whats the inlet and outlet size of a stock muffler on a cobalt ls 2.2l...?

its time to upgrade...any thoughts what i should go with?

 

I would recommend getting a full cat-back exhaust like the GMPP ones.

 

noted and i will in time just wanna throw a muffler on for the time being

 

Thats cool. I'm not sure of the sizes, but I've heard guys with magnaflow mufflers on their 'balts and those seem to sound pretty good.

 

you do realize that putting just a muffler on your car will do nothing for performance?

It looks like it's about 2.25-2.5 inch inlet

 

i know at thuis time i just wanna change the sound i work at a auto parts place and get stuff for pennys...

just need to to know the size????

 

its a 2.5 inlet. buy it from ebay. i really didnt have much cash at the time and it cost me 30 bucks with shipping. works real good and idle's very soft and quiet...

 

just get one with a 2.25" inlet that way when you replace the rest of the exhaust you don't need to get another muffler. besides, an exhaust shop will put whatever extension you need to fit it to your stock exhaust

 

Magnaflow FTW! You can get it on e-Bay for like $65 + shipping.

 

is it a center in center out or what?

 

this is the biggest rice move ever putting just a muffler on

 

rice is nice lol

answers?

 

i would like to put a different muffler on my car, the stock one is very ugly, but i am saving and very close to the gmpp cat-back

 

center in?

center out?

anyone?

 

i sont know if you could say one way or the other. the stock muffler is a weird ass box shape kinda, so it would be hard to say i do know it is not a strait flow through... i want to say it flows in the right side and out through the left if your standing at the back looking at the car.

 

I've heard that the the exhaust tapers from 2.5" to 2.25" somewhere just before the muffler.
So I'd take 5 minutes to get under your car and measure everything. Then look at your books to pick out a muffler with 2.5" in and out. Go to muffler shop and have them cut out 2.25" section, make whatever pipe you need and install your muffler.

That depends. If the stock system has the same pipe size as a catback you can get roughly the same power increase by just replacing the muffler with a freeflow.

If the muffler is the most restrictive part of the exhaust then you can get more performance by using a less restrictive muffler. But if the cat is where the restriction is, the muffler won't do much more than change the sound.

 

putting a muffler on a honda is the biggest rice move ever.

 

either answer him or shut up, the stock piping is around 1 7/8's inches
