    I've seen the term "muffler delete" on a few youtube videos of the E46 330 exhaust, as a way to make them a bit louder.

    Does anyone know what exactly this involves?

    Do they remove the rear cats somehow and replace with a straight pipe?

    Or hollow the cats out or something?

    (I'm assuming the yank term muffler translates to catalyst converter?)


    Just wondering if its a feasible option or not.

    What rear cats? . In you case, it's a question of replacing the silencer (muffler) with twin straight pipes and turning off the vacuum actuator .

    Sorry I was getting cats and mufflers confused.

    When you say replace with straight pipes, do I just take it to a custom exhaust place and get them to chop the silence out and put some straight pipe in its place?

    Or is there a more elegant solution?


    Thanks

    if you want a bit more power you can remove the cats and get a replacement section ie de-cat, if you just want a little big more noise then turn off the vacuum actuator, if you look under the rear of the exhaust you will see a pipe going to a valve pull it off and this will keep open the valve inside one of the exhaust pipes, this will make the car sound meaty on idle and up to the powerband

    Yes, better to take it to a specialist. This is what it should look like after the conversion....done on a 318 with a single pipe to twin tips.
