    The cheapest way available if you don't watch them.

    You can get brassing if you specify it.

    Just about all aftermarket pipes are slip-on pipes that you clamp on. No welding required.

    From the line of questioning you're putting out, I'm assuming you're dealing with an existing muffler that's been fused onto the inner pipe, which is why I'm suggesting a cut-off wheel in the previous question. Assuming you had to cut the old one off, you would cut back the existing muffer enough distance to fit the right adapter onto it to get it back to the right length (provided there's enough pipe to work with). Otherwise, just replace the receiving pipe with a new one. they're usually cheap, like 30~40 bucks, and they'll have a flanged side at the end closer to the engine so you *know* you can remove it without cutting pipe.

    A properly fitted aftermarket muffler will not need to be welded on it should slip on and fasten with a decorative clamp.

    The actual welds on the muffler were most likely Mig or Tig welded before being chromed or treated with blackout.

    No matter what some dimwits tell you, mufflers are not installed by "brassing".

    The answer to your question all depends on the materials to be joined, how nice you want it to look, the quality of the shop and how much you're willing to pay. Most production exhaust work is MIG welded and higher end stuff is TIG welded.

    Shop around and ask questions before dropping your cash. Ask to see a sample of their work.

    Tig welding is the top of the line in terms of welds but it is overkill for a non-structural component like an exhaust. Usually, exhaust systems are MIG welded.

    They do not actually weld it-it's a method using acetilyn and O2 orOxygyn called brazing, with the torch and a had help brazing wire-this is the most common

    most aftermarket mufflers are clamp on.Any type welding would ruin the chrome

    None. The overwhelming majority are slip on or bolt on in design.
