    Cadillac ATS Performance Forum
    Hey guys hope everyone had an exciting halloween night!

  2. Tuner options?

    2004-2007 Cadillac CTS-V Performance Mods
    Sorry, tried searching but it wasn't working at the time. What options are available for tuning. Do any companies offer a "canned" tune thats worth anything for these CTS-V's? Just picked one up, and all it has so far is a K&N intake, and Corsa exhaust.
  3. Odd tranny problem after installing exhaust

    2009-2015 Cadillac CTS-V Performance Mods
    I installed the KPE cat-back this weekend in my garage, 1st off it sounds great, ok now to the problem. When I went out for the post-mod test drive, everything was going great until I put it in sport trans mode and tried to use the paddle shifters; got NOTHING. No light up in the dash, wouldn't...

  5. Dyno results - Stock ECU vs. W4M retuned ECU after Kooks install

    2004-2007 Cadillac CTS-V Performance Mods
    A couple months ago I finally got my Kooks headers installed, after having them for a year or so. I didn't particularly want to do a mail-order tune, and while I was stationed out in WA I just didn't have time between deployments to find a good tuner, so the headers sat on my family room floor...

  7. Classic rap recommendations?

    Community Lounge, Introductions and General Discus
    Recently, I've been listening to a lot of NWA (straight outta compton) and really like it. I've got some other classic rap in my iPod, but would like to get some more of the good stuff. So what kinda stuff is good from this era (late '80s-mid '90s is what I was thinking)
  8. 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...

  12. Decision time...Mod the CTS or get a V???

    Cadillac CTS First Generation Forum - 2003 - 2007
    Ok so here's the situation... I just got a new job and need to decide whether to save up for a little while and get a V, or get to modding the CTS I have now. If I were to sell my ride (probably worth around 13k) what price range would I be looking at for the V? I figure for now I will go ahead...

    2004-2007 Cadillac CTS-V Performance Mods
    So I saw the thread about problems with the V (engine mounts, rear ends, etc) But I had a few questions if I were to get into one. 1. How often do the rear ends break? And when they do, what price am I looking at? I have a 600hp Audi A4, and the drivetrain is pretty solid, but I want something...
