Grilled Sidepipes

The punched grill pipes to the left were a very common custom addition to early vans, while the Thrush side pipes seen on the far left were a bit more common on muscle cars and 70's vans. Either would provide a period-correct 70's look. 

Four-Into-Ones

Four-into-one side pipes have a bit more of a performance vibe and are a great addition to any  van whether 1st, 2nd, 3rd or even later-generation. On the downside, not being shielded can mercilessly "brand" your leg and make you curse the custom gods for choosing this style. Still, the look may be worth the risk. Pssssst! Yeow.

Zoomies

Zoomie style exhaust provided a bit more of the indoor custom car show look and are a bit impractical given the fact that they collect water in a rain storm. But that didn't stop a lot of folks and doesn't have to stop you, either.
