99 L31/4L60E in 71 update:Exhaust system
Well, spent the whole day yesterday (Friday) cutting, welding and fitting my new system. As you can see the old system was functional, yet very ugly. I used all mandrel bends and went over the axle instead of in front of the rear wheels, and added a third muffler to tame things down a little.
Just need to redo the fuel system (removing the cab tank) so I can hear what it sounds like.  And the new one....man I went through a lot of wire and gas in my MIG!!:   Tim

Looks good, but why did you do the Y-pipe?
