which would give better gains for the cobalt ss.

well you are only going to get true dual exhaust with a v-6,v-8,v-10 something with two sets of headers or something with split headers...what the cobalt would have would be a single pipe from the header back to the rearend then you could have it split to have two exhaust tips or a single, with this I don't believe there is a significant gain over the single outlet or dual outlet in the rear.
So now your dilemma would be what size of pipe to get, 2.5" or 3".
If you plan on having some high HP go with the 3", even if you don't really need it right away it will open up the doors for more power down the road with the more mods you add. Modern Performance is testing a 3" exhaust now go check out their section in the vendors area for more info.

I agree. Probably no real gain to be had until you start making very substantial power. If you were making much more power, had a large primary from the header, and a hi-flow or no cat, then maybe you could make a performance case for a dual setup. But until then, it's just cosmetics...

There is no gain with a dual exhaust (in my opinion) not with these cars, heck I don't even know why they put that on my car, although it does look nice. But if you go with dual, you're ricing out your ride, unless it comes stock. Just my .02

How is 2 tailpipes rice?
I swear that term gets thrown around way too much and by people that have no idea about what is and isn't.
Why do they put it on he asks....a specific reason other than looks, I'm not sure.
Compare performance vehicles from the last 40-50 years or so....name performance vehicles that had two tailpipes to those with only one, it just looks better.
Camaro's and T/A's fell into this as well with having a single exhaust pipe and splitting at the rear into dual (outlets).
Dual exhaust is two exhaust pipes seperated from each other from the engine to the rear....except for the occasional 'X' or 'H' pipe thrown in. One exhaust pipe on one header. One muffler for each pipe.
SRT/Cobalt/most other 4cyl are single exhaust with dual exhaust 'tips' at the rear of the car.



Something that may be considered rice would be those with a new rear bodykit with spots for two exhaust tips but the vehicle only has one.

Well i will most likely get the dual's because i like the overall look of it and even though there is no gain there will be a different sound and tone. :)

I agree.. 2 pipes look better then one :) unless they have 6" tips or something!!
then we are talkn' rice...

No they are not that big. they are like 3 or 3 1/2 inches i think.

the tips on those are probably ...3"-4" the mufflers are most likely about 5"-6". Myself, I just don't like to be able to see the muffler(s).


Edit:
Just so you have a better idea of idea of what Iw as talking about with single exhaust, dual tips (for those that may not know) here are some pics of the stock srt exhaust.

Hell yeah! STRAIGHT PIPES from the factory!!! Wish we coulda pulled that off!

Edit: on this note, there's a guy around here that has an SRT-4, ok first off he's a dumba$$, He has this powerful four cyl and can only hit a 10.3 in the 1/8. Couldnt figure out why. A friend of mine got to drive his car and pushed it to almost redline, and the SRT guy got pissed cuz he revved it so high. Thats why he's slow as shit, he launches like he's racin his lil sister on her ten speed and wont come within 500 of the redline. Anywho back to my point, I asked him if he knew that he had a straight pipe from the factory and he GOT DOWN AND LOOKED and said "No, they arent straight." I was like nevermind man... He doesnt even know what he's drivin!!!!

I have found this with quite a lot of people....sigh....
if you say straight pipe, people actually think the pipes are straight (not curved)
lol, and for those that thought this before.
Slang terms , straight pipe(s) mean you have no mufflers, just exhaust pipes. It doesn't mean that the exhaust pipes are actually straight from the front to the rear with no bends.
SRT-4 has no mufflers just 2 resonators, if you look in the 3rd pic I posted above you can see them.

Anything that doesn't give performance over stock is consider as ricer in my book. Different people have different opinion on what ricer is, but this is my .02. Yes, it does look nice, but if there is no performance gain, other then looks, then in my book is consider as rice. I'm all go, not show. Now I understand that other's might not agree with me, but hey, everyone is entitle to their own opinion. This subject has been beaten down to death on the SRT forum as well, on why the SRT got dual tips, when all we really need is one. But if you guys want to get dual tips, be my guest, just make sure that when it's cold, and you're lined up at the track, that people don't only see one tip with steam coming out while the other tip is just sitting there. I was cracking up when I saw that on a Honda.......

thts wht i was wondering if the second tip would just be pure cosmetic and not have any steam coming out of it while the other did in the cold? would this be the case for the cobalt and the modern performance exhaust?

Probably not, I'm pretty sure that if Modern makes a dual tip exhaust for your car, that it would probably be a functional dual tip exhaust. Meaning, steam should be coming out of both tips. Modern usually do a good job in making their parts, so I wouldn't worry about it.

Daul Exhaust is as unecessary for a 4 cylinder as a $2,000 body kit, giant aluminum wing or any other Rice addition would be. All it does is add weight and cost for a worthless modification. I have single exhaust on my car and I have 485 hp and 540 pounds of torque at the rear wheels.

On the other hand a single exhaust dual tip muffler isn't too bad.

