Just curious, I'm fairly new to the car world, but what would you suggest as an upgrade for my factory exhaust setup... As far as I know it's all stock...
Thanks in advance for all the help!

Stock Exhaust system...
- Thread starter fiyota
- Start date
This has many factors involved in it, as its a very open ended question.
What is your budget?
-If you have a few hundred to drop, you could get Headers, and a full exhaust system.
-If not, you could hollow out you cats (test pipe) and put a aftermarket muffler.
-Or jsut a cat-back exhaust sytem.
Whats your power range?
Are you turbo'ing later? If so i would recommend a 3 inch cat back and test pipe (what i have on my N/A). It performs very well.
Give us alittle more information and you can get some help!

Thanks for the quick reply!
Really, I kinda want to know what the stock setup is, how big is it, could I just put a high flow muffler on it for now, or is the stock exhaust too small. I dont have a whole lot of money right now, so cheap as possible, not going to do headers and I probably wont be turbo'ing it anytime in the near future.
My stock muffler has a bit of a rattle and I was thinking about getting rid of my cat and doing just a muffler, but that depends on how big the stock pipe is

Ok, what i would do if i were you.
Purchase a test pipe (30-50 bucks)
And buy a magna flow muffler.
Any muffler will fit, may require some modification, but not much at all. And if you really can't do it, then a exhaust shop will put in on for cheap.
This combo will free up your exhaust a lot and give you a little boost in performance!

that test pipe says it's a 3" diam. will it fit my stock exhaust? How big is the stock exhaust?
Thanks a lot!
Thanks a lot!
Im actually not sure at all. I have a test pipe on my n/a and it bolted right up, and i have a after market exhaust from there back. I would see no reason as to why it wouldn't bolt up, and ive heard of people putting some gaskets to make it fit.
Or just hollow out your cats! Its free and easy.
And have you done anything to your intake system? The more air you bring in, the more you can let out.

I'm going to be getting a new air filter, and making a metal heat shield to keep the engine heat out, then using a metal pipe instead of the plastic resonator that's currently on there, and attatch that to the factory elbow going into the intake manifold.
I would prefer to not have to swap out my full exhaust, but I do need a new muffler, and would like to either gut out my cat or get a test pipe, I just wanna know how big the stock exhaust piping is.
Thanks for all the help so far btw

2.25 inches IIRC, maybe 2 inches.
Bottom line is its too small.
Heres my non-turbo intake/exhaust set up!
Just disregard everything else in that pic. Dirty and rusty! Much better/polished now!

Whats that line running to the polished pipe for your intake?
I just went outside to have a better look at my exhaust, it's raining.... anyways, i can see the cat, right where it comes down from the engine, then there is some piping, then about halfway down the car it looks like a smaller muffler, then it looks like brand new piping to the muffler, wich has a bit of rust on the weld that's facing the back of the car...
I'm curious as to what that smaller muffler is... I'll take some pics in a few minutes.

LOL- that small muffler is the "cat".
Im not sure what you originaly thought was a cat, but that may be the headers...
And that line from my intake is a vacume line.

hmm, odd, didnt know that cats looked like that, all that I have seen are kinda wierd shaped, not like a muffler... ah well haha, like I said I'm new at all this. anywyas, here are some pictures of everything since i've already gone out in the rain to take them haha...

haha ya, that's what I thought, some kind of resonator or some type of silencer... it looks newer than the rest of the setup, and the pipe coming off of it looks brand new, going into the old rusty muffler....
Stock exhaust for these cars should be:
cat -> muffler -> resonator
What people commonly call a "muffler" is actually known as a resonator. Most systems that have been "upgraded" lose the muffler and replace with a straight pipe, then to the aftermarket resonator. Since there's no longer a muffler after this, the resonator becomes the "muffler" now. What results is a drony exhaust note that sounds good to some and terrible to others.
Take a look at IJ's buildup pics to see how an aftermarket (and fully custom) exhaust can address noise and performance both! Sorry for the shameless plug Ian!
Bottom line, if you remove the center muffler, it'll be noisy. Whether or not you gain any extra noticeable power depends on quite a few other factors. Namely, how restrictive the rest of the system is and whether you want noticeable low RPM response or more top end power. As a rule, NA systems need a bit of backpressure for low end response/torque and if you eliminate that, you'll likely lose a bit of low end response but gain a bit more on the high rpm side.

so if I were to put a test pipe in or gut the cat, take that muffler out, and put a new resonator/muffler such as a Magnaflow where the old rusty resonator is, I would probably be losing some low end power, but possibly gain a little high end?
Instead of hacking apart my old system, would it be better to get a full catback setup... how wide of exhaust pipe can I connect to my manifold?

To your first paragraph, the answer is usually "yes." How's that for vague? Seriously though, that's pretty much the case - less responsive low end (but possibly not so much so that you'd think, "man the car's sluggish") and a bit more power up over 5k rpms. Bear in mind though that this is a guess and depending on how your motor is running, things could be really different in practice.
I would imagine, based on what you already have, that the only thing you'll gain by attaching a catback system is likely to be a change in sound characteristics. Without changing the rest, you'll probably not get any gains in power. The good news is you're not likely to lose any either - unless the internal diameters of the catback system where smaller, that is!

Scratch that! I was thinking you were talking center muffler back, not cat back. You would propbably pick up some increased performance if you did what you're talking about. Sorry if that was a bit confusing...
haha no worries, I think I got it, thanks mickyg for the help! So I'll try to come up with a plan for my exhaust... either scrap my muffler and old resonator and put a straight pipe from the cat back to an aftermarket resonator, but keep the same diameter pipe that is coming off the cat.
Or I could start fresh from the intake manifold and go something like a 2.5" or 3" exhaust all the way back with a test pipe.... hmmm

depends on your smog laws. if your required to have a cat,just put in new piping from there,and end up going through a Magnaflow muffler. i had 2 cats on my old n/a,and the piping was 2 3/4 inch mandrel bent. it had a nice mello note and not too loud.
i would not even bother with a resonator,just sraight to a muffler.

fotosoup: Both ideas sound like they'll work. If it were me and I was on a budget (wait, that IS me!), I'd probably just replace the resonator (the last one on the pipe, to avoid naming confusion). Especially since it's actually got problems with rattling.
If money were less of an issue, I'd go with a more elaborate setup and just get higher flowing components all around. You get a quiet exhaust but a with a deeper tone than what you have, plus you just might pick up some performance! Bear in mind though that once you start making things bigger, other things will become bottlenecks - quite literally! I don't know at which point the stock exhaust manifold starts to choke but someone with a bit more experience could probably tell you. Also note, you accomplish nothing by making your exhaust bigger (except changing the sound) if your intake system isn't flowing enough. It's a vicious cycle!
