    STS-V Intake Baffles

    Hey I'm under the hood of my car right now. I'd like to remove the exhaust baffles to increase blower whine. Any reason I shouldn't do this? Where exactly are these baffles? Explain baby style please.

    Do yourself a favor and install the Spectre CAI setup. Its my first mod and I installed it today. It looks good and really wakes up the supercharger. Sounds AWESOME!

    Take the big Y section of the intake off. The baffles are slid in from the back. Just pull them out. It's easy.

    Re: STS-V Exhaust Baffles

    Sorry. Are you talking about the "y" that's formed when the intake pipes split and go around either side of the the supercharger/engine before meeting back up again behind it?

    Re: STS-V Exhaust Baffles

    Ill eventually end up with the intake tim developed. The one that eliminates the restrictive y altogether.

    ----------

    So after the pipes split and just past the supercharger, those 2 clamps on each side, and the one clamp at the beginning of the y (nearest to the grille). Is there anything else I have to remove to get the y off? I imagine its bolted down somehow. So ill be able to access the baffles right by where the double clamps are right?

    There are some bolts that hold the y section down. Just get in there and do it. You'll figure it out.

    Re: STS-V Exhaust Baffles

    It's pretty easy like Tim said... Just start at the front clamp and work your way back. There's a few bolts on either side that hold it down but nothing tricky.
    The hard part comes when you go to install Tim's intake. You'll have to remove the rear Y section at that point. I think I left 1/2 pound of flesh back there getting everything out and getting Tim's to fit right. Love the results though.

    Doesn't removing the baffles upset the flow of air across the MAF and set a code??

    Re: STS-V Intake Baffles

    My understanding is that it doesn't affect the car performance wise which leads me to believe that no, it doesn't alter the air flow. Someone who knows more will answer. This would be a deal breaker for me.

    Thanks for that rob and thanks gizmo for fixing the name of the thread.

    Nope its after the MAF. They are in the mufflers by the supercharger.

    Re: STS-V Intake Baffles

    Removed the baffles yesterday. Big difference. So far I like the change. For those in the future who want to do this you'll need a deep socket 3/4 inch for the strut bar and a deep socket 10mm to unbolt the y portion of the intake. Also a flathead screwdriver to loosen the clamps. Easy job.

    Re: STS-V Intake Baffles

    Old thread but I thought this would be the best place to add to since it comes up in searches.

    Changing out the plugs in my V and pulled the tubes/baffles out of the stock intake. I'm wondering if a better option would be to replace them with solid pipe of some kind? PVC pipe maybe if I can find a matching size. I pulled mine but was thinking it will disturb the air flow too much when I see what's left inside the hollow cavern inside there.

    I need to keep a stock appearance on the vehicle since I have a lifetime powertrain warranty by the selling dealership that I'd like to keep. At 15-20K miles a year on the V, it won't be too long in the future before I'm turning over 200K miles (102k miles now).
