hey guys i was wondering if anyone has a good picture of what the stock 06 cobalt ss exhaust looks like. i ask because i bought my car used and i have been wanting to mod the exhaust on it however i am not exactly sure if anything has been done to it. just by looking at it i can tell the headers are not stock so i was wondering about the rest any pics would be a great help thanks fellas

 

if there is a resonator after the cat, the exhaust is rusted to **** and you have a bigass muffler with a polished tip and its all one piece (no badclamps) then you have a stock catback

 

Post pictures of your exhaust and I'm sure we can tell you if it is stock or not.

 

im not home right now but it looks like my question is answered their is no clamps on it and its rusted to ****. when i get home ill get as good as a pic as i can and put her up here to see what you guys think.

 

I'm home and i have a pic however i don't know how to upload it to here

 

photobucket...

 

never used it

 

make an account in photobucket, upload the pic, get the img code, paste on here

 

Use my writeup as a guide. You can check your sizes against this and confirm if its stock or not.

The LSJ exhaust is not 2.75", not even 2.5", it starts off at just a bit over 2". I was running my turbo downpipe to this for sometime and it barely fit but did bolt up. I have since replaced my catback with a 3" system.

The downpipe bolts onto the stock 2 bolt flange but sadly the entire catback is restricted starting with the 2" opening into the resonator.


The exit to the resonator is 2.6"


Pipe after resonator is 2.49"


Pipe after resonator then shrinks down to 2.23" before entering the muffler


The muffler opening is 2.23"


The muffler exit is 2.49"


These are all OD dimensions meaning the actual ID of the pipe is even smaller..

looks stock from what I can see

 

not stock, but worse, they dropped the cat down to what looks to be a 10 inch section of 2 inch pipe. Nice and restrictive.

 

stock downpipe.



OP's DP looks more restrictive than stock.

 

so from what it looks whoever put the headers on didn't know how to connect it to the stock pipe so dropped the pipe size?? anyone know a good and loud but poppy exhaust system from headers back?? and possibly a video i could hear it in??

 

search for exhaust clips on youtube...

You need to get rid of that restrictive cat, mid pipe, and stock resonator. Put in 1 piece of 2.5 to match up to the rear pipe, if you dont want rasp install a 2.5" resonator from a new high flow cat back to the stock 2.5 inch pipe. It will be all you need for your stock supercharger, even with mods. This can be done at a local exhuast shop for 100-200 bucks if they arent total rip offs.

 

I'm going for loud and poppy

 

get the noodle header

 

i got headers i just need a nice loud headers back setup

 

the jbp header is complete garbage

 

Anybody know anything about loudmouth 2 exhausts for my car I've been looking them up and they sound good on YouTube but any comments on quality or sound?

 

go look at the zzp stuff quality pieces slp loudmouth is not that good and if you search there hve been many reviews on that exhaust
