    Re: Best exhaust option

    That's not what I wanted to hear. I bought it for 2 reasons. Had less than 1/3 the miles of mine and I was able to get a warranty on it. I don't want to compromise that. I was kinda hoping it was one of those things where the tech wouldn't be able to tell its not stock headers.

    ----------

    Oh and after you said that I looked you up. Didn't see anything on the new car but I saw the older one had the magnaflow. Figured you were being funny.

    Guy how long is the warranty good for?


    It might make sense to wait until you are back in NY and talk to a couple of caddy dealers and see if you could get something from them about if they would cover the engine even if there were aftermarket headers installed. Perhaps see if the CTS-V guys know of any "mod friendly" shops in the area.

    I might consider driving how you want for about 50% of the warranty to basically work out the kinks in the car and then start modding and roll the dice a bit on if something breaks due to a modification.

    Re: Best exhaust option

    I'm going to go with no. My friend works at a caddy dealer and if my car goes in he's the one that works on it and he had to convince the service righter that my car was stock. Only visual mods are CAI and exhaust. The exhaust has gmpp right on it. But they still did not want to cover the cats.

    There are a lot of other things that the warranty will cover outside the engine so just mod it and don't look back.

    Or keep both Vs and mod the old one.

    Re: Best exhaust option

    Haha nah I'm not keeping both. I'll talk to caddy dealers. I'll hit up the cts-v forums. Warranty is good until 2018.

If you did this and then floored it, it would drone up until about 55+ mph. If you didn't floor it and just accelerated moderately, (you're probably not in a rush if you're shifting to 6th at 43mph anyway,) while in 6th at such a low speed, no drone. Low speed + high gear + full throttle = drone. Basically it's a non issue.

    The exhaust sounds absolutely incredible at high RPMs in person.

    Cruising on the highway? No drone issues. Anytime you would normally hear the exhaust when you're driving, imagine it being a bit deeper with the GMPP.

    Hard acceleration stock: http://www.youtube.com/watch?v=fbo5DSOW82A
    Hard acceleration with the GMPP: http://www.youtube.com/watch?v=Pza3I...ature=youtu.be

    Moderate acceleration stock: http://www.youtube.com/watch?v=AhS8PPRQ_KA
    Moderate acceleration with the GMPP: http://www.youtube.com/watch?v=Y7s1t7Q1ULY

    Any wobbling noise you hear in the stock videos is a bump on the tread of one of the tires. New one should be in early next week.

    I still owe you guys startup sound from the outside and acceleration from the outside.
    Not bad but after hearing that I still think corsa sounds better.

    Also side note thought the V would not go into competitive mode with a bad tpms sensor. I see your light is on.

    Good catch. Wasn't a bad sensor. Absent minded shop that forgot to reset the sensors after swapping tires from one car to the other.

    Re: Best exhaust option

    Just did a quick search in the manual and maybe I missed it but where does it say that competitive driving mode won't engage if there is a bad sensor? I know not everything makes it into the manual sometimes too.

    Re: Best exhaust option

    I read it on here.

    I do not own one so I cant lay claim as to if it does or does not for sure.

    ----------

    Seems to be true on the CTS-V
