[Vwdiesel] Caddy Exhaust

[Doyt W. Echelberger]

"Has anyone tried putting a straight pipe on a VW turbodiesel & if so, what
were the results? Any MPG improvement? Was it to noisy? I have heard that a
turbo quiets the exhaust enough to make it legal."  Bill Toensing, Nevada

Hello Bill....I ran a straight pipe on my 85 Jetta TD for years. The stock 
muffler under the trunk was a huge heavy boat anchor thing  and  the pipes 
in and out developed cracks, due to resonating vibrations of the diesel 
system. when it was threatening to drop off, I just dropped the whole stock 
set-up and swapped in a straight pipe all the way from the original 
downpipe connection. I remember being amazed by the size and weight of that 
huge old muffler after I got it off.

The straight pipe was quiet enough except when I really floored it and ran 
it up through the gears flat out like a race car. Then you could hear it a 
block away. But I didn't do that very often, and never in town where law 
enforcement might investigate.
