Well just got back from an exhuast place to diagnose this leak ive had for over a month. A few days ago it got really bad, so i finally took it in. Its the downpipe, its fucked, the flex pipe is torn up and exhuast is pouring out of it.

EDIT: Got an LSJ downpipe coming in now, thanks to Doc

xtc makes a downpipe for the stock lsj/2.4 manifold.

Now the question... should i run with or without a cat. My car doesnt go through emmissions until 2014 so i can worry about that then. BUT, would the car then throw a code if i dont have a cat....

get a cat

_UnLiMiTeD_

but...but... its like $100 more for one of the buggers! lol. Any group buys out or sales on a catted downpipe?

Also why u say get a cat?

olivecj

Yes get a cat bro trust me your ears will thank you for it. Plus the hp difference is little to nothing and when your safety is up you wont have to add anything to pass.

car sounds like ******* **** unless you put a huge resonator on it

_UnLiMiTeD_

i have the stock resonator on my car, the thing is pretty damn big lol. I also have a big 18" magnaflow muffler, fairly mellow sounding car...

Im not thinking of catless for performance, just price.

trust me, ive had more exhaust combos on my car then anybody i know, the stock resonator is ****, your car will sound like ass with out a cat unless you get a ultra quiet resonator

or you could just get a new flex coupler and have a custom exhaust place weld it on for you, thats way cheaper

_UnLiMiTeD_

bleh, i could get this put in myself to save all the labour, much rather just get a new downpipe, i race the car anyways, so wont hurt to get a bit better performance out of it while im fixing it.

So any vendors got any deals for a downpipe?

olivecj

I dont think anything is on sale right now , but maybe if you call the site they might give ya deal.

_UnLiMiTeD_

yea i will have to do some searching, hoping a vendor see the post and see if i can get a decent deal on one.

no vendors interested in making a sale?

Why not try to get a used SS/SC downpipe? Bigger tube, bigger converter, and will fit a 5-speed Cobalt perfectly...and no DTCs.

_UnLiMiTeD_

exhuast on the 2.4 and the 2.0 are the same i beleive. Different on the 2.2's

D4u2s0t

the 2 or so hp you will gain from going catless will absolutely not be worth the cost savings, imo. You will get zero noticeable performance gains, and it will sound like ass. I would get the cat. Check the for sale forums, most people sell their dp's for about 50 dollars plus shipping. If you don't have other exhaust work done, don't get an aftermarket downpipe if you're concerned with how the car sounds.

_UnLiMiTeD_

i got a magnaflow muffler, i dont mind it being louder, just cant afford to do a full exhuast.

D4u2s0t

not just louder, extremely raspy and bad sounding.

_UnLiMiTeD_

a catted aftermarket downpipe is not that raspy, a catless one is fairly raspy, i been in both

Dave7417

Red has the right idea. Get a LSJ downpipe. I have one, and it is surprising the difference

Manifold is the same. Downpipe is different. (2.4 is smaller diameter.) Catback is the same.

Red07SSNA

SS/SC Downpipe tube is 2 3/4" and the Cat is approximately 60% bigger
2.4L Pipe is 2"

my AUTO equipped 2.4L DP on top, SS/SC on bottom:

_UnLiMiTeD_

ahh cool, i take it since its a bit bigger, it will be a bit louder then the 2.4 DP, i dont mind, just wondering.

Thanks for the pic

_UnLiMiTeD_

Any comfirm on the sound? I dont care if my car is louder im just curious since the lsj DP is bigger then the 2.4, that it will be a bit louder?
