A'PEXi N1 Exhaust

[SPYD3R]

I was thinking about getting this exhaust becuase I like how it has the silencer b/c i am not a huge fan of loud exhuasts... but anyways. I found this kit on extremepsi that comes with a A'PEXi downpipe but it eliminates the cat, and I need the cat on so that it is still legal.

Would the stock dp and cat work well with the cat back of the N1 exhaust? or should I go ahead and find a kit or dp that doesnt elim the cat. Im not planning on doing heavy mods. All I am doing is changing the exhaust, fmic, and new intake, and maybe a new turbo.

Thanks

If you plan on doing a bigger turbo you should definately get a full turboback to let the turbo breath better, i have a VRS racing 2.5 inch turbo back with a magnaflow muffler. you can get them with a high flow cat or test pipe for like $600

You might want to do some research before buying parts. A FMIC on a stock t25 will slow the spool. If you want a good catback, Id go with magnaflo. The DSMers who I have talked to who have one are pretty pleased. An intake on your car isnt really gonna give you that much power...so Id just go with a K&N filter. You might want to invest in some fuel mods and some guages.

ok lets say that the turbo will be a future upgrade that I might put in at the end of the year...

The Apex-i cat back works great with the stock downpipe and cat. Then if you want to go from there, www.roadraceengineering.com sells downpipe with or without cat for the apex-i exhaust.

Get a K&N fipk or whatever its called

That is actually a great idea. so here, ill get a good catback, ill put the K&N FIPK kit, get some boost/vac gauges. I dont think that fuel mods will help me right now. cause I dont plan on doing any heavy modding. And the only reason I am getting an exhaust is because the shell I am buying doesnt have one, and I cant find anyone that will sell and ship the stock gsx exhaust. I the kind of person that likes the drive the car stock... but make it look real clean(new rims, tint, leather interior), like keep original look, but still lay the smackdown on hondas in the area...

 

[4BangR-x]

well you should be able to do that just fine with stock

I've actually beein doing some research, and alot of people say that this is a very nice exhaust system. And I will probably end up getting it if I can't get ahold of a stock 2G GSX exhaust.

Fuel is essential. The more fuel you get, the more power you make (assuming some tuning is done). Really even light modding should include fuel IMO. Here are the first things Id do:

Boost guage, Wideband O2, EGT guage
New BOV with full recirc
magnaflo catback and K&N filter
AFPR and Walboro 255lph
720 cc injectors with dsmlink
Datalogger
FMIC and Big 16G.

EDIT: dont bother with the stock, just a waste of money.

Either the Apex'i or i'd go with a HKS hi-power if i was you, i used to have one and it was great. I might actually go back to my old 3" exhaust set-up it was a Apex'i GT downpipe no cat to HKS hi-power, sounded awsome

x2 wish i woulda have it done that way...listenn!

by the way none of these exhuasts are loud and annoying. They are deep and have good tone. turbos do a good job of muffling a car

Well that eases things a little.

Okay sounds good what you are saying. But I dont think I have ever understood this: What is wideband, and why an O2 sensor? Also, since I am a newbie explain a little of what a AFPR (something fuel pressure reg.). And aslo full recirc means to not vent into atmos. and just vent right back into intake?

 

[crazykid]

Hmm, I believe you can get the Full Apexi N1 exhaust 2 different ways, The most common is the Turbo back version.. (downpipe to exhaust). But I believe there is another version, that is Downpipe to a testpipe or high-flow cat, then exhaust. Im positive there is a version where there is a section you can swap out for either a high-flow cat or straight 3in test pipe. Ill look around a see what I can find for you.

Ok, check out http://www.roadraceengineering.com/eclexhaust.htm Looks like Apexi only makes 1 version, but RRE makes a custom downpipe that you can use a testpipe or highflow cat that will bolt directly to a variety of exhaust systems (including Apexi).

On a further note, this 'Espelier 80mm SS Exhaust' looks rather promissing. Quoted from RRE "This system will outflow the old outdated and restricted Apex'i N-1". Anyone use it?

I have an apex'i n1, I can hear my turbo ''whistling'' at idle, Like an srt 4 I guess you would say. Its funny because it's so audible. My friend has the same one, But his sounds different, I guess his sounds like most other exhausts at idle.. I'm not sure why mine sounds so crazy.

Anyways, Hope you never have any problems if you shell out the cash for an apex'i system. I bought mine and a week later a hanger snapped off, I touched another one and it fell off and the welds broke and were leaking. Yes, Less then 2 weeks of use. I tried to get a replacement on only the back half/muffler but they ask you 1,000 questions and it was alot less stressful for me to just weld two little patches where the hangers were, Being they were not in use anyways as I have cut the stock hatch area out of the car.

So what is the deal with the Apex'i being all like angled at the exit?

A wideband O2 sensor is a sensor that goes before the cat that tells the computer how much oxygen is present in the exhaust. You use it to determine if you have too much/too little fuel for tuning.

AFPR - Adjustable Fuel Pressure Regulator. Used to control pressure in the fuel rail.

Full recirculation means to vent inside the intake or onto the filter. Im not a fan at all of the BOV sound...so I favor full recirc.

It is angled so there is less of a bend in the piping right before the muffler. This is supposed to help flow but in reality on a mild car it would make no difference.

Its also a look thing and all N1 style exhausts will have it. N1 is a type of race so you will se many different exhaust brands using it in their naming.

I like the sound of a BOV to an extent. I dont like it loud a squeekish like. But a simple whoosh is kinda cool.

 

[VicBoost]

I have a magnaflow exhaust system. It doesn't sound to bad, but this apexi n1 looks very interesting and I might grab it. Do any of you guys know how much it cost and where the best place to get one.

 

[DGajre777]

The Greddy RS makes a simple woosh (air) sound. Check the tech guide (parts feedback/review section), I have a review about the Apexi N1.

 

[SPYD3R]

I found one on www.dsmparts.com and on www.extremepsi.com (which is cheaper and has a kit too) and I think the cheapest for the catback was the roadraceengineering.com.
