Now that my interior, exterior mods are done for now, I want to add a little more zip to the box. I'm not looking for anything ridiculous like a supercharger, but something more feasible, and not an insane amount to buy.
Thanks.

The cheapest... unbolt your exhaust from the axle, back... :D

A grounding kit will get rid of the annoying fluctuating RPMs at idle but don't provide any noticeable hp difference.

A cai will provide a lil more torque, and change the sound of your exhaust slightly, but don't expect too much.

An exhaust may free up a couple of ponies, but you won't notice anything.

With new headers and exhaust, you may feel a slight difference, but once you get used to it, you'll think that all it did was change the sound of your exhaust.

You may want to just put the $$ into other mods...

In one of the magazine xB dyno tests, they dropped the exhaust at the axle and the car LOST 3 hp...

Well... it's still a 3 hp difference!! Gotta be worth something... Not everybody wants a 110hp beast. lol

Nexus's header (www.alphawerks.com) picks up 4hp at the wheels...thats about a 5% increase!

intake headers and exhaust will help good air in bad air out. N2O works great stick with a dry system and you should be just fine

just go for a intake, header, and catback exhaust system... thats prob around 120ish hp all for under 1000 (not including install price)

I'd say 12hp from intake, axle back, and header might be a little on the high side, but I think you got it covered by saying "120ish" :lol:

In all honesty, I'd expect to see ~8-12hp from these mods. A full 2" catback might get you closer to that +12hp range. Will you feel 12hp? Hell yes! You'd probably get a little better mpg, too.

injen short ram 4WHP, DC header 6-8WHP, good catback system 8 whp. from the numbers i have seen atleast, with a good catback system good intake and good header 20 hp to the wheels is definatly possible, so your looking at like 110-115 horse at the wheels with this car, hahahaha booo for the 1nz

Listen I know the xB isn't a racer, I just would like a "little" more. Not 50 more ponies, but a few.

K&N's typhoon intake improves HP by 8.1 hp... which is MORE than a complete exhaust system will add (header, high flow cat, and catback) look at peoples dyno results... not much room for improvement over the stock exhaust other than making it louder.

I have a 2000 Echo that runs the same motor, I have a open air filter, pulled out the baffle in the airbox, run 91 oct. gas, synthetic tranny oil, and I have run Mobil 1 Zero w-30 for 70,000 miles with no problems. The oil made the engine come alive!

8.1 horsepower......dynos rate 3 at the wheels.

Yep, the K&N isn't really better than any other intake. It's all up to where you'd like the intake to be...
I've driven an AT xB with a K&N and it still felt slower than mine.
The best mod you can do to feel like you're a bit less slow is have a MT.

Typhoon it is. Did you buy it from K&N, or somewhere else?

I agree with K&N 100%...and their service is matched by none!

For what one has to pay, the gains aren't that great.

That depends on your POV. I just paid $200 for an Injen CAI and if I could get the same gains again for that price, I'd slap down the 2 bills right now.

I'm not concerned with peak hp gains, it's what it does over the whole powerband that I care about. The increase in response at low rpms, from a stop and the increase in acceleration that allows me to give less pedal for the same acceleration is key to me. Plus, it's saving me a little gas without me having to slow my driving habits...

Really thinking about that header now...
