my wanting to "keep the car original" but have the extra giddy-up. I in NO WAY intend to try and justify my reasoning. Retarded? MAYBE! In fact, almost certainly! But dammit I like it so Im stickin to it LOL.

Exhaust

Cast iron exhaust manifolds are mandatory and must be from period 1960- 1975.

Under no cirspoogestances will headers be allowed, including those cars that had headers delivered in the trunk

Exhaust systems may be upgraded to a maximum of 2.5" diameter head and tail pipes. Certain cars such as 63' Max Wedge Plymouths & some SD Pontiacs had 3" exhaust outlets & head pipes, these are allowed if your car originally came with them. Pipes must exit in the correct* original location. lers must be stock looking in design, that is oval in shape.

No glasspacks or straight-through pipes allowed. Excessive exhaust leaks are not allowed.

X-pipes and H-pipes allowed You must run full exhausts at all times. No Cutouts.

If you think your exhaust sounds too loud it probably is, and will not be legal.
