the catalyctic wich is normal - the flow is high...

Damn cyprus, that sounds mean as hell, great job, glad you liked the setup. and the parts look real nice. and you're right the sound is usually better in person. I've compared many combinations of different engines, piping, muffler, resonator, so I know what sounds good. Other people just like to get whatever and put it on. In fact, someone else prolly would have gotten the bottle style resonator instead of the ultraquiet one.
But Bonzai to answer your comment about me needing an engine swap been thinking about it for a very long time or doing a turbo on my 5s, but right now I am working on my 7th gen Celica, i just threw in 6 grand into it so far cash, and I am working on my offroad tacoma. I have too many hobbies, can't afford everything. I am buying a house very soon and just cashed out my wedding earlier this year. I plan to get me a Supra next year if all goes well and thats where my performance efforts will be placed or a similar toyota with rwd potential. I've had 3 generations of celicas and I used to have 2 fliplight supras but since I really wanted the last gen Supra since I was a kid, i am trying to save money for it for next year. I bet everyone here has wondered why I never did a swap. because I decided to get a RWD, which has always been my ultimate goal. I'm also going to get a IS250 or 350 early next year as well. I have money already put aside for that, i need a 4 door car badly.

I'm pretty much new to the whole exhaust area, but I recently picked up and ebay header for the 5s and I have a brand new flex pipe with a cat-delete already on it. Now my question is what would be the best setup to make it purr at idle, but roar at high rpm's like cyprus_gt's? I have almost brand new flanges in the rear where the stock piping goes over axle, but at the same time I just want to get new piping altogether in the rear. I know if I get a can, it will be loud no matter what because it doesn't muffle the noise like a muffler does, but if I go under axle, could I still get a muffler that sits even and not crooked? If someone could help me out, I'd really appreciate it!

Tig welded with 308l filler rod (309l where it mates to the non stainless cutout) all the pipes were coated in the weld areas with solar flux on the inside, so the welds will not rust.

can I ask what is wrong with the Factory extractors? Because your wanting to spend about US$850 for 1.1KW? The factory extractor type manifolds fitted the 3S-GE and BEAMS 3S-GE are very good. Toyota put some effort into the design and flow of these.
I think your better off putting your money towards your BEAMS engine.
rusty is right, there isnt a lot wrong with the stock extractors, the dimensions may be quite tight but they are fine for a near stock cam, the problem is and this is typical toyota the ingredients are right, the execution not so, the welds tend to be tack welds on the outside and welded on the inside, if you reweld the manifold so the welds are on the outside of the pipe, take a dremel and grind out the garbage on the inside of the pipe, so far i've found the manifolds to be really sloppy here, the design is fundementally fine, but the execution is poor. This isnt a power adder as such but will free up the engine at high revs, we found this on the beams and its also true of the newer 2zz engines where usually a ported stock manifold is better than the aftermarket ones.
To make it complicated
It is worth leaving a step though at the bottom of the manifold floor where the manifold meets the head, you dont want it exact you want the pipe to be slightly bigger at the floor so there is a step down leaving the head, this helps to break up reversion pulses and does no harm to the exhaust flow.
another thing I don't understand is the last paragraph edophus spoke of?????
