whats the firs step i should take? im budgeting at about 300 bux. what will i get more power from and what brand is in my price range?

Well 2 things.. 1 you can check the buyers guide on intakes on exhausts. Just look at the top of the forum Scion xa/xb Drivetrain and Power. That should help you out.

Im also looking at intake and exhaust. Intake im thinking the Injen Short ram series that normally runs 160-170. And im getting the Strup axleback exhaust.

Normally people run intake and then get exhaust...But either one first would work, your call.

If you only got $300.00 bucks an axle back is probably going to be a lil over 300.

i really appreciate ur advice and what do you think of fujita short ram intake or do you like injen better

fujita and injen are pretty much the same product just different name

I got my Injen SRI for $160 and my Magnaflow Catback for $150. Everyone on here is buying full stainless sytems. I just went down to Master Muffler and Brake, picked out a muffler and tip and told them I wanted 2 1/4 piping from the cat back. Done. I also later installed a silencer that was like an extra $50. Although my whole exhaust isn't stainless, the important parts are; the muffler and the tip. Plus I got the performance of a stainless catback for half the price.

an exhaust should net more gains. When looking at performance products ask yourself why didnt the factory do it that way?
The factory intake isnt that restrictive on these cars, theres no reason for it to be, but the exhaust on the ther hand has to be to be quiet, cheap and have a cat for emmisions reasons. So power is to be had in the exhaust and removing the cat.

For $300 you can have both.

Get yourself a Fujita F5 short ram. You can get it for $150 from many online stores, and as low as $119 off of ebay. The design is similar to Injen, but has better location for the vent line (after the MAF). Not to mention the lower price.

For the exhaust find your local Magnaflow dealer. Take your car to them and tell them you wasn a 2 1/4" cat-back exhaust using a glasspack for a resonator and a Magnaflow muffler with your choice of tip. You can also have them use the trick that Stylis does of running the glass pack in reverse so that it doesn't decrease the flow as much.

At the very most, I would expect you could get both of these done for under $350. And that includes pretty expensive labor and pricing from your local muffler shop.

Get them both like me and ^^^ said.

i'm getting the strup v2.0 and the k&n typhoon intake. the exhaust i will do myself and the intake i will try to to myself. terribleted recommended the intake so i will get that cuz he's a professional.

I have the perrin intake. No regrets, it made a huge difference in the way the box drives. Honest advice, go with an intake from a reputable company and you will be happy. If you go off brand you could run in to craftmanship and fitment issues.

I would get an intake. I have an Injen Short Ram and it is awesome. The xB is still no where near "fast" but it was definately noticeable that the box was breathing better.

Have you considered a pulley? I felt the most seat of the pants gains when I installed my pulley.

pulleys are bad. If you want more info pm me.

Please share here. If they are that bad, I think everyone would like to see.

even toyota says they are bad in there engineering publications.

there are no harmonic dampeners available for these cars as of now. All the aftermarket pulleys are balanced one piece units that do not include a rubber dampener. The rubber dampener absorbs harmonic(measured in hz frequency) vibrations(ones you cant even feel) that cause engine damage. This has been proven over and over again. Every peice of metal has a frequency at which it will fail. Even large structurs such as bridges have failed because of improper harmonic isolation.

And pulleys cannot incease hp, its not physically possible. Dyno a car with a stock flywheel then dyno it again with a much lighter weight flywheel (an exagerated pulley for example) they amount of power generated is the same. Once the engine gains inertia it is no longer fighting the miniscul weight of the pulley/flywheel whatever you lighten. It will help your engine rev faster but that isnt always a good thing as it will rev down just as fast and loses inertia making it feel faster when in actuality you are not.
If there were power to gain from this toyota would have done it from the factory.

Well where the hell is the TRD turbo kit for the xB?? haha ...just figured I'd be difficult
I won't even go near a light weight pulley...I've read all the horror story posts on here and don't want any part of that.

ive heard trd offers turbo kits for the euro market not sure if its true tho. Somebody should import if this is the case. Either way zpi's picking up the slack! turbo turbo turbo!

That's good information redwar1441, but I'm still not convinced it's that bad on the little XB engine. There is another post where many of us dug up as much information as possible and added many many opinions and experiences. In the end we almost came to the agreement that a pulley wouldn't be that bad on a non-forced induction 1NZ-FE because it's so small, has so little power, and isn't a super high revver. The bad news from pulley's always seems to come with larger, higher power engines that are being used for racing or driven very hard on a regular basis. The average person who only wants the pulley for a little spirited driving now and then probably wouldn't notice any problems unless they were going to try and get extreme mileage from the box. If I only get 250K out of my engine instead of 300K+, it's still worth it because it's so much more fun to drive. The pulley made a big difference in the way the car feels while accelerating.

then why do motorcycle engines have counterbalancers? they're small too.

How do I know where a local Magnaflow dealer is? I really want power increase as well as MPG. However, none of the intakes for the 06 xB are CARB legal.

Thus I think I may have to get my power from the exhaust, please provide more information and I will definately get some power. XD Thanks!

Any place that installs mufflers and does exhaust is most likely a Magnaflow dealer.

then why do motorcycle engines have counterbalancers? they're small too.

Because they redline at 14000 RPM.

Thanks, I also got another question...

How does the power compare to the power increase of an intake? Also, is this CARB legal?

EDIT: Also, how should I ask the local shop about this? I don't want to walk in and look like an idiot. :nails: Please advise.

We're going to be at this for a long time at this rate. :P

The V-45 configuration is known for it's inhernet vibration.

How much power does the Custom Magnaflow 2 1/4" w/ glass resonator add?

Also, how does it sound?

I am going with the Strup ehxaust (about $275 + free shipping, just search online) and i got and Injen knockoff short air ram intake on ebay for $30. I haven't had the exhaust installed yet, but I can tell you the intake does add jump to the engine. And it is an easy install. Just follow the TECH article on here. I did mine in 45 min.

TPR magazine dyno'd intakes and exhausts for our engines. The biggest gain was with an intake netting about 8hp and 9 ft/lbs torque.

All the axle back exhausts they tested netted only 1-2 hp. The only exhaust that made a bit more power was a cat-back but even they said it was pretty obnoxious and not worth it.

Next issue they will show test results of headers.

Bottom line: Intake is propably the best bang for the buck. Exhaust is more style than power.

do a header and a intake! I think that would be the way to go.... I had the dc axel back for 2 months..... well I loved it untill I drove for more than 20 minutes.

I just installed my Strup Axel-back exhaust. I am not sure if it is because of my short air ram being on 1st or not, but I really cannot "feel" any power gain from it. Headers would be nice, but I have heard froma few that if you don't have an exhaust that can freely let the air flow out, you will not get the full benifit that the header has to offer.

Opps, forgot to mention, the sound of the Strup exhaust is excellent. I drove all over the place and had no problems with the sound.
