another apexi n1 question *sorry*

[madcheba]

ive been looking for an exhaust for my car. and i know there are many out there. but many eclipse pages i see use the the apexi n1. i found one too for a good price ($469.00) at

http://www.mvpmotorsports.com/Templates/frmTemplateH.asp?SubFolderID=113&SearchYN=N

but as of course im sure evreyone know it is only a "partial 3in exhaust" ive read some of the forums reviews on why some people didnt like it but then why do so many people have it. they always say they love it and its great. i mean why would apexi use their design if it wasnt goin to help performance. is there any "major" performance differ between an n1 and a custom 3in. thanks.

-The Apexi N1 is a 3" cat-back system that bolt up to the stock down pipe, the only way to accomplish this is to use an adaptor, I think it's a good product, I just down like the 4" tip on the muffler, some "anti-rice" people might stuff thing it there.
-Either "Turbo" or "Sport Compact" did a comparation on some of the most popular cat-back systems a few months back, they rate hp gain, noise variation compare to the OEM set-up, but the test was done on a Celica.

I'm having a little bit of a problem translating the post before mine so I figure you will too.
The N1 does not bolt up to the downpipe. It bolts up to the cat with the use of an adapter. I actually have the N1 so I can tell you about the exhaust. The N1 is a very nice piece(quality and sound). The only problem that I have with the exhaust is that it's not actually a true 3in exhaust. Inside the can itself, it's actually bottlenecked down to 2.5in. Other than that, it's a great exhaust. The exahaust really looks nice on the car also. I have some pic.s of it in the gallery.

 

[larryd]

really, i never knew the inside of the can was 2.5". I know the downpipe is 2.5" to a 3" right before the cat but I thought the exhaust pipe itself was a true 3"

 

[VBGSX]

Hey Larryd........yeah, I posted the pic.s of it a while back. Right before it exits the can into the tip. Let me see if I can find the pic.s again. The rest of the piping is 3in.
Found it

hmm, that kinda defeats the purpose huh.. i wonder how much of an issue that is

 

[nellystyle]

not to jump on your thread here but i have a question...

would it be cheaper ( but equally as good more importnatly) to just buy the muffler apex n1 and have an exhaust shop custom bend you piping cat back? opposed to buying the "apex cat back system" which you're paying for the name...seems to me that piping would be piping no? thanks because i'm looking into the n1 right now

agreed.

you can even buy 3" inlet/4" outlet N1 style canisters on ebay with silencers (to make em nice n legal so the cops stop pullin u over on ur local hangout) for $60-70. Then piping costs what...maybe 150 including welding? for ~240 u can have a 3" downpipe back system.

it would be cheaper.
and yes, piping is piping but u also have to consider the quality of it.

 

[VBGSX]

Megaman is right, plus.....and consider the quality of the N1 style can. I've heard some copy cat cans sound very raspy and rattle
Here's the real deal. This is the one for the GSX. The only difference between the GSX and the GS-T's is that the GS-T piping goes over the rear axles and the GSX's goes straight back under the axles.

I love my exhaust

 

[GreenDragon_Gst]

yeah... the N1 is phat... got it on mine, too... I got the downpipe aswell
(no cat... tee hee ) what's funny is that they screwed up on my order and gave me the gt downpipe(stainless steel) when I ordered the n1 downpipe. The one question I have is the for some odd reason when it's cold outside(like in the morning or at night) after my car warms up, when the RPMs go down to about 1200 there's this loud chatter like it's tapping the rear member or something. I tried to re-fit everything, but it still persists. Does n e 1 know if there is like an exhaust wrap or something I could put between the exhaust and the member?

 

[TSi92]

So in theory my $90 ultraflo flows better than the $250 N1? I saw mine and it's 3" inside.

 

[Devicex]

If you take the numbers off of RRE's site on the N1, 70mm expanding to 85mm, it calculates to about 2.75 inch expanding to 3.34 inches in the rear.

 

[98cLipsE]

i got the n1 on my 420, i love it

 

[Slappster]

How much is the shipping of the N1 exhaust system from machv? I tried to see by adding to cart and thus forth but I have no credit card. Hopefully its not more than $30.

 

[drewstealth94]

Well i have the complete n1 system. The dp and the catback. I like it a lot. I hope that the canister being only 2.5 inches doesn't hurt performance to much. I was going to just by the muffler and have an exaust shop do custom 3 inch manderal bent pipeing but only 1 person in my whole town did 3 inch manderal. And it was only gonna be $30 cheaper so i went with the n1 system.
To GreenDragon GST my exaust system was hitting under my car where my cat was. So i had to have a muffler shop re-weld the 2 hangers so it wouldn't be touching. Now it doesn't make any noise. It only cost me $35 for them to do it. It only took 30 min also. I have a 1g and awd so my pipeing is different then yours but maybe you might have to do the same thing.

I don't know about the cat back part of an N1 system but I just bought the down pipe and it is not a true 3" pipe. From the 02 housing to the flex section it is 2.5" and from the flex section back it is larger but not a full 3" inside diameter. It has an outside 3" diameter.

That being said I still love the pipe and it did make a noticable gain in power. As for a cat back system I still love my Thermal It is a full 3" inside diameter all the way through, muffler and all. It does, however, take some modification in order to bolt to the N1 downpipe. I had to cut off about 3 5/8" from the Thermal pipe mostly what was the flare and flange to fit the stock cat. From there I had to make a flange to bolt to the N1 downpipe. Took about 4 hours including fabrication of a flange and an hour die grinding the hole big enought to fit over the Thermal Exhaust. (Only had a 2 3/4" hole saw)

I have a GST and my N-1 goes uner the rear axle????? It won't fit any other way.

wait, the GS-T piping goes over the axle? I could only get mine to fit under???I cursed at it...spit on it...and it still coudn't go over.

 

[99blkgst]

Same with mine. I was like "wtf"??? Oh well, it looks better going under the xle anyways. But there is no way it could go over the rear axle.

 

[VBGSX]

I guess I will have to stand corrected. I was told by a GS-T owner that it went over the axle and I thought I also read it on here somewhere. Sorry for the misinformation. I will only speak of the GSX for now on....hehehe

 

[99blkgst]

No bashing man.. Just stating from personal experience

 

[kamakazy59]

couldnt you just stick a dremel in the exuast and cut out the 2.5 in. piping just a thought.

 

[mclaren55]

Its fine, I don't like how it isn't stainless steel, but other then that its fine. That 2.5" can't be that much of a bottle neck, it supported the power I made, which brings up an interesting situation, wonder how much power I can make with a true 3" exhaust. hahaha.

 

[na90dsm]

ok, i dont mean to hop in but i got a ques.im planning on swappin over to the turbo motor soon,this means i have to swap exhaust to go with the turbo setup.can i swap to this exhaust or will i run into problems.
