    3.0 A6 C7 Exhaust Tuning

    Guest-only advertisement. Register or Log In now!
    Has anyone cut out the last set of mufflers and just ran pipe past them? I was just out back looking at the exhaust; I don't see any reason this would cause issue -- if I were to cut the pipe to test, and it sounded bad, I could just clamp it back. Has anyone done this? Perhaps knows what it sounds like?

    Thanks,
    Kal

    I spoke with my local shop, and they recommenced that I kill off the middle resonator and just X pipe it to the back two mufflers. I'll report back on sound.

    Previous owner took out the resonator, rear mufflers and replaced the mid muffler with a Magnaflow product. I have videos, PM me if youd like to hear it. It's decently loud, thinking about going to the Magnaflow specific exhaust for our cars.

    There are a few videos on YouTube, go check them out. Search for C7 A6 muffler delete.

    I guess my searching skills weren't strong because I didn't see these in my preliminary hunt. Thanks!

    Thanks, but I already made my decision and removed just the one resonator. I had been debating doing the delete or the magnaflow catback, so I think I'm going to ride a few hundred miles with this before upgrading. Cheers.

    For future searchers:

    There's 3 resonators (1 big one towards the middle of the car, 2 small ones by the cat), and 2 rear mufflers.

    I did a resonator delete (middle back) today and I love the sound -- it's about 30% louder than stock, no high pitched noises or backfiring echos. The idle is maybe 10% louder (at max, hardly noticeable to be honest) but after 3k RPM, it really steps it up and you hear it growl.

    Removal of your middle resonator and replacing it with two channels:
    [reserved space for link, I'll make it soon]

    Here's what I did but with an X pipe instead of two channels :

    Here's a few of both the rear mufflers being deleted:

    Pushing the legal limits, another possible configuration is removing the mufflers and the rear resonator:

    Or get a ticket with straight pipes:
