Subaru Stars 2005-2006 2.5I exaust question + few other questions

So I'm think about eather for a first car a Civic SI (2006) or a 06 2.5I (Trubo will be to much to insure.


So i'm likein' the 2.5...but i was wondring on the wrx since all the exaust systems sound really good dosnt even matter on the system..Would that be the same case on the 2.5's? even thoe it dosnt have a turbo and what not, would ohh lets say a HKS Carbon-Ti sound like it dose on the WRX or close to it? Or dose the turbo change the tone, and the 2.5 will sound like crap with a HKS Ti..(not saying i would be getting the Ti.)

and my other question, Would 2006 WRX/STi parts(Engine/Interior) fit on a 2006 2.5?

first off, definately go with a subaru!!! doesnt matter if its a turbo or not...
if you've driven a subaru you will know why its better

second, alot of the parts from WRX/STI are interchangable with the RS or 2.5I
for example, most interior and exterior parts, as well as alot of the suspension parts

however engine parts are different because they are really a different engine...
as for the exhaust, you can easily mate the WRX exhaust to fit the 2.5RS or 2.5I
i donno if it will ever sound exactly the same...once again they are 2 different engine
but you will definately fall in love with the boxer engine sound...

anyway...do your research... if you want to have alot of things to play around with the engine...WRX is your choice...RS have less option compare to WRX/STI...

you would not want to put anykind of STi/WRX exhaust systems on the N/A since they just are not desinged for an N/A motor. as far as sound I am sure YOU would like any system that will work for your car. Rallitek, obx (cheap and I was gonna get), and more. So I would just tell you to go get one and put it on you will not be disappointed. get some headers and an intake and you will be happy.

if you want you can buy my 05 RS which can already beat almost any SI.

Hes absolutly right man get the obx catback on ebay for like 400 shipped its the same as the cobb catback. about the sound of it. lets just say you'll love it. its got a nice deep rumble sounds almost the same as a rex but of course nothings gonna sound quite like a turbo.

dude.... I got like, a pack of baseball cards from my parents if my grades were good.....

Ask your parents if they want to adopt a well manared 23 year old who has one more semester left in college, maybe they can take me to the dealership too if my last semesters grades are good

Id consider myself lucky no matter what I got, but go with the Suby, and you wont be disapointed.

You can get that OBX for less than 300 buck shicpped. They have headers as well for only 300 bills. not a bad deal at all. Along with the injen intake and the perfect power you would be set. For your age that should be perfect.

Again if you want I can sel you mine if your in the area. Looking to get a 06 WRX very soon.

For exhaust Im running a Borla Header, stock cats, no resonator, 2.5" custom cat-back, and a Megan Racing M-SpecII canister and its a 05'.
CLICK HERE TO SEE VIDEO This is to give you an idea of what a n/a suby sounds like with a borla header and aftermarket muffler.

Just gotta wait a few more weeks, and we will know if i'll get lucky and get a Impreza. i'm working my ass off right now in school. hehe.

edit-Scubiesteve That sounds really nice. I'm going to do the same Setup :-p

Just got my 2.5i the other day now and have been doing a lot of research. If you want to put a stock STi axelback on it sounds pretty good, actually louder on our cars then the STi. I still havent decieded what i want since i just want a nice sound but not loud. I hate cops.

Secondly, for your 2.5i, PLEASE double check before going and blowing cash on headers. Why? Well prior to 06 everyone got headers cause they wanted equal length. Well guess what? 06's HAVE equal length headers from the factory. So, knowing that even if you did get some nice headers the gains are gonna be close to nill. Rather I'd spend 400 on a kartboy shortshifter (with bushings of course), front and rear cusco swaybars, and maybe a nice shiftknob. With just swaybars your gonna handle just as well as a WRX.

I love my 06 2.5i to death and its an absolute blast to drive. If you get one you're gonna love it to death.

with the injen intake, probably looking at slight gains, nothing more then 5hp. With the pp7, the last time i checked, rallitek still hasnt gotten a 2.5i in there testing bay to tune and develope maps for it. I know they have some for wrx and sti's and i know the gains are gonna be real nice on our cars, but who know until they can tune one.

