Thread: 5sfte exhaust

  1. #1

    Default 5sfte exhaust

    I need to know what size exhaust piping to run for a 5sfte. Is 2.25" too small for running around 5-8psi on a 5sfte?

    If you have it, that's fine. Best exhaust is no exhaust, but at that power level, 2.5" is just fine.

    well i have a 5sfte im planning to run 2 1/2.. 21/4 is a little small but it will do, you will have to check your clearance under neath your car..and see if your piping will fit..just go and get the greddy sp exhaust.. that will work..

    There's plenty of room under a 5th g for 2 1/2. Or 3".
    Personally, I'd go with 3". It'll give you a little more oomph up top, which [I like better] on a fwd.

    You can always find out what bends and piping you will need and buy them from summitracing.com or jcwhitney.com, take them to an exhaust shop, and have them welded up. Just a thought

    Or buy a cheap 100 dollar welder, buy the pipe as mike said, and do it yourself. It's a good learning experience.

    im guessing the custom exhaust requires t304 steel because of hot temperatures? or can we get mild steel for this?

    I used aluminzed steel tubing from Summit Racing. I see no point in going to stainless or aluminum.

    the local shop here did my exhaust for $300 from the downpipe back. they put flexpipe in and a highflow cat no res. all the pipe is 2.5" and mandrel bent. sounds pretty mean. i wanted 3" but they didnt have the tools to bend it.

    2.5 is good for a 5sfTe because u if you ever have to take the turbo off, you will still have a good exhaust for the NA motor.

    srt4s run 2.25 stock and still put out over 200whp, so even that would be ok.

    brullen offers 2.5" catback exhaust, they recently came out, 500 dollars if you don't want to go through the hassle with custom.

    The Brullen has been around for years actually. I've had mine on for almost a year and a half. Its completely customized to what you want. You tell them the piping size, muffler style, and whether you want the loud or quiet version. It takes a few weeks to get it in, but its worth the wait. Its all stainless except for the flanges which are mild steel but they are thick plus it has a lifetime warranty so thats not a problem. It fit perfect, and I didn't have any clearance issues. The only thing is, its made for cars with 2 cats, and it ends about in the middle of the car, so you will have to get someone to make you a midpipe.I just ended up buying a welder too, cause they wanted to charge me like an arm and a leg to rent one.

    Thats funny because if you go here: http://www.autoaccessorystore.com/ho...at=7&sub_id=23 they don't ask you for piping size and all that bs.

    I got mine from Performance Parts Specialists: http://www.ppsonline.net/brullen.htm#cat

    They list some of the options on the site. Maybe the reason that its so much cheaper is it only comes in one configuration and the one from PPS is an extra 200 to have it customized. It seems their website is down right now, but they have more details @ http://www.brullenexhaust.com

    If i got a downpipe from a 3sgte, would it meet directly with my existing exhaust pipe? And I'm guessing the flanges are different.

    The stock 5sfe exhaust flange will not mate with the 3sgte dp

    you can get a 3sgte midpipe, and a 3sgte catback and that will be a plug and play solution

    if you go to alltrac.net and check out their tuning section, exhausts you'll see the midpipes i'm talking about.

    My 5sfte was 2.25" piping with 2.5" mufflers (the muffler place didn't want to go through the trouble of fitting 2.5" under the oil pan betwen it and the xmember (it's a tight fit). Sounded alright, and made decent power.

    If i were to do it again i'd do 2.5" but that's also because if i did it again i wouldn't shoot for anything below 250 crank hp, more realistically around 300chp.

    As far as crushed vs manderel. If you're in the 2.5"+ piping size it really shouldn't make that big a difference in the piping size. manderel will definately make more power gains at lower rpms because of the smootheness of the pipe...but when it comes to peak power i've seen a few cases where going from a crush bent 2.5" to a manderel 2.5" with a peak gain of only 2-3hp.

    When the pipe is that big crushing it for a slight bend is no big deal. However, manderel is really not htat expensive, and it's something you're only going to buy once...so if you plan on keaping the car for a while do it right and forget about it.

    If you go drag racing at the track on weekends then i think the cutout is the best setup. you can keep low boost/quiet exhaust for your daily commute... then when time comes to go all out, put your race gas in, turn up your boost, run an open dp, take off your 3" airfilter and put on a 3" velocity stack and let it rip ...

    so all in all : )... i've given you 3 different recommendations ... it really comes down to who you are and what your goals/uses are for the car

    So your telling me if I were to do a 5sfte and went for an all out all-trac exhaust system, lets say aussie 3" dp and midpipe with an HKS catback, everything would be plug and play?

    i don't see why not. I don't know anybody that has tried it personally (i'm sure there maybe). But if anything , there is more room under a FWD celica than there is under an AWD celica.

    The 5s and 3s sit the same way on both cars. The dp will exit the same way. The oil pan is shaped hte same way ...once you get past the front end of the car there is quite literally nothing back there but some fuel lines and the fuel tank.