Yeahm but I am glad I got rid of the stock anyway...the tips were jsut too smal for the cutouts in the bumper, the 4" tips I have now fill out the holes and looks a lot better. Along with better flow and a better exhaust note to boot.
That exhaust takes about 30 minutes to change out, old out new in and driving. That is knucking futs

You have more cubic inches in your exhaust tips then you do in your motor! :D

hooray for me..so my exhaust tips are more than 148 cubic inches?
I would have never known that if you wouldn't have taken your time to figure it out for me. You do add something to the site. Thanks. :D

So youre the kinda guy that only cares about speed in his street car and not looks then I take it? Even though its driven on the street more than it is the track and people care more about how it looks than how fast it is. I guess if I bought better looking exhaust tips for my GTP even though they wont make it faster is rice too, huh?
I dont get these people who claim "all go and now show". Whatever happened to wanting to own a nice looking car that has function AND form in one package? Now it seems like its a burden if you need to buy something to make your car look nice. So sad :( :rolleyes:

Defining 'rice' is like defining 'life'. In all the years of scientific research, there's still no soild definition of what indicates 'life'. Same thing here, I can't tell you what rice is... but when you, or I, see it, we know it's rice....

Want to know what stupid is? Is when I leave someone who spent 5 G's on body kids and looks from the line when trying to race me. Now that would look stupid. Why try to make your car look fast, and then get smoked? Now don't get me wrong, I have nothing against peeps who can make their car look nice, and be fast. As for your comment about people caring more about how it looks compared to how fast it is. When you go to the Weekend tracks, who do you think peep's care to look for? A fast car, or a nice looking car that only comes out to park and looking good? As most peeps that comes out to the weekend tracks, are out for action, not attraction. Same thing with the legal track, do you really think that peeps go to the track to look at a nice car? How long can you admire and look at a nice looking car?? There is a reason why they have events for "Car Shows", and "Racing Events". I'm the kind of guy that would rather see a car in action then sitting on a floor. That's just my .02. As for rice, it was my opinion, as you're entitle to yours. But calling other stupid, because we don't share the same opinions is just plain childish.

You never said anything about making a car look fast and then pretending it is. I find that stupid as well. You just said "Anything that doesn't give performance over stock is consider as ricer in my book" and "Yes, it does look nice, but if there is no performance gain, other then looks, then in my book is consider as rice."
That is pretty stupid thinking. But the statement "Why try to make your car look fast, and then get smoked?" I can totally agree with, as well as racing someone who thinks theyre fast because their car might look the part from $5k of garbage body work. But chances are if someone is doing a dual exhaust setup on a Cobalt, theyre not trying to "look fast", theyre probably just trying to make the rear of the car look better and more aesthetically balanced. Theres nothing wrong with making a car look better and more balanced, is there?

And when I go to the track, I like to see a nice looking car thats also fast, and I know a ton of others that feel the same way. Speed isnt EVERYTHING. If it was, you wouldnt see shiny paint jobs on regular joe budget race cars would you? Probably not, because they have nothing to do with speed and take away funds from speed parts.
When I was talking about nice looking cars though, I was mainly talking about street cars that are driven on the track 98% of the time and on the track the other 2% where looks arent as important. For example: A friend of mine has a 90 Civic hatchback that runs low 14's with a turbocharged DX 1.6L SOHC motor. Yeah its quick, but its painted flat fuggin black! Its ugly as sin, but he doesnt care cause its fast. IMO, thats stupid because its a street car, and I know that whatever Im driving on the street, I want to atleast look decent. I'd be embarassed to drive around in that car, no matter how fast it is. Because as I said, speed IS NOT everything. If you think it is, youre R-I-C-E !!!

Well, you're about the first person that I've come across that would consider speed as rice. As a matter of fact, you're actually backwards on that. Where do you think people got the meaning of Rice from? The fact that you have a riced out car, and is weak as hell, is rice in my book as well. But for some reason, you tend to think that having a fast car is consider "Rice". I guess you're entitle to your thinking? As for a Cobalt having dual tips, I have nothing against that, all I said was that just make sure that if you do go with dual tips, just make sure that you don't have steam coming out of one tip while the other just sits there? Another rice situation. But I don't mind you calling me rice, as it's those that underestimate me for rice, is why most get left behind from the starting line. Thanks to my wing.

Is what you said, now that you're called on it, you feel the need to add more words to justify your own statement? Now we're talking about "Our" hobby? Not once have I mention any thing about who's hobby? I stated in my statement that it was my opinion. If you feel the need to add an extra tip to your car for looks, over performance, then yes, to some that would be consider as rice. Just because you're offended because of that statement, never have I said anything about anybody's hobbies. As we're getting off subject here, and I don't have time like you to argue the facts on what is rice or not. Like I've said, I don't really have nothing against rice, if it's your stlye then more power to you. If someone wanted to add an extra tip on a Cobalt, then more power to them. Don't hate on me just because my car came with an extra tip. Had my car came with one tip, you can be assure that one tip for me will be good enough.

Ok for the record, are we talking about just a tip here? Or are we talking about another piece of exhaust added to the car that has a function? Cause yeah a fake tip would be downright stupid and I would disagree with doing so as much as the next person.

You SRT4 guys amuse me more than the Mustang guys do.

Me personally....I would say if you are going to change it at all, go ahead and get the 3" and be done with it. It will give you the most gains and will open the door for more HP and TRQ down the road with the more mods you do.

Same here, If I ahve a muffler I would rather it be hidden and not seen at all if possible. Just the tips out the back, sometimes not even any tips. My old 5.0 moosetang, 3" dumps right out the back of the mufflers, no tailpipes.
