Kwickslvr,
A properly designed and fabricated header/exhaust will give substantially more HP gain than ANY other N/A bolt on even on a 1.5L engine (displacement makes no difference)! So far there is no header on the market that meets the actual requirements of this engine, they are all too short with poor collector designs. They were made to fit easily with stock exhaust-a convienence header not a performance header. The DC and ELP headers are well constructed but don't make much power due to the design constraints they placed on the development (it must mate to the stock pipe/cat).
Until someone throws the stock system in the dumpster and designs, fabricates and develops a header/exhaust from port to bumper we will have only CRAP (from a HP aspect) to bolt on. Here's the problem- multiple prototypes and dyno time to develope a header/exhaust correctly = big $$$ = little return on investment. It's all about $$$.

I have to disagree, % wise the gains would be the same if the header/exhaust was designed and developed correctly.
The Stylis manifold back system is good for the available headers but those headers are a very poor design. A correctly designed system would require the cat and resonator to be repositioned farther aft to make room for the appropriate length primary pipes and modern collector design.
The xB has plenty of room for a good header, as does my xA. It would not be able to bolt to the stock exhaust which is a requirement for the current production headers. The average car owner wants something easy which is not what they really need.
Do some serious reasearch on header design and talk to some of the state-of-the-art header designers/fabricators and you will learn much..... I sure did.

3 WHP gained on a 1.5L is a much bigger deal compared to 3 WHP on a 5.7L so if I gained a mere 3 WHP on my dinky 1.5L I'll consider that as much an accomplishment compared to 30WHP on a 5.7L.

The truth is...
The VVTI 1.5, really only puts out only about 85 to 88 hp. at the wheels.. the car company takes it figures from the flywheel.. The tranmissions soak up about tweenty or so hp. thenadd in AC, power stering, altenator, and the numbers drop lower from there.. 108 horse power is the hook to draw you into buying the car..along with other features and so on .. The TRD products have always been to way expensive for what they are.Unless your sponsored by Trd or toyota,scion.. why evn bother unless money is no obeject. but if thats the case you would be most likey driving something much more expensive.. Its only a dam F#@$%&* econo BOX for christ sake its not a celica or a supra... or a race car.. its just a cool people mover.. not a horse power monster it will never be one etheir... The mild street product that are produced are for improving proformance with in the emisions limts.. If the moter is capable of tunning to 225 hp. at the wheels the emissions would go through the roof.. Race tuned headers can be designed.. but in order to really gain hp. you need to do a lot more than mild street tuned bolt on parts.. Im not saying bolt on parts are bad in fact they work in some cases better than stock. bottom line here is that its a buyers market spend your limted dollars carefully......... XBs for ever... :twisted:

Sorry to dissapoint you but Scions often put out 95hp at the wheels, stock. The trans does NOT soak up 20hp even on the automatic.
As far as emissions vs power- full throttle hp has no effect on emissions out put as far as the law goes because they don't test that at all.
I think 150hp naturally aspriated is a reasonable target for this engine and it could still pass the smog test.... well except for the AFC....
150hp in a xA would be extremely fun!!!

I'd pay $800.00 for a header that you guys don't wann buy. Why? BRAGGIN RIGHTS! :D While everyone gets a DC Sports of EL Prototype header I'll get the rare header to match my rare exhaust.

TRD, worth the cost?
I have to agree with Kevin, I would rather pay alittle extra and get the TRD parts at least for the engine and suspension upgrades. Why? Don't want to take the chance of loosing the warranties because someone is being **** about my upgrades. I mean, I'm putting in racing seats, audio/visual stuff, and some other interior work. I want to have fun with it, and not worry about it. Plus, TRD logos look plain sweet, don't ya think? Wild Bill

headers on xb
just got done installing a set of dc sports headers and borla rear exhaust (claim to be catback ?) . anyway! after insatalling them on my wifes anemic thunder cloud it woke it right up!!! no hesitation anymore and much more hp.will be instaling an aem cold air intake tommorrow (6/15/04).i did the work myself (24 minutes to r & r exhaust,70 minutes to r & r headers.very easy to do with hand tools.wife is very happy now that she has passing power.as soon as TRD comes out with a supercharger for xb its going on. cost of headers,borla exhaust ,and aem cai $625.00.can't wait to finish all the upgrades on hers so i can start on my hot lava # 1886.
does anyone know if the 2.4L TC motor will fit in the xB??
thanks,HDroar
upgrades so far to my wifes thunder cloud (cosmo);
dcsports headders
borla catback exhaust
18 x 7.5 panter chrome wheels
w/khumo exsta 215/35/18
strut tower brace

blue neon mid lower int panels
optx blue neon undercar kit
blue leds in cupholders, front &
rear
blue sport pedals
door sill enhancements f & r
floor mats and cargo mat
