Which header for LS2

Le Mans Master
If you keeping the LS2 heads, even ported, run a 1.75" header. It will make more power everywhere on the LS2 than the 1 7/8" header.
Good luck!

Ohh. They probably did too much inner porting after they welded the tube. If its a really thin break in the weld the carbon might seal up the holes enough so they arent leaking anymore. Or, if they only leak at WOT it might not matter since the car goes into open loop anyway and ignores the O2s.
That is prtty terrible that ARH won't honor it though. I can understand a defect since i believe the porting is done by hand after its welded, but they should stand by their products.

$155 on the auction site....fits great, SS, TIG welded, all O2 extensions and hardware included. Stolen from another design, but every long tube design was stolen from W2W which is no longer around

I have ARH 1.75's with their catted x-pipe on my 07... unfortunate about the other posts to the contrary, but mine went on & fit like a dream, tucked up extremely nicely in the tunnel, with the rear O2 sensors slanted in a very well-thought out fashion (& I'm an engineer). Flange seals are good, & this guy is EXTREMELY happy that I went the extra expense for the excellent fit & finish.

I was all set to pull the trigger on a set of OBX headers, but I was nervous due to a few of the negative threads I saw here and elsewhere (overall reviews do seem positive though).
I read the fine print and the eBay ads for everyone selling the OBX package stipulated that the buyer was responsible for covering shipping both ways and a 25% restocking fee, no matter what. This didn't sit well with me, as I know I'd be mad if I got a crappy set and had to pay a couple hundred for them to fix an issue which was in no way my fault.
I decided to check out Maryland Speed, who made me a great deal on Kook's for my CTS-V. They're running a couple package deals on Kook's and Halltech or Vararam intakes which I was considering. Then a chat window pops up and....we'll just say they made me an offer I couldn't refuse
Yeah, my wallet is quite a bit lighter, but I'll sleep better knowing I have quality parts on my vehicle and that I have two great companies backing me up should a problem arise.

the ones I bought are out of stock but they told me they are expecting more. The seller is "awesomecarparts"
Mine fit extremely well, and came with clamps and o2 extensions.

Personal experience with my C5 with ls2 swap. Originally has LG 1 3/4 castles and car felt good, but the lower primaries had accumulated some damage, one was 1/2 flat. So I went with one of the cheaper options for LTs in 1 3/4, and found that the LT lengths to be a fair amount shorter, also the car felt bottle necked. Immediately removed and installed a set of Stainless Works 1 7/8 and the car was better than ever. If I had to do it again I would go 1 7/8 or 2 inch primaries.
220 TFS, FAST 92, vindicator cam, 60lb injectors and a Vararam. Good for 471hp on a conservative tune. Same setup but in a GTO and different tune netted 439.

I ran 1 3/4 ARH W/High Flow cats on mt 06 LS2, install was easy and never had an issue with any leaks.
Car also had Trick Flow As Cast 220's, Yella Terra Rockers, 235/239 Comp Cam, Fast 102 intake, ported TB and a Vararam and put down 503/447
I have installed Kook's on several cars, I like them as well.
