.................I'm running a straight pipe on my 85 Jetta TD, mainly
because the rear muffler was so heavy that the hangers kept failing year
after year and the whole system was dominated by that weight. It is a
little loud now around town when I wind out the engine, but on the highway
it is very endurable.

.............If I were running a big diameter pipe that wouldn't go over
the axle, I'd try to link the big round pipe up with a thinner but wider
double pipe above the axle, using a "Y" pipe to split the big volume into
two smaller volumes just in front of the rear axle. The double smaller
pipes could clear the rear axle and exit at the rear without being joined
up again.

..................I rigged such a contraption to spray the radiator of a
big Chrysler that I used to pull our 7,000 pound travel trailer. I used the
30 gallon trailer tank as a supply, and pressurized it with the existing
trailer water supply pump. The flexible garden hose took water from the
trailer and delivered it to the dual spray nozzles in front of the
radiator. It worked well and I drove the rig clear across the USA and the
Canadian Rockies one summer. Took it off when I sold the car and trailer.
Still out in the garage.

..............I drove a new 1.8T Passat about 300 miles a few weeks ago,
and verify that it didn't have the performance that I like.  That same
engine is a lot snappier in a Jetta.    Doyt
