Hello Guys/Girls. I have two questions about exhaust on the 07 cobalt ls. here it goes, 1.) Will it hurt my car to run straight pipe for a while??? Because it sounds amazing without the resonator. 2.) How does the MEGAN catback exhaust system for the 07 ls sound on the cobalt???

help is greatly appriciated thanks
mike

 

No and good...

Define straight pipe. You didnt mention muffler or cat.

 

haha sorry im talkin straight pipe like no muffler or resonator from the cat back

 

I have the pacesetter on my 07 and when i removed my exhaust i never had a resonator :S but unless your running turbo a stright pipe is not the way to go.

 

Thats gona be frkn' loud, don't be suprised if you get a ticket for exhaust that too loud. And if you do any highway driving, it will get very annoying...

 

not to mention the fact you will probably have a loss in low and midrange power running the straight pipe.

 

well i have been running straight pipe for about 2 months now and its actually now that bad and i was saving up for a megan exhaust and wanted to know how it sounded??

 

Here is a sound clip

hey i tired to pm you speedjunkie but you havent enabled pms.

heres what i was gonna send

its realy nice like no lie. its nice and deep not raspy at all. and on the down shifts and what not it gurgles and pops sound so nice. but its also not too loud if you have the stock header/downpipe. if your on the edge of buying one DO IT best 300 ish ive ever spent.

ill try to see if i can get a sound clip of the exhaust up.

btw nice car

 

thanks ilovecars, i just heard a sound clip of one on a ss/sc and sounded AMAZING as hell i think i will sell my 240sx that i cant seem to get running right and buy some exhaust im excited as **** if anyone wants to buy a 1989 240sx s13 hatch let me know or PM me thanks

if you can ilovecars, throw up a sound clip i am excited to hear what it sounds like

 

AHHHH give me give me give me!! i want a rwd so baddddd

and np next time i get a chance ill record it.

 

ok well i bought it like a month ago and worked on it everydayand it had a bad MAF and replaced that and it has not been run in like 4 months and am not sure whats involed in getting it to run right, the battery is bad, when it starts it will run for a minute but smokes like no other but wont run for any longer then a minute then shuts down but when it does it runs smooth as i dont know what. i checked for water in the oil like a blown headgasket but no water. broken water line i have to take the intake mani. off to get to the blown line. if i fix that and it willk hold antifreeze or unless you want to do it its up to you. but it sounds like the water pump seal or just a bad line for the coolant spilling everywhere but it needs a new battery and tire, it has the sohc KA24E motor. i bought it for 500 not knowing what to do but i dont really have time for it sadly i really want a drift 240 but i dont have the time or money to do it since i had to go back to school for my senior year

 

hmm you bought it for 500 so youll sell it for 300? !!!

 

you should definitly enable pms dude

 

ok sounds good haha were are you and how do i unlock PM's???

ok how do i unlock them???

 

user cp. and then edit options and under messaging say enable private message. click the little box

 

I love the way the megan sounds.

Is it 2.5 or 3"?

 

i believe its 2.5

 

its 2.5

 

Check the Coolant temp sensor.

 

you really think thats whats keeping it from running right??? i bet that sensor is burned up

 

If it runs good when cold but ***** out after a few minutes(warm up) it most likely is your culpret, you will be running way too rich and flooding at normal operating temp. When you are cold starting the cts tells your pcm/ecm/ecu/whateverthefuckyouwannacallit it is cold so it adds fuel for better start up, idol, and to warm the car.

 

ok because once it runs for like 45 seconds it will start to shut down and then wont run again after that so...

 

Sounds like either you sensor is bad or the wiring is. One way to test the sensor is to find out what resistance it should have to start going into open loop and run it till it shuts down, then mesure the resistance at the back of the sensor with a multimeter.

 

sorry it took so long but heres a sound clip
