  1. MPG loss after aftermarket parts install

    Cadillac ATS Performance Forum
    I put in an aftermarket air intake and exhaust system onto my 2016 ATS and now I’m getting about 5mpg anytime I’m hitting the gas to accelerate. I’m not putting my foot down or anything like that and the turbo is producing around 5-8 psi of boost. I’m wondering if there might be an issue with...
  2. Has anyone tried upgrading their exhaust that Cadillac provides from the factory?

    Cadillac ATS Performance Forum
    I was curious to see if anyone had installed the exhaust upgraded kit, dual exhaust (22798566) from Cadillac. I was thinking about getting it installed. Has anyone ever had it installed from the factory or installed later on?
  3. Muffler delete 2009 3.6L DI AWD sedan

    2008-2013 Cadillac CTS Performance Mods
    Sounds amazing, very low note for a V6. Drones a little on the highway but not badly. I love the pops and crackles when you let off. I just cut the mufflers off and welded in pipes leaving the stock exhaust tips in place, it was really easy because the tips have hangers right behind them...
  4. Does minor exhaust modification void warranty?

    Cadillac ATS-V Series Forum
    Expecting to be flamed for this, but the exhaust drone from my stock ATS-V 8A at low speeds is getting on my nerves and I'd like to some silencers or additional resonators to quiet it down. Is it safe to assume this will void the factory warranty? I've considered less invasive options like...
  5. WTB: V2 Stainless Works Exhaust

    CTS/CTS-V Parts For Sale
    Hi All, I have been using the OTP cutouts for a while, but I am getting tired of the drone and vibration from it exiting under the car. I would like to find a good deal on Stainless Works header back system. Hoping for a S tube mufflers, but open to chambered as well. I am located in San...
  6. 2014 ATS Engine Fire - Need connector identified!

    Cadillac ATS General Discussion Forum
    Had a small fire between the turbo and the firewall. The fire charred a few things, but I'm unable to identify a badly burnt connector that I'm sure will need replacing. Any help or photos would help a great deal. Engine also throwing a P0171 engine code which I imagine has to do with the...

    2009-2015 Cadillac CTS-V General Discussion
    Ugh, I saw you at the last possible second. You looked lowered and may have had some exhaust work. Or maybe not. And I couldn't tell exactly what color you were but it looked similar to Stealth Gray...
  9. 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.
  10. 1997 Eldorada catalytic convertor do front flange bolts have springs for flexing ?

    Cadillac Seville / Cadillac Eldorado Forum
    The front flange of catalytic convertor bolts directly to exhaust pipe flange of motor. Engine pipe has a flexing bellows built in but I feel catalytic convertor should have flex springs on clamping bolts for further relief of flexing what is stock? Thanks

  12. I have a sound that needs identifying too..

    Cadillac Seville / Cadillac Eldorado Forum
    On ETC, when I floor it from a stop, there is a split second groaning noise that is similar to the sound traction control makes when active, or ABS -- however there is no accompanying shudder. The car shifts fine and runs fine -- however it freaks me out and I let off of the gas. If I take off...

    Just picked up a new 2010 CTS AWD 3.0L. Anyone installed one of the numerous performance chips that are available online and claim big HP and gas milage gains? What about intakes? I see KPE offers one on here. Any feedback is appreciated!

  15. Burned Out on Exhaust Research

    2004-2007 Cadillac CTS-V Performance Mods
    I really need an exhaust upgrade and I've spent weeks watching every video on youtube, myspace, facebook, and streetfire at least a dozen times. I've changed my mind between stainless works, magnaflow, b&b, and corsa at least a dozen times also. I think I narrowed it down to the B&B. I need...
  16. Car hit with an Egg at the store!

    2009-2015 Cadillac CTS-V General Discussion
    What a Sunday morning treat. Came out of the local store here and found that someone had thrown an egg at the front of my V. Anyway I've used 3m Wax and the yolk part is completely off. The problem though is where the impact of the egg took place in that there is a spiderweb like cracks with...

  18. Went to the fabric store.

    Informal Lounge, Introductions, General Discussion
    Nice day outside. 50F+. Walking into a fabric store with a pink shirt on after parking a little convertible... it just looks wrong. The only other man in the store was a gay guy, and he made it obvious. Bought some black vinyl, upholstery glue, and padding material. Half off! Got it all for...
