hey whats up everyone. right now im riding with open headers that i just installed and i need advice on what i should do for my exhaust. im wondering what would be best, like if i should leave my regular diameter of my piping or get 2.5? and if i should keep my old cat or get a high flow cat(would it make a diff?). really need some opinions on what would be best to gain some horse power. thanks
advice needed on exhaust - 6G Celicas Forums

on a ST, i would go with 2.25, maybe 2.5 if your planning more mods down the road.

2.25 and a High flow cat would work out great if your in a state that requires emission laws. If your not you can go without a cat, but that would make you a polluter. JDM motors don't require cats I think?
As far as exhaust goes, you can have a fart canon or a regular silent muffler.
I think the fart canon gets annoying after a while and it makes your car ricey.
It does however make your car stand out tho.....

my state doesn't require to have a cat but the reason why i wanted a high flow cat was because i hear around that 4 cylinders need back pressure or else i'll lose some horse power.. and for the next thing and last thing i'll do is a performance chip to the engine

that is a myth.
there are no "chips" for our ECUs, that work.

damn had no clue, what else could i do to my engine without adding a turbo or swapping it out?
u can buy a SRI (Short Ram Intake)
there are some that are made for our car on eBay for about $15.99 plus shipping, total comes out to about $35-$40. some sell for less, some for more, just depends. but the filters that ususally come with it are pretty cheap, so upgrade it to a K&N filter.
its possible to get a CAI (Cold Air Intake) but they aren't that easy to come by for our cars. some just use pipings from other makes n models n fabricate them so that they fit into our engine bay. but the difference in HP for us isn't significant, as the 7afe was built as an economy engine.
or, u can buy a drop in air filter that simply replaces the factory filter with a more free flowing filter. those are availible by K&N as well and work to help out, but i believe that with a SRI you can have a lil more throttle reponse than with the factory setup.

Pandelica 2.0 in progress.
u can get an Injen CAI or an Accord CAI, or just fabricate one urself 
You say you don't understand how we go dumb, but have you ever been where i'm from?-=-] Livin it in tha bay's a lil different [-=-
already got a SRI, thanks though 
getting my 2.25 highflow catback 2morrow. thanks everyone

well finnaly got my exhaust done. and it sounds great has a nice hum to it. decided to get 2.5 mandrel bent with a test pipe resonator instead of a cat. ganna do some big mods down the road. thanks again guys
take the cat off you wont believe the difference yes you need back pressure but cat removal makes it alot more responsive mine only goes back on for mot
