ARH Stepped Headers & Catted Y Arrived!
#21
^ Yes, rear O2 bungs are included on their catted y-pipe as you can see in the picture above, and it is worth noting if you want any extra bungs added like for a Wideband, they typically will add them at no cost...
But you could also put plugs in them and use emulators, or with a tune just delete the ones after the cats, since they are emissions-only and serve no other function.

Yeah that's what I've read because the rears don't really do anything other than be a tattler. I've also heard that even with the rear o2 in place the check engine light will still kick on because they read for stock manifold and car

Yeah idk of if it will or not. I've been reading so many different threads on ls1 tech that it sometimes gets confusing. I hopefully plan to order my set in about a month. That will give me time to get my ls6 intake already to go on. Gonna sand it smooth and paint it. Who did you go thru on ordering the headers?

So the SS is out of the shop -- more muscular sound and feel, and no SES codes thus far! As the picture below implies, the fit is tight between the 1 7/8ths section of the headers and the K-Member on the driver side. The result is the headers touch and make noise at some points with certain movements and RPMs due to this, not sure if this is a convertible-specific issue -- maybe I should have stuck with 1 3/4... The shop did a little grinding of the K-Member corner, but it will have to go back for some more adjustment. I am also going to phone ARH to see what they have to say...
The Noweeds diverter is top notch -- very nice operation, fully automatic, wicked sound.

Looks like the solution is the grind the $&!+ out of the K-Member in this area of touching from this post: LS1TECH - View Single Post - American racing headers 1 7/8 and starter doing battle!!!!

Yeah I don't want grind on my k member I plan wayyyy down the road when the 98 gets pulled from daily duty to pull her apart and do everything. Because I'd like to have a bone stock camaro (68) and one where there's no much stock left (98) besides my 98 is a base ss no other options doesn't even have leather just good ol cloth
