yes i am reviving this thread.
only to ask if there is any ******* way to get this **** to work without having to spend a shitload of money on getting the **** welded here and there.
or would it make more sense for me to get a 2.4 AUTO dp and just gut the cat

well im gonna fight this ******* thing to the death. lol
im going to see if i can pick up some header wrap to wrap around the sway bar then tomorrow after work im gonna take some clamps and pull up the second exhaust hanger to the chassis. it should give me an extra inch that the cat will be pulled up.
theoretically. but we all know that nothing goes as planned on the cobalts. :frown:
or is there anyone thats local to NJ thats willing to sell a 2.4 DP for the auto trans. i'd just get the cat gutted anyway. no sniffer tests at inspections stations, otherwise i would also get a nice 10k fine for deleting SAI as well. lol

BUT its the only DP that will fit a 2.2 auto with no problems.
how big is the LSJ? 2.5?
nvm i found the answer.
but the real question i have is other than the cat hitting the sway bar and it being a tad short. which was no problem cause we just pulled the catback forward.
so if i get a skinny cat like a magnaflow which is only 4" high it will fit and i will have solved the problem?
or should i just get the 200$ dp i saw last night
i dont remember where though.

theres no problem with going with AFTERmarkert header and dp's
we're talking about using the LSJ dp. which has a cat thats the size of a human head. its a decent amount bigger than what was on my 2.2 stock. THATS the real problem. cause then the cat sits on the front sway bar when you drive.
aftermarket dps all have other small pod cats or that magnaflow 4" tall high flow. the stock LSJ cat is ******* huge.
heres a link to the XTC dp with the LSJ on the left. look at the cat size compared to an aftermarket high flow. https://www.cobaltss.net/gallery/fil...edownpipes.jpg

Correct...this thread is about using the LSJ DP on an auto equipped Cobalt (or G5). The LSJ DP is shorter than the auto cobalt DP, and the size of the cat -- with the way the first pipe bend is -- keeps it from being a "bolt-in".

do you think switching the cat out with a small magnaflow one will solve the problem? or are there more problems than just the cat hitting the sway bar?

On my Cobalt the LSJ DP caused the cat back exhaust to be pulled forward enough to make it hit the body -- as well as the Cat resting on the sway bar so I could feel the exhaust as much as I could hear it.

Here's a clearer shot of how short the LSJ DP is than the LE5 auto DP -- also notice that the first bend on the LSJ DP is near the manifold connector while the first bend is near the Cat on the LE5 DP:

The LSJ cat is a high flow cat that still meets federal emissions requirements and keeps the HO2S -2 sensor happy...switching cats will just provide different problems...the O2 CEL for example.

thats wierd. i just looked at my dp and the cat is about 2" away from the sway bar. cant see how the lsj dp wouldnt fit. seems like theres alot of space there. also the bends above the cat are to the drivers side and not the bottom which makes it look like the whole dp is going to the drivers side a bit and not straight down. i have the xtc dp and pretty soon will be installing it. ill keep you guys posted but i think the xtc dp will bolt on with no problems

I think you will find that the XTC DP will be shorter than the auto DP -- unless they have been reading this post and made one for the auto. The cats on the aftermarket DPs are smaller and therefore not a problem. On YourCobalt (website) there is a Cobalt owner who had to have his aftermarket DP lengthened because it caused his cat-back to pull forward and hit the body.
