    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    Found brand new set of chrome valve covers and set of used headers from an olds 350, will they fitan olds 307?
  2. Kooks Headers Installed-Selling custom 3" cat-back

    2009-2015 Cadillac CTS-V Performance Mods
    I had the Kooks headers installed today at Behe Performance. I went back to the stock mufflers because I was afraid they would be too loud. To be honest...I am kind of disappointed in the sound compared to my 3" custom cat-back. The only good thing is that there isn't any drone in the car. But...
  3. Want to upgrade exhaust

    2009-2015 Cadillac CTS-V Performance Mods
    Looking to upgrade my 09's exhaust. While I'm at it "thinking" adding headers and modified (sufficient enough to get me thru inspection) cats too. There's a lower pulley upgrade in the future. :yup: Knowing the Corsa's have low drone technology, having used a set on my 03 C5 Coupe, at idle I...
  4. NEEDED: Oil pan for '88 Hearse w/ 307 Olds!

    RWD 19xx-1984 DeVille and Fleetwood,1985-1996 Flee
    Anybody know where I can find, or does anyone have an oil pan for an 80's Olds 307? The one on my '88 Hearse is bad... I can't find anyplace that sells them... except for the Chevy Dealer, and its $190! There has to be another place to get one. Even a nice used one would work... Even my...

    space is very limited, doubt ill find a set that fit but if not where is a good place to start making my own?
  6. Gains from headers ONLY

    2009-2015 Cadillac CTS-V Performance Mods
    All seem to claim "30-40 RWHP," but when you look more closely, it's with only two or zero cats and a "minor tune" to "bring the AFR into line" and/or to "suppress CELs." Hmm, sounds like a "tune" to me. So has anyone done a baseline dyno run WITH a tune and whatever parts but NO HEADERS and...

  9. Katech Headers - Note to Self

    2004-2007 Cadillac CTS-V Performance Mods
    Note to self and to the other two guys that ever bought a set... Driver rear-most plug wire will burn through after 10K miles or so. I personally tested it so none of you would have to later. That is all.
  10. Just got my Kooks headers + off-road pipes installed

    2004-2007 Cadillac CTS-V Performance Mods
    WOOOOHOOOO!! Wow these things are so awesome! :worship::worship: I bought the Kooks 1-3/4" Headers with off-road pipes from Paschal Performance for a GREAT deal. I already have a Magnaflow exhaust and this all went on an 05V. The sound is so much more guttural and throaty. I remember...
  11. Headers + Factory Exhaust - Options?

    2004-2007 Cadillac CTS-V Performance Mods
    I've read through here quite a bit, been looking at a Corsa exhaust but have decided to possibly try a set of headers and either high flow cats or cat delete with OE exhaust. I come from the Subaru world were cats need to disappear to make decent power, but then again A. its not green B. sound...

    I've seen a few posts about headers but no actual reviews from owners. My next car is going to be a be an STS-v and I'm planning my mod program now. Headers seems like the hardest part to find.

  17. The correct order/timing for cam, headers, exhaust, and tune

    2004-2007 Cadillac CTS-V Performance Mods
    Hey all. Newbie here...I've read as much as I can on the forum, but still have a few questions. I have a completely stock 05 ctsv. I eventually want a moderate cam, headers, high flow cats, and exhaust (which will be stock mufflers with a cutout just upstream of them). I'm curious what order...

    2004-2007 Cadillac CTS-V Performance Mods
    I was able to get a good deal on a complete B&B setup from a member here (thanks Matt). B&B headers straight through to the X pipe, it sounds phenomenal! I have a few things I wanted to mention so that if anyone else is doing the install they will have a few pointers to reference. BTW for the...
