@JBugsVWParts For me it depends on what I'm starting with.
Half-done swing axle project? Traditional.

@lippyent Pretty regularly.
I have customers that have used shops that chronically over tighten filters.
And Ford conveniently placed that filter in a bad spot on a few different models for years.
@nelmagene2010 Trying to eliminate exhaust drone made worse by removing the catalytic converters.
Not for damping engine balance issues as stated elsewhere.
@DeTocqueville14 War creates fear. Fear creates a desperate unity that makes for easily controlled people.
On the plus side, the cult of Malthus will be pleased.
