    I don't think I lost any Hp (ok maybe 1.2) with my B&B 1-3/4" headers. So maybe I would be at 514 rwHp instead of 513......that's about 0.2% loss. Think about that for a second.

    Ok, so what hardware are you guys using to bolt these headers up, ARP im assuming, with locks or no locks. it has been my experience with headers they leak,if not now they will leak later.

    I'm looking at the Pacesetters with the ceramic coating, but also need cats (to pass emissions) and already have magnaflow cat back. what do you recommend gentlemen.

    I guess I will need extension O2 leads as well for the fronts, or will I need all four to be extended?

    PS: Happy New Year !

    Unfortunately I can't be of help on the bolt question. When I bought my red headed step child in July it was all done up by modern muscle out of the Chicago area. But, when installing the clutch late July it seemed there was no o2 extensions for the back. Happy new year also! Speaking of exhaust !! Since a recent view of pisnuoff video of cutouts I will be ordering tomorrow....damn it...

    I'm not sure where the header has the bungs welded in but I didn't need extensions for mine. I have the Stainless Works exhaust and the O2 harnesses were BARELY long enough.

    I am using ARP 4341301 studs. I am also using Percy's seal4good gaskets (for LS1 I believe).
    Does PA do the full visual and emissions inspection, or do they just connect OBDII and see if you fail by having cats not warmed, not working, etc? I passed NYC inspection with no cats because I had them tuned out, which made them read READY and passed inspection

    You shouldn't need extensions for the fronts, but you will for the rears.

    Im in PA with pacesetters, no extension needed for the fronts. Rears turned off and deleted. High flow cats welded in with stock resonator and muffler delete. Car passes inspection with ease. I used stock exhaust gaskets and header bolts.

    Thanks, PA is both OBDII read and visual inspection "unless under miles 5000 then exempt from emissions.

    My catless B&B was a custom gut job. A big screwdriver scraping out the cat(StealthV had blown one out and I gutted the other when he practically gave them to me). So even though MA is OBD-II only, it would pass visually, too...

    Allentown, We should get together sometime as I'm about 40 minutes from you. I'd love to hear your exhaust and compare mods. My V is put away for the winter already, I don't know why I do it so early with the mild early winters we have, damn I miss driving her.
