FS: C6Z06 LG 1 3/4" Longtube headers w/ high flow cats and X-pipe
I am selling a set of LG 1 3/4" Longtube headers with high flow cats and X-pipe. These headers are recommended for any C6Z making around 550whp or less. The added peak power for a 1 7/8" header can lead to a loss of low end torque and acceleration. After talking with LG about my header design, I stuck with these headers with my current cam only setup, but now that I am planning to add heads and nitrous, I will be needing to go up to a larger diameter pipe.
The car has went 10.62 with these headers at 134mph along with an intake, ported LS7 intake manifold, and a cam. Stock clutch, heads, exhaust, etc... I have been amazed with these headers for the car. The sound is excellent, and the low end grunt has helped me numerous times just jump out in front of other C6Z's making more power than I am. Again, I wouldn't be switching to a larger pipe if I was content with my current 550whp setup because these pipes are simply excellent.
I am asking $1100 + shipping and am located in the Houston area for local pickup if desired.
I am also selling my Fasterproms Stage II Ported LS7 intake in a separate thread if you are interested.
Thanks,
Scott

To answer PM's received.
These pipes are coming off this weekend and will be ready to ship on Monday. Pics will also be posted upon the removal of the headers.

Headers are off the car and ready to ship.
During the removal, I found out that the catalytic converters have been welded on.

I dont think this is true. I bought a set of LG's off a guy with a 2010 GS, and I have a 2008 LS3. The headers fit, but the x-pipe needed to be changed out for an older style. The cradle design for our cars changed after 2008, which require a slightly different bend in the X-pipe. I would call LG before committing to any purchase, as its a huge pain to go through everything I went through. With that said, I can't comment on the difference between the pipes for LS3 and LS7, again I'd just call to know for sure.

I just contacted LG. They said that the headers would fit, but that the last 2 feet of pipe would have to be adapted to fit whichever year of LS3 you have assuming that you are still on the stock 2.5" exhaust. The 2008 and 2009 model years are different. The price for the rear pipes from LG is $289 for whichever year you would need, but you might as well just buy a new set of headers honestly. No need to spend $1000 on my pipes and $300 to make them fit.
So unless you are running an aftermarket muffler system that is a full 3" design, then they would probably not work. If you are running a full exhaust already, then they should work.
