    Hello AZ! Thank for for everything you have done for me! You've been a great help!

    Hello everyone! I'm looking for a full exhaust system for my Audi B6 3.0. I would like to keep it within $1,000 USD and it has to accept the O2 sensor.

    I think I know what I'm talking about, I've done some research regarding this. If you have to correct me please do. I just want something free-flowing and loud. But doesn't break the bank.

    Thank you!

    Billy Boat comes to mind, or you could look into a custom job at your local muffler shop.

    You're gonna be told to search like in the last 10 threads you've made lol. Exhausts dont deal with the 02 sensors. All the shelf exhausts are dp back for the 3.0. OBX or borla for premade less than $700. Or go to a shop and have them make one.

    I'm pretty sure you can use an exhaust that fits the B6/B7 S4 so you can search for a used exhaust from those vehicles too.

    x2. Don't they have some valve by the muffler to make it sound different or something? (OEM ones).

    Is it me, or is the stock 3.0 so quiet it's like you're driving an EV?

    The best performance will come from the Fast Intentions B6 S4 catback, they run a little over 1000 for catback and they sound really good. If you want down pipes as well its going to cost another700 to 1000$ or you can just gut yours for a good boost in performance. And yes any B6 S4 exhaust will fit.

    Any 1.8t downpipe back can easily be modified to work with the 3.0. Cut the y-pipe and extend the pipes. My 3.0/2.7 has a 16601 exhaust.
