Hey guys! new to the forum, but not to the car, Found the after market finally for my Celica GT! Options

[UndecidedPC9397]

so as it says, I found this forum almost by mistake but found a thread with a black Celica that had been turbo'd and im back in the Celica groove. Im not thinking of really boosting the car... yet but I do what better exhaust and intake. im gonna attempt to go with that 90-93 accord CAI kit idea and get custom exhaust.
First thing I wanted to know is whos tuning Celicas in minnesota, cuz I would love to meet you guys. and also with my exhaust, I still need to find a fab shop to do my exhaust but I was think of doing a full custom exhaust (header to muffler) and wanted to know how much that might run and if anyone has done it with there 5S-FE? I have alot more things Id like to figure out (getting JDM tails, suspension, rims, etc.) but I wanna get this figured and get some rough numbers before anything else, because I hate that butt ugly stock exhaust manifold. Thank you

well, my forum friend.. interesting that you are looking at those choices.. i have been doing some research my self, and the exhaust that i will be going with for many reasons is a 2.5" header back, 304 SS. i too like the EvoII can, i fell in love with it when my brother had an Evo II exhaust for his 2000GTS (GReddy). unfortunately the unit is no longer available from greddy. but you can get one off Ebay from OBX (who looks like they picked up the design after greddy dropped it)..

the only issue that i take with the EVOII can is that large 4" tip on it..

For resonators i will be going with 2x of aeroturbine's AR25 resonators. (inline one after another in the mid pipe). i chose to go with a pair of this unit after reading a large number of reviews on a wide array of different platforms.(just Google "review aeroturbine AR25" and you will see what i mean) along with before and after sound clips..

now.. just to note that i have chosen to go this route on my exhaust setup because i will be going turbo on my lil 7AFE, and there is no way that i will max out a 2.5" exhaust.. the aeroturbine resonators are !true! 2.5" strait through designs. meaning if you measured the pipe that goes down the the inside of the it too is still 2.5" so there is little to no restriction from the resonators. this is not true of many of the other resonators on the market. the 304 SS has a great properties, lighter that mild/aluminized steal, great heat management, and an ok cost. (for SS)

also i will not be going with a cat, i may later, but my car has no need to ever be registered or inspected ever again.. (unless my parents move states) should i ever need to though, i will get a SS cased ceramic cored cat. they take a bit longer to light up, but they last allot longer than metal cored cats, especially when using E85. (i may have that backwards on the metal vs ceramic. but either way i will take the one that last longer, over the one that lights up quicker)

i will be doing a coat of ceramic black paint all along the exhaust, all the way up to the tip. aswell as Ti exhaust wrap. this will do the best to contain temps inside the exhaust (and thus reducing the temp drops and maintaining exhaust velocity) aswell as protecting the unit from foren elements. not to mention it will also not draw too much attention to the under side of the car from the rear (as in if a cop was pacing me)

to minimize the bends and provide maximum performance i will go with an under-axle set-up.. many celis are using this type of routing on a DD, and report next to no issues with it.

Yeah I want to do header back, But I want something better than my stock header which looks like crap to boot, should I get a camry 5sfe header or an ebay header? and why that grade of stainless steel? and if you go to a exhaust shop, is that an option you can request? And I live in minnesota where I know they dont do emission but I want to play it safe for right now. And are you gonna wrap the header or paint everything? and are you also painting the muffler?? and do the magnaflows have ceramic cores? and I do agree that tip is a bit bulbous but the main thing is it does the job, everybody has said good things about them. And your running two on a 7afe, what do you think would be better for my GT with a 5sfe? just go with one or should I aim for two? I really want to try to get the most power off NA that I can to challenge myself a bit and see what this engines potential is w/out a turbo but have it be tastefully done and sound really nice. And I know this is a bit of a noob question but do I need a flexpipe or can I ditch it? Im still very new to the car and tuner scene so im still trying to learn the basics.

Yeah I want to do header back, But I want something better than my stock header which looks like crap to boot, should I get a camry 5sfe header or an ebay header?
** they are one and the same.. just get an ebay header for the 5sfe. you will have to fab up a small section to match to the stock piping if you are just doing the header alone..if you are going to do it all at once then dont wory about it and just have the exhaust start at the end of the header.

and why that grade of stainless steel?
**last time i was looking at SS cost it was one of the cheapest, that may have changed now, but also alot of the parts (like the resonator) are made out of 304.

and if you go to a exhaust shop, is that an option you can request?
**most likely not. most exhaust shops only use mild/aluminised steal. and they use a crush bender to bend the pipes. you will probably have to find a "pro-shop" or some one who has a tig and knows how to use it.

And I live in minnesota where I know they dont do emission but I want to play it safe for right now.
** that is a good point, but if you have to cut on cost, u know where to do it now.. just leave some extra room behind the first flange so that you could always put a cat in later.

And are you gonna wrap the header or paint everything?
**for me i will do it in three steps. step 1: (since the cost of having it properly powder coated is quite high) i will be painting the whole thing w/ a hight temp ceramic black. Step 2: then wrap it with Ti type exhaust wrap. The fibers are made from crushed volcanic rock, and unlike regular fiberglass based exhaust wrap, do not need to be soaked in water to make em wrap tighter, and farther more will not slack when they get wet from rain/melted snow. AND the Ti wrap is supposed to offer better heat management. Step 3:a final coat of silicon based exhaust wrap paint (black) this will help "seal" the wrap from foren elements, and provide one more heat managing element to the exhaust.

Then and are you also painting the muffler??
** i will be painting mine from the header flange on the head, all the way back (up to) the tip. so if you look at my exhaust b4 install it will be all black but the tip (no jokes here) the tip i will keep polised. as for the exhaust wrap. that will go from the flange on the head, all the way back to the base of the muffler. alot of people only wrap up to the cat, or the axle, but i do not see the point on having any exhaust wrap at all unless you are going to manage the heat as far back as posible and due to the bulbus shape of the EVOII can, it will be too much of a hassle to try to keep the wrap on the can, so ill just stop a the base.

and do the magnaflows have ceramic cores?
** assuming that you are talking about the cat here, i'm sure that they do, i am not posative, but dont see why they would offer one without the other and an option.

and I do agree that tip is a bit bulbous but the main thing is it does the job, everybody has said good things about them.
** yes IMO one of the best sounding mufflers for a 4 banger!!!

And your running two on a 7afe,
** i will running two aeroturbine AR25 resonators in line, and an EVOII muffler at the end.

what do you think would be better for my GT with a 5sfe?just go with one or should I aim for two?
** that is purely up to you. depends on the sound that you are looking for.

I really want to try to get the most power off NA that I can to challenge myself a bit and see what this engines potential is w/out a turbo but have it be tastefully done and sound really nice.
**normaly what will sound nice will not always give the best performance. most of the concepts of sound deadining in and exhaust is based on the interuption or redirection of air flow. any time that you are changing the direction of air flow air will loose momentum and velocity, thus lose in power.. there is alot more to it, but that is a simple jist of it.

And I know this is a bit of a noob question but do I need a flexpipe or can I ditch it?
**KEEP it that one little piece can keep your exhaust from developing any number of leaks and cracks.

Im still very new to the car and tuner scene so im still trying to learn the basics.
** thats ok, just read, then read some more, then read even more!!! thats about all i do.. that wah when i have the money to spend on the car i feel much more confident in my abilities to do it with out screwing up compleatly on the first time around.
