    Exhaust pipe...

    Not really too much of a technical question this one but...

    After squashing the centre muffler on my Disco I took my car to the mechanics for repair and was given a choice:

    1) Replace the centre muffler - $250ish.
    2) Go for a new "straight through" exhaust. Nicer sound, bit more power etc.. - $900ish.

    Given that at the time money was short I naturally opted for the cheaper option.

    What only occured to me the other night (after having a look under my car and seeing how the new muffler had been inserted) was why couldn't the damaged muffler (and the rear mufler) be removed and simply replaced by a straight piece of pipe to create a straight through exhaust?

    Is there more to it than that? I'm sure there must be

    Those prices seem a bit $$$$$$. you might want to try a few more exhaust shops.

    The exhaust shop wouldn't be replacing the muffler with a section of pipe, they'd use a 'straight through' muffler which should have been better worded as 'free flow'. They can replace the somewhat restrictive original muffler with a better flowing design.

    $900 sounds like it would be the whole exhaust system though maybe even including extractors.

    hes got a v8, you need at minum the rear resornator to remain fitted.
    i installed a 2.5'' system from the headders back without mufflers.... way to frikkin loud. i installed a round glass packed resornator at the rear, this worked a treat. and yes, you can just have a straight bit of pipe installed in place of the bent one, or have them fit a ''sports'' typr muffler.

    900! tell him hes dreamin...should be closer to 500 headders back.

    cheers phil
