okay this is my first post... after trolling a little bit i have not came across anything to answer my question. WTF

i just purchased my 98 eclipse gs earlier this month and im already itching to get some performance under the hood.
ive got a cold air intake lined out already and i am definentaly considering headers.

my main concern at the moment though is exhaust.
i am not sure if i want to do a cat back or axel back exhaust. if i was wanting to get headers would that be considered full exhaust? (im pretty new at this so dont mind the noob questions, there are alot)

i have found a flowmaster axel back exhaust at a pretty good price but i cant find any sound clips or anything. i do not want the dreaded fart cannon.

dc sports has also caught my eye.

DC SPORTS CATBACK EXHAUST 95 96 97 98 99 ECLIPSE RS GS

its 436.00 thats pretty steep.

im looking for a quility exhaust with a deeper tone. i also want to save as much money as possible.

could someone explain the differences between full,cat back, and axel back exhaust.

im open to any suggestions so fire away :thumb:
 
I am somewhat new to this forum as well but I have dealt with other Mitsubishis and imports in general.
First off relating to automotive creations usually the more you spend and or are willing to spend the better off you will be. Of course if you can learn to weld and fabricate your own stuff then ## a couple steps ahead :)

Upgrading your entire exhaust system is usually the way to go... of course when you are dealing with a turbo setup the closer u get to the motor the more your vehicle will be able to breathe and the more power you will see out your hard work.

With an NA setup such as your it is still beneficial but there are varying thoughts on the subject. In my opinion I would say that it would be a good idea to go with replacing all of it. I would never spend the money on just getting an axleback/muffler exhaust as its more for looks and not really for performance.

Try to find a good HiFlow cat, Random Technology make a decent one, and a cat-back to go with it. Its always good to try to save as much weight while you are at it. something Carbon/Titanium is a good route.

If I missed something and u would like further help ill try my best...

Welcome. :)

I might be wrong here so feel free to correct me. Anyway, here goes:

Full exhaust = header (you have a header, not headers, since 420a is an inline-4 engine, not a V8) + catback, possibly cat replaced with a hi-flow unit or just test pipe.

Catback = Exhaust system from your cat converter to the back of the car (hence the name)

Axle back = just the last part of the exhaust changed, ie. the piece starting from the rear axle


Then to my advices.

First, quality and saving $$$ don't walk together unless it's about engine internals or other parts that move fast and undergo rapid acceleration and/or deceleration (because cheap POS piston rods can wreck your whole engine and become very expensive, for example). Usually you have to compromise, and the perfect spot to compromise in terms of money are parts that don't move (much). What I'm trying to say, a pipe is a pipe. A HKS or some other "as seen in F&F"-badge doesn't automatically make it better. It's gotta be of reasonable diameter and not to have leaks. Period. The tone and exhaust note is mainly created by the muffler.

If I were you I'd just go to eBay and buy some cheap set consisting of a header and catback, T304 as material is good (stainless exhaust is always better imo).They are cheap and will do the job. If you plan to go turbo and aim for bigger power in the future, buy 3" exhaust, but if you are going to stay NA or budget turbo with less than 10psi boost then 2.5" is easily enough and the best choice. Deleting the cat and using a test pipe will give you some ponies but it also causes rasp to the exhaust note, so I'd recommend a hi-flow cat. I have a Magnaflow universal model, bought it off eBay for $90ish and works great. It is also EPA certified.

If you grab the cheapest ones you should get a header+catback for around $200 shipped, throw in a hundred more and you'll have plenty of options. I have a set bought from seller "ilovetacotaco" (I know, LOL what a nick) and I like it. A bit noisy but that's how it should be imo, gets the grannies to move outta my way. :thumb:
If you wanna have a silent exhaust with better flow, ask a local muffler shop to do it custom made or just buy a used 2g GST catback, it'll fit right in place. (notice: GST not GSX.)


Cheers and good luck,

Olli

Next part is that you start running rich in the higher rpms so a SAFC II or other fuel management is needed. If you need more bang for your car consider an UDP, it's a popular and reasonably cheap mod too.
 
okay so i found this on ebay
Eclipse 95 96 97 98 99 Non Turbo Exhaust Header & CAT: eBay Motors (item 110588262712 end time Oct-19-10 09:45:16 PDT)

with this is would still need the cat back exhaust right? since that one only includes the header and cat? youll have to forgive my noobness haha i went from a 98 dodge dakota 5.2 to a 2.0 big jump

on the cold air intake, would it be okay to go for a ebay one as well and just replace the filter or keep it all together?

or would that and this 1995-1999 MITSUBISHI ECLIPSE 420A NT CATBACK EXHAUST 96: eBay Motors (item 330354075443 end time Oct-15-10 17:03:30 PDT)

make up the full exhaust?

To be exact that is not a cat, it's a test pipe so might cause some rasp in the sound but if it doesn't sound good you can always replace it with a hi-flow cat instead. So, imo this set looks ok. The test pipe flange is 2.25" and the catback has 2.5" so you gotta make a custom joint there but this is very common with these sets, can't escape that easily.

