welcome to ls1... for what i have learned about this cars is that shorties make no difference on this cars.. longtubes or stock.. only options you got.
some states like cali, longtube headers are illegal bc the cats have to be relocated from stock position, what i mean by that is that you have to find out if that could be a problem in your state for emissions test.
LTs headers are bolt on, some brands have some fitment problems but that is on your budget, cheap headers usually have this problems alot, kooks and all those expensive brands have no issues on fitment,, very rare that one doesnt fit right..
a good brand is also pacesetter a good option and very good price.
the catback should work fine, but you need a Y pipe that fits those headers.. either catted or with no cats..

how much you looking to spend on headers?

As stated, long tube headers are the way to go on our cars. Stainless is a bit more $$, but they hold up great and will last forever. Let us know what you are thinking of getting and someone on here can give you real world feedback on them. I personally run Kooks headers and a Kooks catted Y-pipe on our car together with a Magnaflow catback and an electric cutout. One thing with LT's -- you'll want to grab a set of Bosch P/N 13111 O2 sensors as they have a nice long harness. Running extensions or cobbling up your own harness is generally asking for problems.

to answer the other part of your question.....the way it works is each header manufacturer typically manufactures it's own Y pipe. The Y will run from your headers back to your existing catback's I-pipe. It will connect pretty much in the center of the car about where the rear seats are.

get a set of bbk headers with ory for 360 bucks, can't beat that price plus the fit really good i install then in both camaros and trans am they always fit good takes about have a day with a couple of buddy's and jacks to do. Not hard at all

Pacesetters LTs is what ive ran and had no issues what so ever. Just depends on what you want to spend and to what your emissions will allow you to get by with. you can buy the headers/ory combo or if you have a decent local exhaust shop they may be able to build you one cheaper.

Pacesetter are a good bang for your buck. You have many options on whos to buy or go with, but definetly get longtubes, anything else is a waste of money becuase you will end up getting longtubes in the long run.

Dont waste your time on shortys....theres a lot of options out there Ebay,Pacesetter,etc,etc....You'll need ay ipe for the LT's your catback is fine.

**0rion** · 12-14-2011, 07:01 AM

if you have an option to make a Y pipe or if you can find obx on ebay with a Y that would be the direction I went.

**beerboy** · 12-14-2011, 02:15 PM

Im in the same boat as our poster...I would love to install headers and a y-pipe but dont like the raspy sound of some that ive heard, so maybe just a gmmg catback (sounds awesome). also, do i need to get a tune if the exhaust is changed or is that just if anything on the intake side changes? will my engine light come on? Ive done the "free" mods to the car and some say it will run lean without a tune..is that true? any help would be great!

**scott5** · 12-14-2011, 05:12 PM

No tune is needed with an exhaust change.

I wouldn't say that. Perhaps with just a catback.

Once you install headers, Y pipe and a catback and got rid of one or all emission control devices your check engine light will come on. You also have a much better flowing exhaust and a tune will help you get the most out your mods and will get rid of those SES lights. Is a tune required for the car to run after these mods, no, but to get your AFR straightened out you will need a tune.

**pajeff02** · 12-14-2011, 06:10 PM

^^ This. Anything that changes airflow through the engine will have an impact on its volumetric efficiency -- headers, intake, heads, etc... Yes, you can run some mods without a tune, but you will be leaving power and efficiency on the table (no pun intended).

after doing the headers and ORX on both my cars, I put the rear o2s back in w/o cats and i dont have codes showing at all. Hooked it up to my computer and ran diagnostics on it and didnt change anything even at WOT.

**pajeff02** · 12-15-2011, 03:37 AM

Maybe the rear O2's were already tuned out by a prior owner or they are toast and show the PCM what it wants to see.

**matt evans** · 12-15-2011, 04:14 AM

there not toast there still sending signals to the pcm. Idk may just be wednesday cars i guess but im curious to see someone else try it to see if the results are the same. 2/2 so far for me on mine. Ill try it again on my buddies SS when we tear into his h/c/ install.
