I lost my rear muffler today.... car sounds better too....

Actually it is not loud at all, just a bit of a sporty sound (and the car is 30lbs lighter).

Before I go and spend a bunch of $$$ on replacement parts, does anyone have advice on the subject??

Is there such a thing as "free flow" for diesels???

Any 240 driver will understand where I am coming from, that is, to pick up a horse or two would be nice...

But, if not I'll stay with stock set up.
anybody have any advice??
thanks
