1968 Modified Production

Yes, the NHRA required the same 'stupid' rule.

Exhaust pipes were required, and replacement production-type Mufflers had to be 18" in length.

The Mufflers had to be placed in the 'stock location', or if
they were originally installed behind the Rear-Axle, they
could be re-positioned in front of the Axle.

The Exhaust Outlets had to exit equal to the center-line
of the Rear-Axle.

Here is the Motion Performance A/MP 1968 Camaro.
