I am looking to spend a little money on my 06 XB, (it is a manual) and did not know wether to go with a short ram intake, a cold air intake, or some type of exhaust. What have you guys done and what do you think would give me the most increase in power for under $500. I am just looking to not get beat in drags by freaking honda civics. Any sugestions would be greatly appreciated. :bow: :pray:

intake, dc sports header, cat back exhaust, or even just an axle back might help a little by having less backpressure overall. light weight crank pulley.

Iwould say SRI and an axle back exhaust for $500. This will add a little hp to your ride and give it a great sound to. Once you get more money to spend then get a header and a light weight pulley. If you had more than $500 then get the cat-back exhaust well worth the extra dough. Just my opinion. Spend your money well young jedi (lol) and once you start modding you'll never be able to stop, it's alot like crack. Good luck

oh yeah, get urself a nice aem intake and some headers.

if you guys could be a little meore specific on what brand/model of intake and exhaust it would be great i am looking at buying this stuff this weekend. Would a catback exhaust be bolt on like a axel back or would i have to weld because i dont know how. and dont feel like geting riped off by a shop.

Injen SRI, precision muffler axle back or magnaflow cat back, DC Sports header and a perrin lighweight crank pulley. I beleive the cat back does just bolt on, you just have to cut the exhaust right before the cat. But i will find out exactly for you. Hope this helps. All are do it your self projects with the right knowledge and tools.

AEM intake I got mine from www.NOPI.com, DC sports header www.ptuning.com, light weight crank pulley www.perrinperformance.com, then once you get some more cash get an exhaust.

Thanx everyone, I was going to ask same exact question, I LOVE this forum!!!

If you spend your $ carefully, you can get headers, exhaust, intake AND a pulley for $500..

... light weight crank pulley.

This would the pulley for the belt? How much less does it weigh and what effect does this have?

I believe the Perrin is 2 lbs./stock around 10 lbs?? The box mine came in listed it @ 1.2 lbs, so right around that figure. Quicker revs & acceleration.

Has anyone dyno tested the"claimed" 2.7 hp gain for every pound shed from the stock pulley? HP gain just sounds too steep.

When I dyno'd my car with i/h/e pulley and camcom it was 106 at the wheels

A lighter pulley will make quicker throttle response. quicker revving in neutral, and possibly a very little quicker acceleration on the road -- from not having to accelerate the mass of the pulley. This is similar to lightening the mass of the car.

But neither lightening the car or the pulley is going to create additional horsepower.
These measures cannot add any horsepower to the engine's output because they do not affect the way the engine runs.

its not 10 lbs its more like 5lbs

I have been looking @ using a ZPI pulley instead of the Perrin...mainly because its lighter 1.1lbs...any of u guys used this pulley?

hmm why would you get and sri and no the rd cai isnt the rd better then the sri

aem aftermarket intake 200 shipped , megan header 130 shipped , exhaust as cheap ___ 100 , good cat back will be 200-300.

you can get a cheap intake for like 80 but....


a perrin pulley is also awesome , only 130 or so shipped

weapon r engien damper about 130 shipped. good.

so yeah pick n choose

Well im not sure what the rd stands for, but i did consider the AEM CAI for a long time because of the colder air into the engine which = more hp. But what scared me was the fear of hydrolocking the motor, FL gets a tone of rain and floods alot, and yes there is the bypass but just way to much for me to worry about. So i went with the SRI for its ease of install, easier on the wallet and not having to worry about submerging it. It's funny thou the Injen SRI is almost in the same spot on the drivers side in the fender as the AEM CAI is on the passenger side, but the SRI has way less pipe for the air to travel to the engine. And dont worry i got lots of hp now and plenty more on the way.........

There are a couple of ways to go about doing what you want to do. One way is to go as cheap as possible, and the other is to find the best deal on the parts you want.

To go cheap you can get a YDR intake, Megan header, custom axle back and an Agency Power Pulley for under $500.

If you need to maintain the $500 limit, and don't want to skimp on parts I would recommend the following in order...

Fujita F5 Short Ram Intake - $140 +/-
Strup or DC Header - $225-270
Your choice of axle Back - $300+/-
Agency Power Pulley - $130

You can really make your own decision as to what brands to buy. Just do plenty of research before you make a final decision. And keep in mind that you will get as many opinions on what to do as you do responses. Everyone has their own preferences, likes and dislikes.

Hey hotbox05, are these two iteams worth it. Cause i want some more power and im not sure if I want to get these.

I'm interested in getting more power, too. I don't want a loud ricey sound. Would I get a decent power boost with the header and intake only? With this setup will the stock muffler keep the noise down(not raspy)?

You will see a gain, but not as much as if you did the full i/h/e combo. Your stock exhaust will be somewhat of a bottle neck. (Not that you wouldn't still be bottlenecked with the stock down pipe, cat and exhaust before the axle.) Your best bet would be to look for a already quiet exhaust that is also available with a silencer.

I just looked up this up on ebay and here are my results:


Shortram Intake - $50
Lightweight pully - 100
4-2-1 headers - 140
Full Exhaust - 318

Total: 608

So i would save the extra 108 and just do everything at once... Might want a better filter for your intake as those cheap ones are always the best but still better than the stock for sure!

What do the above modifications do to your MPG?

If you can keep a tight leash on your "lead foot" these modifications can actually help with fuel efficiency. As long as your driving habits do not change, chances are you will see a mileage increase.

buy the lightened undrive pulley first, then go from there

Do not Underdrive. The potential for problems is more trouble than it is worth. Stay away from the Unorthodox and Non-Stop Tuning pulleys. You'll be much better off with a lightened pulley from Perrin, Agency Power or ZPI.

The stock header looks pretty good... has anyone seen any HP TQ gains from an after market one?

From what i've heard, you'll get the most gains from the header in the I/H/E combo.