I have the AEM cold air intake and it gives good hp gains. On the other hand, CAI sets still consist only of a piece of pipe and a filter so any cheap eBay set should work if it locates the filter in a place where it can easily get fresh cold air. If the filter in the set seems to be crap you can always replace it with a K&N or similar "name brand" to be sure, as you said.

Meh, I've got mixed emotions on this, everyone says a pipe is a pipe, blah blah blah, I've got no money but want to go fast blah blah blah etc. So the first thing most people do is go to ebay and start looking around for cheap upgrades or knock offs of parts that have had countless hours of R and D go into them. We have already started to see the downfall of doing this, Unorthodox Racing is not producing our underdrive pulley anymore simply because the demands of the pulley are not high enough anymore. So yes you can still go to ebay for one but what happens if you need to call the company and ask them a question about it or have a quality control problem with it...most of the time your stuck with it. Now don't get me wrong, I don't think its bad to save a couple of bucks but its also hurting the community because NOBODY buys namebrand products anymore, its all ebay stuff. I had a Tsudo N1 exhaust on my car, from ebay, and I never had a problem with it. The fitment wasn't great and required some dremeling and what not to make it fit properly and sounded ok, and face it, your car is still N/A at the moment, its going to have a raspy sound to it at some point. But then I saved up some more dollars and purchased a Thermal R&D exhaust, love it. Sounds amazing, had no problems fitting it up at all. Sounds 10000000 times better than the Tsudo, but to each there own. Now for the intake, I'm surprised I don't see more talk about the AEM V2 intake, its not just a pipe, when I was NA I ran one and it seemed to be great, maybe it was just me but I liked it a LOT more than just a pipe with a K&N on the end of it. Take that for what its worth, its just my 2 cents. Yes sometimes you have to pinch pennies but then again sometimes the outcome is a lot nicer as well.
 
If you have a mig welder it would b cheaper to buy 2.5" pipe and get the pre fabed bends and make your own. I spent like 250 on all the pipe and I don't have a cat or a test pipe its just straight 2.5" pipe straight through. It takes more time but the money you save from having a shop do it makes it worth it and I love welding so its fun fun fun :) ! Good luck man

Not when ebay sells the exhaust for 150 shipped. Ebay....the destroyer of small businesses and good R & D departments....
 
ahhh so many mixed answers.
im wanting to keep my car n/a for a while because i have no clue about the maintenance of turbos and i am using it as my dd so i cant afford any mishaps.

if i was to go the ebay route i could get the exhaust, heads, and cat in about three or so weeks. (damn you minimum wage!)

it would take me couple of months to save up for the name brand stuff.

i have heard that brands are just money pits and the ebay stuff is the same, but i have also heard that the ebay stuff is not very high quality.

the tuner life style is so demanding haha.

here is what i will probably do.
1) get the headers and the cat back off of ebay.
2) i found a aem ram air intake for 133 i do believe and it has a waashable filter with a life time warrenty.
3) if i can find just the dc sports muffler ill jump on that and just weld it on and call it done.

so im going some quality and some cheapy parts.

im wanting to eventually completely build the engine but it will not be happening soon unfortunately.
there are no shops around the area i live (ada oklahoma) so i have no helping hands.
this is my advise super source and i thank everyone again for helping out.

if any one knows where a used higher quality exhaust is that i could pick up in the next couple of weeks please let me know.

also i was trying to get some pictures uploaded. but when i went to resize them and put them on it wouldnt let me for some reason. just sat at the loading screen forever. i would like to gt some pictures up of what im working with.

My advice would be against a short ram. It only sucks in warm air from the engine bay and hardly gives you any gains. Cold air intake is the way to go. AEM filters don't need to be washed or oiled, ever. If it is clogged just clean it up using compressed air. You could try to find a used AEM CAI for example from craigslist or ebay and get one reasonably cheap.

For example here is a very good deal, if I were you I'd catch this one:

AEM COLD AIR INTAKE 95-99 MITSUBISHI ECLIPSE - USED: eBay Motors (item 200506981719 end time Nov-08-10 12:58:29 PST)

Your exhaust plans seem good. Try that cheap header & catback and see how it sounds like, if you don't like it then go to a brand name muffler.

Good luck man!

That's certainly the theory behind CAI's, but in reality there isn't a significant difference in the measured intake air temperatures between CAI's and SRI's. Many times, especially in the summer, the air near the asphalt is just as hot as the air in the engine bay. Even in the winter, the volume of air moving through the intake is enough where it doesn't have much of a chance to be heated by stray engine heat anyway.

The "short ram" intake is the best design in my opinion. It's as short as possible; less restriction. Before I installed the turbocharger, I used the aluminum pipe section of an eBay intake together with a K&N filter.

OP, as for the exhaust, why not get the best of both worlds; cheap and name brand? Given the age of our cars, the economy, and several other factors, there's an unprecedented amount of used parts on the market today. You can find a good name brand exhaust for just as much, if not less, than a brand new eBay exhaust. Certain models, like the Apex'i N1, are more popular than others so there are plenty of them available. The same goes for the header.
 
dang seems like someone knows their dsm's! i will definitely look around for a used exhaust that is also name brand. probably do the same for a intake as well. thanks man!


ive been looking around for good deals on exhaust. could you possibly give me a link or two?

here is a pictcha