I have an 05 RS
And I live in Chicago.
Getting the 2.5i will break your bank (as you said ur saving up money.)
And since this is (i'm assuming), your first (or at least one of your firsts) car, I'd say, keep it stock for at least a year. Break it in, get to know it before you start modding it. This way, you'll know if something goes at the least bit wrong. Whenever you are driving, try to feel the characteristics of the car. It is unlikely you'll ever reach the limits of the car, but at least you'll know what the car generally feels like.
After a year of savings, you should have enough money to do whatever you want to the car and you'll know what the car feels like.
Besides, the stock exhaust setup isn't so bad. You'll hear that engine growl anyway. I wonder if the 2.5i has the tinny non-grumbly sound since it has an EL Header...

5HP? Meh, here you go straight from INJEN granted its for a 2005 but I cant see the 06 being much different but I could be wrong

Now there's an interesting comparison.

The K20 in the civic SI is a neat little motor. between the RSX, TSX, and all the variations of honda/acura running that motor, they've got TONS of parts for it already. (motor wise) there's a ported style manifold that looks pretty massive that on a stock rsx is said to barely allow the stock hood to fit, and gains 30hp (dyno proven.) that's an interesting addition by itself for sure.

Just based on the shifter location alone in that car, I would vote for the subaru, but even if it had a properly placed shifter, I would still be biased to AWD, handling, torque (not high rpm hp) and four doors of comfort.

+1 for buying it and saving up for a while. bend the twisties and get an idea of how it handles. throw some springs, adjustable shocks, swaybar, trans mount, shifter bushings, exhaust, cold air, and it'll feel like a new car.

Why put so much $$ into a '06 2.5i? Wouldn't you be better off getting a WRX in the first place? Considering that mods void the warranty and that you might be spending a more on mods/headaces than the amount you saved by getting an RS instead of the wrx.

I'd understand wanting to mod an older RS but not an 05/06..
Is the amount you'll save on insurance/initial cost really worth the time/money spent on N/A mods? Maybe you should add up the costs of each option (+ any intangibles such as warranty value, etc) and consider financing a wrx instead. Do any of you with modded 05/06's regret not getting a wrx? .. or is it just me

^^ YES with the amount we save on our insurance, specially on younger people or people who get tickets quite often, it is WORTH it. If you call mods headaches then you obviously don't like workin on cars much. I don't regret not buying a WRX, I drove my friends stock WRX and boy that thing felt slow mostly cause i didn't really feel any low end torque and on top of that the turbo lag. I like the low end from the N/A motor, just gotta work on the top end a lil more... cams.

Also I have a CAi, Header, catback, and pulley and not once has my warranty been voided because of those. The only thing my warranty voided was my broken main shaft and 1st gear.

if i had the choice, I would get a WRX. but Insurance is where it will kill me. I'm not like the high school kids who parents buy them the car, and there parents also pay insruance.

I'm working 2 jobs to pay for the car, and the insruance. No one eles is going to help me out at all..It will make me feel i accomplished some thing more in life.

and yea, i would like an older rs, but i can't find any that are in a low enuf miles that will last me for more then 5 years.

you apparently havent driven the 06 2.5L WRX. The 2.5i is a joke compared to the power that thing makes. A simple AP tune and you are into the low to mid 13s quarter mile. The 2.5i cannot and will never hang with the wrx. It wasn't designed to. You pay for what you get.

im all for subaru and all...but i think there are alot more parts for the si then the 2.5i...but don't get me wrong, the 2.5i is a nice car. as for exhaust...you can pretty much get any exhaust and it'll sound nice...if you get unequal length headers, it gives it a nice rumble..of course not as power effecient as the equal lengths..the sti engine parts wont fit in the 2.5i (unless you do a sti motor swap..hahaha), but the interior parts should fit right in. just to give you my opinion, i would spend most of the money on suspension parts...it makes the drive a lot more fun.

Just to put my two cents in again. There were two cars when I got my RS. and 05rs and an 02 WRX. I got the rs since it had the 6cd changer and it only had 11k miles but the 02 only had 36k. Both were about the same price but if I would have known then what I know now the WRX is hands down a better deal. Oh most importantly my insurance would have been cheaper if I went with the older WRX and that is with 2 points on my license.

If you do get teh N/a get the power perfect, injen intake, headers and and exhaust. Then spend the rest of your money on suspension. I would get coilovers first.

(thread turned into more than just a question of exhaust. Funny)
