buddy of mine has an 08 evo x gtr. he has the same intake uicp as i do. ultimate racing DP and same HFC. but stock on the rest of the exhaust. he actually took his ride to cobb plano and had their 3 port put in and a tune. hes putting down about 330 whp. i havnt actually taken mine down there yet but im running the stage 2 cobb Ap. one would assume im prob putting down about the same maybe a little bit less because i havnt had it pro tuned yet. i figured i would run what i had for a bit since i had to deploy over seas and there r some other things i plan on doing when i get back. ive actually been emailing back and forth with cobb plano on some build options as we speak. my advice with anything u do with your evo is to do it right the 1st time. if u dont u will spend more money down the road when it breaks. depending i guess on how long u plan on keeping the car. if u dont have the cast right now just wait a little bit till u do and get the stuff u want. name brands can be pricey but imo u get what u pay for. sucks having to wait i know. im an impatient person with most things lol.

 

It's just I don't have big clips of cash like I used to, economy has laid a smack down.

Personally I have no problem changing a few parts, just don't like the single outlet exhaust, to me it looks crappy.

I know the best gains is from the exhaust, but can't I change the cat & remove any of the restrictive parts, just dont like the thought of having a coffee can style muffler, I'm used to true dual exhaust, although that was a n/a motor.

at least if the stock muffler is on, Johnny law isnt going to care.

Cops by me just go after the loudest 4 bangers & they could see a srt8 with no mufflers & it's ok.

Plus half my neighbors just had babies, I live in a cul de sac.
Don't want the whole neighborhood hearing me come & go.

They all used to complain about my last car was loud.

 

Dealing with the neighborhood thing, they can't do a damn thing about it if you are leaving and arriving within the hours of the noise whatever you wanna call it. Find out what that time is, here I think it's 6-8 or 9.

 

Yeah! Forget about whether you SHOULD be doing it. Only think about whether it's legal. That's how to be a good neighbor in modern America. F, yeah!

 

Is the HFC & mid pipe enough, with a cai & ebc.
Or is it a fail without the catback.?

Or maybe a catback with HFC cai & ebc. ?

 

the only part of my exhaust thats AMS is the DP. the rest is all ETS and its dual exhuast. as for the noise, anything u put on after market is prob going to be louder than the stock especially if u mess with the CAT. but thats kinda what u want right? i try to be conscious of others around me and i myself dont like to draw to much attention but at the same time its a free country last time im checked and people dont like it then people can eat cake!

 

If you are worried about exhaust noise, just get a UICP, 3port and either a HFC or intake. I'm in a similar pickle, but unsure of the intake at this moment. Don't want my tune to push me to the limits of appropriate AFR since I don't plan on putting a wideband for a bit (also tight on cash). HFC and wideband are a future mod for me.

By the way, I have the ETS V2 Quiet, and it's a great exhaust. It is louder than stock though (obviously). Not too loud though. Just a lot more grunty. This is coming from someone who hates loud exhausts.

 

Not changing your exhaust is easily one of the biggest restrictions you can leave on the car. The best exhaust for a turbo can is no exhaust, and you are leaving press bent tubing with resonators and cats. Any significant mods added to the Evo will chock at the exhaust and add detonation. Get a 3.0 turbo back pronto.

 

I can't figure out how to post so I'm trying this. I'm wondering if anyone can give me a an idea of whp and torque wit these mods.
Turbo back ams exhaust
Ets test pipe
Perrin 3 port
Synapps bov
Ams short ram intake
Kelford cam shafts s2
Fuel pump
1000cc injectors
Ams fmic
Ams licp
Tomei uicp
I think that's it. I had everything but the cams front mount fuel pump and injectors. I put down 298whp on a dyno dynamics wondering what I'm goin to jump up to after the new mods. If someone has any idea your thoughts would be appreciated.

 

Yea, looks like the ets v2 quiet is the way to go.
Again should I do the turbo back or cat back ?
I am getting mixed opinions on the turbo back vs replacing the cat & cat back.

 

I am doing similar mods. I ordered an AMS intakeand UICP. I am taking the car to Cobb SOCAL to get a turbo back exhaust and AP. I am just going to run one of their flashes for the next month or so then I am going back to get an intercooler, 3 port boost controller, and tune.

Do you think the AMS DP is really worth the extra money on a stock turbo? It cost a couple hundred more for the part and a couple hundred more in labor to put on. In all it cost almost a $500 more.

 

Is it, that's not good.
That's why I need input, I don't want a downpipe if it donf work.?"

 

My first question would be how much is ur budget? Then we can go on from that.

U want more power, then let the car breathe. The biggest bottle neck is the catalytic converter. Next would be ur intake filter.

Getting a 3port for a mostly stock car wouldn't help anything. And a new BOV wouldn't do much since stock BOV is good until 25psi (or 26, can't remember). If u like the "psssh" sound, get an open filter and u will hear it...albeit faintly, but u still hear it.

Downpipe is a PITA to install. If ur not mechanically inclined or just too lazy to install it, getting someone else to install it will be money deducted from ur budget.

Stock UICP and LICP r good enough if ur not gonna push ur boost higher (stock boost is at 22psi). Reason most people change out the UICP and LICP would be for heat expansion. Stock UICP and LICP rubber expands when hot, just like anything even metal. Hard pipes diminishes the expansion caused by heat and higher boost. It also diminishes the erratic boost pressure caused by expansion. Plus, it looks a lot better than stock, the UICP at least... LICP is hidden. Some people changes out the UICP mostly for looks.

320-350awhp can be had with bolt on. I'm sitting on 350/350 right now on stock turbo/stock internals. What I have is intake, UICP, FMIC, LICP, turbo back exhaust. I let the car breathe better and I tuned the car myself (with lots of help from people here on the forums).

I would say u do need UICP and LICP just to eliminate the erratic boost fluctuations caused by heat expansion, and a better intercooler than stock. Unfortunately, if ur going to get all this at one time, it might break ur budget. That's why my first question was what is ur budget. To me, a small budget would be $1k, but it really differs from one person to another.

Real power adders would be FMIC, intake and turbo back exhaust (eliminating the stock cat converter), everything else r support mods. And of course, tune.

Set and tell us ur budget, and we can go from there.

 

It's closer to 2 grand.
already tuned, so want to upgrade to reach power levels I'm looking for.
This looks like my best bet.
Uicp/LIcp
3 port ebc I'd be happy running 25-26lbs.
HFC & cat back.
Intake
Then retune, since already tuned.

 

A few things first. What I get from talking with other people is you don't need an aftermarket downpipe until you are going to a different turbo. Yes, you will see a little gain, but those things are not cheap and a pain to install. And then if you don't want to install it that will only increase the cost, and I heard they aren't cheap to install.

As for the blow off valve, like others have said, the stock one will do just fine unless you're just looking for the sound. Since you're on a budget I would skip it.

When you say cold air intake, do you mean the AMS one, or the AEM one? The AEM one would be fine, but you can't do the AMS one since our SST cooler is down where that intake goes.

The LICP is also a waste of money. I don't believe it adds any horsepower, so you'd only want to do it if you want to run the Tial blow off valve or something like that, but that set up runs around $700.

Basically, you should look for a CBE, HFC, intake, UICP, 3-port, and a tune.

$900 for CBE
$250 for UICP
$250 for HFC
$100 for 3-port (I don't know exact prices for this)
$350 for intake
$500 for tune

That puts you at $2350, but you can go shop used and save some $$.

This is the best thing to do on a budget from what I have heard over the past couple of years.
